X-WR-CALDESC:14 December 1977: Ronald Rivest\, Adi Shamir\, and Leonard Adl
eman file for a patent for what came to be the RSA public-key encryption a
lgorithm (named after the inventors). The patent was awarded on 20 Septemb
er 1983. Pictured in the photo - left to right: Adi Shamir\, Ron Rivest\,

mps.mcmaster.ca. \n\nExcerpt from 'RSA Public Key Encry
ption': U.S. Patent 4\,405\,829 was awarded to the Massachusetts I
nstitute of Technology on September 20\, 1983 for its 'Cryptographic commu
nications system and method.' The three inventors\, which the patent is na
med after\, are Ronald Rivest\, Adi Shamir\, and Leonard Adleman. The pate
nt expires 17 years from the date it was issued\, Sept 21\, 2000.\n\nThe R
SA cryptosystem\, as described in the patent\, is a public-key cryptosyste
m that offers both encryption and digital signatures. The cryptosystem is
able to encrypt and create digital signatures by taking advantage of the f
act that factoring is a 'hard' mathematical problem. Factoring is actually
one of three commonly used 'hard problems' for cryptography\; the other t
wo are the discrete logarithm problem and elliptic curves.\n\nThe RSA cryp
tosystem has been incorporated into popular products such as Secure Socket
Layer (SSL) and Secure Shell (SSH) as well as numerous other commercial p
roducts.
