ASIGN:- CRYPTOGRAPHY Perform decryption and encryption using RSA algorithm with p= 3, q = 11, e =7 and N = 5.

Cryptography problem mathematics Suppose Alice and Bob are using a cryptosystem with a 128-bit key, so there are 2128possible keys. Eve is trying a brute-force attack on the system.(a) Suppose it takes 1 day for Eve to try 264 possible keys. At this rate, how long willit take for Eve to try all 2128 keys? (b) Suppose Alice waits 10 years and then buys a computer that is 100 times fasterthan the one she now owns. Will she finish trying all 2128 keys before or after whatshe does in part (a)?

It is vital to understand the differences between encoding and encryption.

While attempting to decipher a short message, assaults on a cipher provide a greater challenge since they are more difficult to break.
