WebMar 22, 2024 · Idea of ElGamal cryptosystem: Suppose Alice wants to communicate with Bob. Bob chooses a very large number q and a cyclic group Fq. an element a such that gcd (a, q) = 1. Then he computes h = g a. Bob publishes F, h = ga, q, and g as his public key and retains a as private key. such that gcd (k, q) = 1. Then she computes p = g k and s = … WebLemma: OTP has perfect secrecy. Proof: For every message m and every ciphertext c: Pr [E (k,m)=c] = #keys k in K s.t. E (k,m)=c Total number of Keys. Suppose that we have a cipher for all m,c: k in K: E (k,m)=c is equal to some constant. If that is the case then for all m 0, m 1 the probability of E (k,m)=c is the same and Dan states the the ...

WebJul 17, 2024 · A simple example of a substitution cipher is called the Caesar cipher, sometimes called a shift cipher. In this approach, each letter is replaced with a letter some fixed number of positions later in the alphabet. For example, if we use a shift of 3, then the letter A would be replaced with D, the letter 3 positions later in the alphabet. chuck rackWebOct 13, 2015 · If an attacker uses a chosen-cipher-text attack, how can they decrypt any plaintext by choosing 128 ciphertexts? I'm not exactly sure in which direction I have to think. I believe decryption will also be linear since in linear algebra the inverse of a linear function is also linear.
