ABSTRACT:
A method of encoded communication in which a receiver generates a receiver public key by looking up a monitoring authority public key, multiplying four prime numbers, and encoding the identities of two of the prime numbers with the monitoring authority public key. The receiver communicates the public key to a sender, who creates a message, encodes it with the receiver public key, and transmits it to the receiver. The receiver then decodes the encoded message with the four prime numbers. The monitoring authority may decode the two prime numbers of the receiver's key, and factorize the product of the remaining primes. An unauthorized party would be faced with the much more difficult or impossible task of factorizing the original product of the four primes.
