Abstract
A mobile ad-hoc network may include a plurality of nodes including a source node and at least one adjacent node. The source node may include a wireless communications device for establishing a wireless communications link with the at least one adjacent node, a plain text source, and a seed generator for performing a one-way algorithm using a secret key for generating a seed. Furthermore, the source node may also include a key encryptor for receiving the seed and generating a key sequence based thereon, and a logic circuit for generating cipher text for transmission over the wireless communications link and based upon the key sequence and the plain text.
