This chapter presents a keyless self-encrypting/decrypting system to be used in various communications systems. In the world of vast communications systems, data flow through various kinds of media, including free air. Thus the information transmitted is free to anyone who can peer it, which means that there should be a guarding mechanism so the information is transmitted securely over the medium from the sender to the intended receiver, who is supposed to get it in the first place and deter the others from getting the information sent. Many encryption systems have been devised for this purpose, but most of them are built around Public Key Infrastructure (PKI) wherein public key cryptography, a public and private key, is created simultaneously using the same algorithm (a popular one is known as RSA) by a certificate authority (CA). The private key is given only to the requesting party, and the public key is made publicly available (as part of a digital certificate) in a directory that all parties can access. The private key is never shared with anyone or sent across the medium. All of the commonly used encryption systems exchange keys that need to be generated using complex mathematical operations that take noticeable time, which is sometimes done once, and exchanged openly over unsecured medium. We are proposing an expandable keyless self-encrypting/decrypting system, which does not require the use of keys in order o minimize the chances of breaching data exchange security and enhance the data security of everyday communications devices that are otherwise insecured.
