In this paper, we present a data hiding algorithm for binary document images. This algorithm is based on the DistanceReciprocal Distortion Measure [1] that is used to evaluate the...
Abstract Two protocols for authentication based on symmetric key cryptography are described, where the verifier can be implemented in software completely, without the need for secu...
Abstract. In this work we present a security model for low-value transactions in ad-hoc networks in which we focus on authentication since this is the core requirement for commerci...
Abstract— In highly open systems like the Internet, attributebased access control (ABAC) has proven its appropriateness. This is reflected in the utilization of ABAC in authenti...
