Realizing the time variant key or variable key from session to session is the key challenge in achieving perfect security [1-2]. Automatic Variable Key (AVK) is a novel approach to realize time variant key. In AVK, key is generated for use between the sender and the receiver in using a simple computation technique as proposed by Bhunia [3-5]. The AVK was widely experimented by other researchers that established the superiority of AVK over a single / fixed key [6-10]. In this paper we propose two new techniques for generating time variant key. Our techniques ensure better randomness among the successive two keys so generated.
