Most Supervisory Control and Data Acquisition (SCADA) systems have been in operation for decades and they in general have 24x7 availability requirement, hence upgrading or adding ...
We define security goals and attack models for disk encryption, and prove several relationships between the resulting security notions, and some general results about disk encryp...
This paper proves "tight security in the random-oracle model relative to factorization" for the lowest-cost signature systems available today: every hash-generic signatur...
Recently, proxy re-encryption scheme received much attention. In this paper, we propose a proxy re-encryption used for divert ciphertext from one group to another. The scheme is bi...
Abstract. Known practical blind signature schemes whose security against adaptive and parallel attacks can be proven in the random oracle model either need five data exchanges bet...
