Consisting of a system of private and public keys, FTP, what is this encryption system named for its inventors, Ron Rivest, Adi Shamir, and Leonard Adleman.
In 1993, Peter Shor demonstrated that a quantum computer would render it obsolete. Daniel Ble-ichenbacher described the first practical adaptive chosen cyphertext attack against it using a redundancy function, and a method called blinding is used to thwart timing attacks. It is slower than DES and other symmetric cryptosystems, and it is important that the prime numbers used for it not be too close, which would allow attackers to find the by means of Fermat factorization. Since the 512-bit modulus was broken in 1999, it is recommended that moduli be at least 1024 bits long.
