The source node (11a) may include a wireless communications device for establishing a wireless communication link with the at least one adjacent node (11b), a plain text source (24), and a second generator (20) for performing a one-way algorithm using a secret key for generating a seed. Furthermore, the source node (11a) may also include a key encryptor (22) for receiving the seed and generating a key sequence based thereon, and a logic circuit for generating a cipher text for transmission over the wireless communications link and based upon the key sequence and the plain text.
