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.
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 ]
The name RSA refers to the public-key encryption technology developed by RSA Data Security, Inc., which was founded in 1982. The abbreviation stands for Rivest, Shamir, and Adleman, the inventors of the technique.
Asymmetric key cryptography, Diffie–Hellman key exchange, and the best known of the public key / private key algorithms (i.e., what is usually called the RSA algorithm), all seem to have been independently developed at a UK intelligence agency before the public announcement by Diffie and Hellman in 1976.
Both South Africa and Cuba claimed victory at the decisive battle of Cuito Cuanavale, which have been described as "the fiercest in Africa since World War II". [193] However, the South African military had lost air superiority and its technological advantage, largely due to an international arms embargo against the country. [194]
Later, the 128-bit RSA SecurID algorithm was published as part of an open source library. [4] In the RSA SecurID authentication scheme, the seed record is the secret key used to generate one-time passwords. Newer versions also feature a USB connector, which allows the token to be used as a smart card-like device for securely storing certificates.
On the RSA building's rear frieze, the words "The Royal Society of Arts" are displayed (see photograph at right), although its full name is "The Royal Society for the Encouragement of Arts, Manufactures and Commerce". The RSA has expanded into adjacent buildings, and now includes 2 and 4 John Adam Street and 18 Adam Street.
