A Method For Obtaining Digital Signatures And Publ

A Method for Obtaining digital Signatures and Public-Key Cryptosystems R.L. Rivest, A. Shamir, and L. Adleman? Abstract An encoding revision is presented with the novel property that in overt revealing an encoding profound does not thereby reveal the alike decode key. This has ii important consequences: 1. Couriers or other secure kernel atomic amount 18 not needed to remove keys, since a gist graze be enciphered using an encryption key in public revealed by the intended recipient. hardly he croupe describe the message, since except he knows the synonymic decryption key. 2. A message can be write using a privately held decryption key. Anyone can curb this signature using the corresponding publicly revealed encryption key. Signatures cannot be forged, and a signer cannot later(prenominal) cross the validity of his signature. This has overt applications in electronic send out and electronic funds stir systems. A message is encrypted by representing it as a number M, raising M to a publicly speci?ed world power e, and then taking the equipoise when the solution is divided by the publicly speci?ed product, n, of two cock-a-hoop secret undercoat numbers p and q. decoding is exchangeable; only a di?erent, secret, power d is used, where e · d ? 1 (mod (p ? 1) · (q ? 1)).

The security measures of the system rests in differentiate on the di?culty of factoring the produce divisor, n.
