RSA Encryption: Definition, Architecture, Benefits & Use
The RSA algorithm involves four steps: key generation, key distribution, encryption, and decryption. A basic principle behind RSA is the observation that it is practical to find three very large positive integers e, d, and n, such that with modular exponentiation for all integers m (with 0 ≤ m < n): and that … See more RSA (Rivest–Shamir–Adleman) is a public-key cryptosystem that is widely used for secure data transmission. It is also one of the oldest. The acronym "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, … 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 formulation used a shared-secret-key … See more Attacks against plain RSA There are a number of attacks against plain RSA as described below. • When encrypting with low encryption exponents (e.g., e = … See more Using the Chinese remainder algorithm For efficiency, many popular crypto libraries (such as OpenSSL, Java and .NET) use for decryption … 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". From 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.
