Wireless mobile Ad Hoc Networks (MANET) are an emerging area of mobile computing. Security issues concerning MANET are attracting increasing attention nowadays. MANET is a new wireless networking paradigm without a fixed infrastructure, and includes base stations or mobile switching centers. Mobile nodes rely on each other to maintain the network(More)
In this paper, a method for the automatic handwritten signature verification (AHSV) is described. The method relies on global features that summarize different aspects of signature shape and dynamics of signature production. For designing the algorithm, we have tried to detect the signature without paying any attention to the thickness and size of it. The(More)
Short digital signatures are always desirable. They are necessary in situations in which humans are asked to manually key in the signature or when working in low-bandwidth communication environments. They are also useful in general to reduce the communication environments. We propose a short signature scheme based on knapsack and Gap Diffie-Hellman(GDH)(More)
