WebPublic Key Cryptography Each user has an encryption function and a decryption function. • Alice makes her encryption function E A publicly known, but keeps her decryption function D A secret. • Bob wants to send Alice a message P, so he computes C = E A(P) and sends it to her. • Alice receives C and computes P = D A(C). WebThe RSA Algorithm. RSA is an example of a public-key algorithm. Its security is based on the fact that factoring integers is a hard problem. The process is outlined below: To determine the keys: Choose two prime numbers \(p \and q\text{.}\) Let \(n=pq \and {m = (p-1)(q-1)}\text{.}\) Find any number \(e\) which is relatively prime to \(m\)
