NPTEL is planning to conduct the Jan-Apr 2020 semester exams (online remote proctored AND/OR in-person exams) in the coming days, based on prevalent government guidelines at that time. If you wish to write this exam - whenever we conduct it - we will retain the fees you had paid earlier and,

• Inform you as & when we plan to conduct the exam for the subject you have registered.

• You will be informed of the mode and date of the exam.

• At that point if you are unable to write the exam, you will be allowed to cancel the registration and take the refund.

By choosing this Option 1, you also agree that:

If I choose Exam and I am absent for it OR do not pass the exam based on NPTEL criteria, I will not get a certificate or refund of fees.

2. OPTION 2: "I wish to cancel and take refund"

In case you do not wish to write the exam for the NPTEL course offered in Jan 2020, please choose this option.

NPTEL: Latest update on Exams for Jan 2020 semester

Dear learner,

This is with regard to the Jan-Apr 2020 NPTEL exams. Based on the feedback received the last couple of days from several stakeholders such as learners, colleges, etc, we have decided on the following:

Cancelling the exams scheduled for 23/24/25 June through TCS

1. Attested Assignment Score sheet:  For ALL exam registered candidates:

We will issue an attested assignment score sheet letter, regardless of your assignment score - which can be used as appropriate.

2. Modified Pass certificate: Based on Average Assignment score

We will calculate the Average Assignment score as follows:

Average of the best 3/6/8 assignments for courses of duration 4/8/12 weeks (or as announced apriori in the course in case of changes)

If this score >= 40/100 (which is also one condition for certificate eligibility), we will issue a modified Pass certificate.

If this score <40/100, this certificate will not be issued.

This certificate will not be counted towards the Domain certification as a completed course. Similarly, we will not be issuing an AICTE-NPTEL FDP certificate also based on this.

3. A generic letter from our side - request to College authorities to accept this as per their requirement will be put up on nptel.ac.in, can be downloaded and used

We will put up a pdf in which we will explain the assignment score sheet and the Pass certificate and request them to accept and process further. We will also independently approach the ministry, AICTE and UGC to convey this new process for Jan 2020 semester to all universities.  

Regarding the conduct of exams in future:

Independent of the Pass certificate and the Attested assignment score sheet mentioned above, in order to plan for a possible exam sometime in the future, we will share another form after the above activities are completed, with 2 choices:

 

a. Cancel and refund - Those who are very sure that they would not want to appear for regular proctored NPTEL exams and want a refund - can choose this. We will refund the money. We may not be able to open registrations again in this case if you wish to appear for it later.

If you pass, you will be eligible for NPTEL course certificate

OPTION 3: CANCEL EXAM AND TAKE A REFUND
NPTEL certificate will NOT be issued in this case and you will only get an attested assignment score sheet.
Last date to fill this form: June 7 2020 - 10am
Link to the form :bit.ly/NPTELExamOptionForm
***************************************************
More details about the options:
Option 1: What is required to choose Online remote proctored exam?
We have finalized an online exam vendor with remote proctoring to conduct exams for those who have the following facilities:

• A laptop/desktop with webcam, audio and stable internet connection.
• You can write the exam from wherever you are.
• Please check system requirements shown below.

If you wish to take the remote proctored online exam online, please follow the following steps.
STEP 1:
Mock Test
You will receive an email with Link for a Mock Test. Please go ahead and use this link to test your system requirements and compatibility.

• The duration of this Mock test will be 10 mins.
  
• This Mock Test has to be completed in order to check your system’s compatibility to take the remote proctored online exam.
• Hence, completing this Mock test is Mandatory for those who wish to take the remote proctored online exam.
• Those who do not complete the Mock Test successfully will not be able to participate in the remote proctored online exam.

STEP 2:
If you are able to successfully complete the Mock test and submit the answers to the dummy questions, you can opt for the remote proctored online exam.
Please note:
If you are unable to complete the mock test (due to system infrastructure mismatch - webcam not working or insufficient internet speed,etc) we will not be able to include you for the online remote proctored exam.
Please choose the Backup option in case the trial for the online remote proctored exams to be held this week do not go well.You can either opt for in-person exams at designated centres or cancel the exam and take a refund.
*****************************************************
OPTION 2: IN PERSON PROCTORED EXAM AT FIXED EXAM CENTRES

We will be conducting exams with TCS iON (like we normally do) for which you have to appear in person at the designated exam centre in the city chosen by you.
The exam dates will be 23,24,25 June 2020 for this.

