Abstract. DES and triple-DES are two well-known and popular encryption algorithms, but they both have the same drawback: their block size is limited to 64 bits. While the cryptogra...
In this paper, we present a new method for sharing images between two parties exploiting homomorphic property of public key cryptosystem. With our method, we show that it is possib...
Motivated by the tradeoff between security and efficiency performance parameters that has been imposed on all modern wireless security protocols, we designed a novel security syst...
Abstract. Assuming an insecure quantum channel and an authenticated classical channel, we propose an unconditionally secure scheme for encrypting classical messages under a shared ...
