Introduction to RSA and to Authentication The most famous of the public key cryptosystem is RSA which is named after its three developers Ron Rivest, Adi Shamir, and Leonard Adleman. 2 0 obj The report provides a list of recommended cryptographic algorithms (e.g. As the name describes that the Public Key is given to everyone and Private key is kept private. To encrypt a ﬁle, it is suﬃcient to break up the ﬁle into blocks so that each block can be treated as a number and encrypted by the RSA algorithm. The RSA algorithm is encrypt the original image and decrypts the image by the different keys. Now say we want to encrypt the message m = 7, c = m e mod n = 7 3 mod 33 = 343 mod 33 = 13. With the public key encryption system, we need 2 keys (one public and one private key) per user. RSA is based on the intractability of factoring large integers.