• We will ensure you will be able to write the exams you have registered for without a clash in slots.
• We, along with the exam partner, will make sure that exams will be conducted by following appropriate social distancing norms and hygiene rules as required in the current situation.
• It will be your responsibility to ensure that you reach the centre to give the exam.
• We will try and ensure conduct of exam in the cities given in the list, but if in case for any unforeseen reason, we are unable to conduct the exam in the city chosen by you, we will refund 80% of the exam fee and you will not get the certificate from us.

Same final score calculation and pass criteria as mentioned in the Course introduction page will be applied and NPTEL certificates will be given as per that.
*************************************************************
OPTION 3: CANCEL EXAM AND TAKE A REFUND
You can choose to cancel your exam and take a refund. We will refund 80% of the fee you have paid, retaining 20% towards administrative costs. An attested assignment score sheet will be issued to you in this case.
Link: bit.ly/SampleAssignmentLetter
In this case, you will NOT get an NPTEL certificate for the course.

*****************************************************
IMPORTANT:

• Those of you graduating this year and who definitely need an NPTEL certificate - we suggest that you should make a serious effort in attempting this online remote proctored exam. As you know, the in-person-at-centre exam has a lot more dependencies on external factors. So please try to arrange for the systems per the requirements and attempt this online exam.
• The above 3 options can be exercised for each of the courses registered for individually.
• If you pass the course as per the certification criteria, the certificate will be the same as we normally give.
• You can choose either the online exam session or the in-person session to write the exam. If you miss that we will be unable to provide another opportunity to take up the exam this semester. The fees paid will be used towards this one session.
• Fees will not be refunded if you participate in this exam and then could not complete the exam for any reason whatsoever.

Warm regards

Foundations of Cryptography: Typo in the slide on RSS

Dear Particioants

In lecture no 56 on Secret Sharing, slide no 7 (replicated secret sharing) there is a typo. The instances of additive secret sharing are instantiated with threshold t and not t+1. Namely the instances are (t+1, t) and not (t+1, t+1). We need in each instance, all t+1 parties are needed to reconstruct the secret, while any set of t share-holders in that instance should fail to reconstruct back the secret.

Foundations of Cryptography: Typo in Lecture no 51

Dear Participants

In the lecture no 51 on digital signatures, there is a typo in the correctness definition (slide no 4). We need that any legitimately signed message should pass the verification, instead of failing, except with a negligible probability. And signature verification pass means that output of verification should be 1, while output 0 means that signature verification fails. So in the correctness expression, it should be 0, instead of 1. Namely

Pr[Vrfy_vk(m, (sign_sk(m))) = 0] <= negl(n)

instead of 

            Pr[Vrfy_vk(m, (sign_sk(m))) = 1] <= negl(n)

Foundations of Cryptography: Correction in Q2 of assignment 8

Dear Participants

In Q2 of week 8 assignment, the last statement is incorrect. In the encrypt-and-authenticate approach, at the sender's end the operations can happen in parallel. But at the receiver's end, the operations can happen only in sequence: first ciphertext c has to be decrypted and then tag-verification happens. Kindly see the solution manual for details.

The NPTEL team has been informed about this and Q2 will be re-evaluated. 

Best Regards

Ashish

Foundations of Cryptography : Minor typo in Lec 35

Dear Partcipants

For the second module of Week 8 (lec 35.mp3), the following minor typo occurred in all the slides describing the authenticate-then-encrypt approach:

all occurrences of Dec_KeKm(c||t) should be replaced by Dec_KeKm(c), as the decryption algorithm takes ONLY c as the input. Internally, on decrypting c, we recover m||t and then check if t is the tag for the recovered m or not.

Foundations of Cryptography: Few Announcements Regarding Assignment 7

Dear Participants

Few announcements regarding recently concluded assignment 7:

1. For Q3, the option b is incorrect. The correct answers are (a) and (c). You can see the details in the updated solution manual

2. For Q8 and Q9, there were few options which are based on the contents of week 8. So we are scrapping these questions and adjusting their respective weights with Q1 and Q2, which were the easiest questions for assignment 7. So now the weights of Q1 and Q2 are 2 marks each.

