Patent ID: 7917747

Claim:
A cryptographic communication system, comprising: i encryption keys K 1 , . . . K i , wherein i is an integer greater than 1; a first plurality of stations, each station in the first plurality of stations associated with at least one of the encryption keys K 1 , . . . , K i ; an initial data packet D 0 , the initial data packet D 0 available for review at each of the stations in the first plurality of stations; means for encrypting the initial data packet D 0 to form i encrypted data packets E 1 , . . . , E i , each encrypted data packet E m of encrypted data packets E 1 , . . . , E i encrypted according to the encryption key K m of encryption keys K 1 , . . . , K i by the station associated with the encryption key K m , where m ranges from 1 to i; and means for combining each of the encrypted data packets E m into a final encrypted data packet E f , wherein E f =( E 1 *E 2 * . . . *E i )mod M=D 0 P mod M wherein M is the product of multiplying a first prime factor F 1 and a second prime factor F 2 , wherein the means for encrypting is applied in parallel to allow each station in the first plurality of stations to view the contents of the data packet D 0 prior to encryption of the data packet D 0 , and wherein the encryption keys K 1 , . . . K i are used to form a public key P.
