The acronym "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was … See more The idea of an asymmetric public-private key cryptosystem is attributed to Whitfield Diffie and Martin Hellman, who published this concept in 1976. They also introduced digital signatures and attempted to apply number theory. Their … See more Proof using Fermat's little theorem The proof of the correctness of RSA is based on Fermat's little theorem, stating that a ≡ 1 (mod p) for any integer a and prime p, not dividing a. We want to show that Since λ(pq) = See more Using the Chinese remainder algorithm For efficiency, many popular crypto libraries (such as OpenSSL, Java and .NET) use for decryption and signing the following optimization based on the Chinese remainder theorem. The following values are … See more A patent describing the RSA algorithm was granted to MIT on 20 September 1983: U.S. Patent 4,405,829 "Cryptographic communications system and method".