3. The updated solution manual for assignment 7 is available at the following link

Foundations of Cryptography course : Few announcements

Dear All

1. Please wait for the solution manual for a particular week's assignment to be uploaded and if you are still not satisfied, then only post your queries. I can understand that sometime a participant might be very desperate to know why her/his solution is incorrect and ends up posting the query in the forum. It becomes difficult to answer each and every such query. Instead, just wait for the solutions to be uploaded and I am sure your doubts will be clarified.

2. I have seen the feedback for the first 3 weeks and a common comment is that I should not ask MCQ type questions and also I should not ask tricky questions and I should give partial marks for each question. The reason I am not giving partial marks is that otherwise a "smart" participant can just end up selecting all the options for a particular question and he/she will end up getting some marks. Regarding the "trickiness", let me assure you that if you are indeed following the lectures and going back and reading the concerned portion from the reference book, then for each assignment, you should be able to solve at least 5-6 questions. Each of the assignments are designed like that. Its only 2-3 questions per assignment, which are indeed tricky.

3. Many people asked for the slides. The slides are purposely not provided, as in the past, my course slides were terribly misused. 

4. Many people asked for notes. Its really difficult to provide the exact notes, matching the video contents. However, if you are indeed interested in notes, then kindly refer the book by Katz-Lindell or Boneh-Shoup. I closely follow these books. The whole purpose of the online videos is that they act as a video reference for the text-book material. I tried my level best to present the materials from the above references (specially Katz-Lindell) in a simple form, so that after watching the videos, if one goes back and read the relevant topics from Katz-Lindell, then its easily understandable. The candidates are expected to go back and read text-book, as this is an advanced level graduate course. For the sake of formality, the transcribed notes will be provided before the exam. However, its better to directly read the relevant portions from Katz-Lindell or Boneh-Shoup.

5. Some people feel that the course material is highly advanced. Well, there are two ways to teach cryptography. The simple "khichdi" way, where you just end up learning lots of algorithms and end up mugging up the steps of algorithms, where the algorithms are presented in an adhoc order (public-key primitives, followed by symmetric-key primitives and so on). This approach is typically used in the so called "cryptography and Network security"  or "Introduction to Crytpgraphy" course and this approach is the approach which is followed in less rigorous text books like Stallings.  This way you just end learning some algorithms, but not the science aspect of cryptography. The second and more rigorous and formal approach is the one, which I am following in the course, which is followed in Katz-Lindell and Boneh-Shoup. And to understand this approach, you also need to work hard, make your own regular notes, read lots of textbook materials, try to practice unsolved problems, search about the covered topics in the Internet, etc. Dont think that just by listening to the video lectures, you will learn cryptography. Take the following analogy: Guru Drona (I am not comparing myself with Drona though) gave the same archery lessons to Pandavas and Kauravas, but its only Arjuna, who just for his own interest worked super and extra hard on his own, practiced on his own and took the best of his Guru's teachings. Same way, if you are really interested in learning the science aspect of cryptography, you have to work hard. 

I am sorry for my long post, but based on the comments that I have received till now, I thought of clearing the air somewhat.

Best Regards

Foundation of Cryptography : No Partial Marks for Assignments

Dear All

I have seen numerous number of posts in the discussion forum, regarding partial marks for the assignments. Let me be very clear: you will get marks ONLY if you select ALL the correct answers. The questions are very simple, and in fact 5-6 of the questions in every assignment are based on what you see in the video lectures and its only the remaining 4, which are mildly tricky. If you are struggling even to get at least 6 out of 10 in every assignment, then its very sad!!

I will not respond to any of the further requests regarding partial markings in the assignments.

Regarding problems in assignment evaluations

Dear Participants

The NPTEL team shared the following document, to address some of the technical issues, related to assignment evaluations.

https://docs.google.com/document/d/1ttwUvNAgvT5CPIzi_Yz4XWqVHxpMZGPUqM2X3HoqMaM/edit?usp=sharing

 I request all of you to go through it and check if your concerns are addressed. Believe me, I have no "manual" control over the assignment evaluations, as all the assignments are "auto-evaluated", based on the answers you select and the correct answers which had been already stored in the system. If you still have any queries/concerns, request you to kindly contact the NPTEL team.

Best Regards
