In this paper, we analyze attacks on existing time synchronization protocols for wireless sensor networks. We propose a secure time synchronization toolbox to counter these attack...
Abstract. This paper evaluates the performance of INSENS, an INtrusion-tolerant routing protocol for wireless SEnsor Networks. Security in sensor networks is important in battlefi...
We define a new mode of operation for block encryption which in addition to assuring confidentiality also assures message integrity. In contrast, previously for message integrity...
Abstract. We investigate several alternate characterizations of pseudorandom functions (PRFs) and pseudorandom permutations (PRPs) in a concrete security setting. By analyzing the ...
