The availability of secret keys is a precondition for the use of many security solutions and protocols. However, securely assigning such keys to nodes is a challenging task in the context of wireless sensor networks. In this paper we present a novel solution for a secure key assignment in wireless sensor networks that can be used during the initial configuration of nodes or for an ad-hoc key assignment...
Access control problem is a vital research topic which has been widely discussed in many years. Recently, several schemes for access control have been proposed. However, most schemes own some flaws in different perspectives. In this paper, we propose a secure key assignment scheme by utilizing the discrete logarithm, Diffie-Hellman key exchange, and a secure one-way hash function. In our proposed...
