RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission. The initialism "RSA" comes from the surnames of Ron Rivest , Adi Shamir and Leonard Adleman , who publicly described the algorithm in 1977.
Leonard Adleman (born December 31, 1945) is an American computer scientist. He is one of the creators of the RSA encryption algorithm, for which he received the 2002 Turing Award . [ 1 ] He is also known for the creation of the field of DNA computing and coining the term computer virus .
Along with Adi Shamir and Len Adleman, Rivest is one of the inventors of the RSA algorithm. He is also the inventor of the symmetric key encryption algorithms RC2, RC4, and RC5, and co-inventor of RC6. (RC stands for "Rivest Cipher".) He also devised the MD2, MD4, MD5 and MD6 cryptographic hash functions.
Adi Shamir (Hebrew: עדי שמיר; born July 6, 1952) is an Israeli cryptographer and inventor. He is a co-inventor of the Rivest–Shamir–Adleman (RSA) algorithm (along with Ron Rivest and Len Adleman), a co-inventor of the Feige–Fiat–Shamir identification scheme (along with Uriel Feige and Amos Fiat), one of the inventors of differential cryptanalysis and has made numerous ...

RSA Security LLC, [5] formerly RSA Security, Inc. and trade name RSA, is an American computer and network security company with a focus on encryption and decryption standards. RSA was named after the initials of its co-founders, Ron Rivest , Adi Shamir and Leonard Adleman , after whom the RSA public key cryptography algorithm was also named. [ 6 ]
RSA uses exponentiation modulo a product of two very large primes, to encrypt and decrypt, performing both public key encryption and public key digital signatures. Its security is connected to the extreme difficulty of factoring large integers , a problem for which there is no known efficient general technique.
Whitfield Diffie, Martin Hellman, Ronald Rivest, and Adi Shamir at RSA 2008. Leonard Adleman, US, USC, the 'A' in RSA. David Chaum, US, inventor of blind signatures. Clifford Cocks, UK GCHQ first inventor of RSA, a fact that remained secret until 1997 and so was unknown to Rivest, Shamir, and Adleman.
