Key transmission system
First Claim
1. A method of encrypting data to be transferred between a pair of parties over a data communication system by making available to one party a public key of the other party that is mathematically related to the private key of the other party, said method including the step of selecting said public key to include a modulus comprising a binary representation of a product of a pair of primes p·
- q, said binary representation having a plurality of sets of bits, at least one set being of a predetermined pattern of bits corresponding to a portion of said modulus and representative of information exchanged between said parties and supplementary to said modulus and applying said public key to encrypt the message and transferring the encrypted message over said data communication system.

Abstract
A RSA encryption scheme includes a modulus in which at least one set of bits is of a predetermined configuration. The configuration may be selected to replicate the identity of the recipient or other information normally transmitted between the parties or may be information stored by the sender to allow only the balance of the modulus to be transmitted with the sender subsequently reconstructing the modulus.
