We introduce a practical synchronous stream cipher with provable security named QUAD. The cipher relies on the iteration of a multivariate quadratic system of m equations in n <...
QUAD is a stream cipher whose provable security relies on the hardness of solving systems of multivariate quadratic equations. This paper explores FPGA implementations of the stre...
We give an outline of the specification and provable security features of the QUAD stream cipher proposed at Eurocrypt 2006 [6]. The cipher relies on the iteration of a multivaria...
We describe a systematic framework for using a stream cipher supporting an initialisation vector (IV) to perform various tasks of authentication and authenticated encryption. These...
It is desirable to store data on data storage servers such as mail servers and file servers in encrypted form to reduce security and privacy risks. But this usually implies that ...
