— Assuring cryptographic integrity of mutable fields in any on-demand ad hoc routing protocol is more challenging than that of non mutable fields. We propose an efficient auth...
This article proposes a simple key management protocol for the distribution of shared session keys in IEEE 802.11 wireless LANs. For this purpose an individual key for each user i...
Abstract. We demonstrate two classes of attacks on EC-RAC, a growing set of RFID protocols. Our first class of attacks concerns the compositional approach used to construct a parti...
In the security chain the weakest link is definitely the human one: human beings cannot remember long secrets and often resort to rather insecure solutions to keep track of their ...
This paper presents efficient secure auction protocols for first price auction and second price auction. Previous auction protocols are based on a generally secure multi-party prot...
