WebCryptanalysis of Pseudorandom Generators Instructor: Daniele Micciancio UCSD CSE As a motivating application for the study of lattice in cryptography we consider the construction of pseudorandom generators. We recall that a pseudorandom generator is a program G(x) (computable in deterministic polynomial time) that maps bitstrings x 2 WebStream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit.

Why I can get a key from frequency in Caesar Cipher?

WebAug 30, 2024 · I took a cryptanalysis class in university and I learned Caesar Cipher. But I cannot understand why frequency gives me the "key".
