Computer system for centralized session key distribution, privacy enhanced messaging and information distribution using a split private key public cryptosystem |
摘要 |
An article of manufacture for effecting secure communications during a communications session between users in a secured communication cryptosystem in which users are each associated with a public crypto-key and a private crypto-key, includes computer readable storage medium having computer programming stored thereon. The stored computer programming is configured to be readable from the computer readable storage medium by a computer and thereby cause the computer to operate so as to generate a private crypto-key using a private exponent and a modulus N, which is the product of a plurality of numbers within a set of large prime numbers. The generated private crypto-key is divided into a private user key portion having a first bit length and a central authority key portion having a second bit length. The first bit length is smaller than the second bit length, and is no larger than fifteen percent of the bit length of the modulus N but no less than 56 bits. The private user key portion is directed only to a single user of the cryptosystem and the central authority's portion is directed to a central storage device.
