A Message Authentication Code Based on Latin Squares

An ECC-Based Mutual Authentication Scheme with One Time Signature (OTS) in Advanced Metering Infrastructure

Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...

Linear Codes Through Latin Squares Modulo n

It is known that t mutually orthogonal latin squares of order n generate a b t 2c-error correcting code with n codewords. In this paper we consider latin squares of order n made up of elements taken from Zn. In this situation we consider when this code is linear. We present neccessary and sufficient conditions on the latin squares and obtain a method of constructing a maximal family of mutually...

Message Authentication Using Hash Functions| the Hmac Construction

Two parties communicating across an insecure channel need a method by which any attempt to modify the information sent by one to the other, or fake its origin, is detected. Most commonly such a mechanism is based on a shared key between the parties, and in this setting is usually called a MAC, or Message Authentication Code. (Other terms include Integrity Check Value or Cryptographic Checksum)....

Master’s Project Proposal Ensuring data integrity with tamper evident encryption of integers using keyed Hash Message Authentication Code

New (Two-Track-)MAC Based on the Two Trails of RIPEMD

We present a new message authentication code. It is based on a two trail construction, which underlies the unkeyed hash function RIPEMD-160. It is in comparison with the MDx-MAC based on RIPEMD-160, much more efficient on short messages (that is on messages of 512 or 1024 bits) and percentage-wise a little bit more efficient on long messages. Moreover, it handles key-changes very efficiently. T...
