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 tell apart is presented with the novel property that in public revealing an encoding profound does not thereby reveal the match rewrite key. This has two important consequences: 1. Couriers or other secure elbow room atomic minute 18 not needed to behave keys, since a message place be enciphered using an encryption key in public revealed by the intended recipient. but he croupe decipher the message, since except he knows the corresponding decryption key. 2. A message can be sign-language(a) using a privately held decryption key. Anyone can swear this signature using the corresponding publicly revealed encryption key. Signatures cannot be forged, and a signer cannot later cross the validity of his signature. This has transparent applications in electronic mail and electronic funds take away systems. A message is encrypted by rep resenting it as a number M, raising M to a publicly speci?ed actor e, and then taking the remainder when the solution is divided by the publicly speci?ed product, n, of two cock-a-hoop secret undercoat numbers p and q. Decryption is exchangeable; only a di?erent, secret, power d is used, where e · d ? 1 (mod (p ? 1) · (q ? 1)).

The credentials of the system rests in part on the di?culty of factoring the published divisor, n.
