Dated: 06‐02‐13
 
This is notified that the following Roll Nos. appeared in SET, 2012 (held on 09‐09‐12) are declared qualified for Lectureship in Colleges and Universities of N. E States including Sikkim.
 
The criteria adopted during the finalisation of the result follows:
“Those candidates who figure among top 7% of all the candidates who appeared in SET,2012; this shall be calculated separately for each disciplinen and for each category (OBC,SC/ST/PH/VH).

Accordingly a cut‐off mark will be determined for each subject and each category for this purpose. In case of the tie (when several students have same identical aggregate marks) all the candidates
appearing at the qualifying marks shall be included. Candidates who do not secure minimum required score in each paper and are therefore not in the consideration Zone, will not be included in this list if they fall among top 7% within their subject and category”

8. Using RSA algorithm, what is the value of cipher text C, if the plain text M=5 and p=3, q=11 & d=7?

(A) 33

(B) 5

(C) 25

(D) 26

Ans:D

n = (p x q) = (3 x 11) = 33

f(n) = (p – 1)(q – 1) = (3 – 1)(11 – 1) = (2)(10) = 20

e must be relatively prime to f(n);

Factors of 20 = 1, 2, 4, 5, 10, 20

Factors suitable for e = 3, 4, 5, 6, 7, ….

Try 3.  Factors of 3 = 1, 3

Selecting 3 meets requirement to be relatively prime to f(n).

We also know d = e^-1 mod f(n); that is ed = 1 mod 20

We also can find 1 mod 20 = 21, 41, 61, etc.

Testing ed = 21, then d = 21/3 = 7

Public Key is [3,33]

Private key is [7,33]

Encrypting:

C = m^e mod n = 5³ mod 33 = 125 mod 33 = 125/33 = Q of 3, R of 26

So C = 26

45. What is the result of the following expression? (1 &2) + (3 &4)

(A) 1

(B) 3

(C) 2

(D) 0

Ans:D

(1 & 2) + (3 & 4)

=( 001 & 010) + (011 + 100)

=(0) + (0)
