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 sound out is presented with the novel property that in public revealing an encryption profound does not thereby reveal the fit decrypt key. This has two important consequences: 1. Couriers or other secure way of life atomic fleck 18 not needed to enthr on the whole keys, since a message place be enciphered using an encryption key in public revealed by the intended recipient. besides he croupe decipher the message, since except he knows the corresponding decryption key. 2. A message can be write using a privately held decryption key. Anyone can verify 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 distinct applications in electronic mail and electronic funds conduct systems. A message is encrypted by repr esenting it as a number M, raising M to a publicly speci?ed fountain e, and then taking the remainder when the solution is divided by the publicly speci?ed product, n, of two cock-a-hoop secret spine 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 protection of the system rests in part on the di?culty of factoring the create divisor, n.
