This paper presents a novel framework for the generic construction of hybrid encryption schemes which produces more efficient schemes than the ones known before. A previous framew...
In a practical system, a message is often encrypted more than once by different encryptions, here called multiple encryption, to enhance its security. Additionally, new features ...
Abstract. In 14] and 21] there are proposed ElGamal-type cryptosystems based on non-maximal imaginary quadratic orders with fast trapdoor decryption. The trapdoor information is th...
We study the data privacy of cryptosystems with All-or-Nothing transform (AONT). An AONT is an efficient computable transform with two properties: Given all the bits of its output...
E-mail system has become one of the most important and popular Internet services. Instead of using traditional surface mail, we have the alternative of employing e-mail system whic...
