An encryption system and method utilizes a bit stream, called a "master signature", which is divided into bytes with each byte being assigned a byte address. A portion of the master signature, called an "access signature" is randomly selected to encode the message to be transmitted. Both a sender and a receiver have the same access signature. The particular portion of the access signature to be used to encrypt and decrypt a message is identified at the sender by identifying the address of the first byte in this portion of the access signature and the number of bytes sequentially related to this first byte which together with the first byte will be used to encode the message to be transmitted. This information is sent to the receiver. Thus, using this information, the sender can encrypt and the receiver can decrypt the message using the same portion of the access signature. |
