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). WebCryptography is a continually evolving field that drives research and innovation. The Data Encryption Standard (DES), published by NIST in 1977 as a Federal Information …
WebSteps for RSA Algorithms: Choose the public key E such that it is not a factor of (X – 1) and (Y – 1). Chose the private key D such that the following equation becomes true. Send the CT to the receiver. Note: In the RSA algorithm, selecting and generating a public key and the private key is a critical task.
