The RSA algorithm is a kind of asymmetric encryption algorithm which appeared in 1978. 6 0 obj The algorithm is public key encryption algorithm which is a widely accepted and implemented by public. To treat each block as a number, simply concatenate the bit representation of the 3 bytes to form a single number. The results about bit-security of RSA generally involve a reduction tech-nique (see computational complexity theory), where an algorithm for solv-ing the RSA Problem is constructed from an algorithm for predicting one (or more) plaintext bits. RSA (an abbreviation of names Rivest, Shamir, and Adleman) is a public key cryptography algorithm, which is based on the computational complexity of the problem of integer factorization.
