DEAL is a six- or eight-round Luby-Rackoff cipher that uses DES as its round function, with allowed key lengths of 128, 192, and 256 bits. In this paper, we discuss two new result...
As distributed computing systems grow in size, complexity and variety of application, the problem of protecting sensitive data from unauthorized disclosure and tampering becomes i...
As a general design criterion, a symmetric key cipher should not be closed under functional composition due to the implications on the security of the cipher. However, there are s...
The electronic mail plays an unavoidable role in the humankind communications. With the great interest for the connection via mobile platforms, and the growing number of vulnerabil...
We present a new approach for creating chosen ciphertext secure encryption. The focal point ork is a new abstraction that we call Detectable Chosen Ciphertext Security (DCCA). Int...
