Secure Hashing Algorithms (SHA) showed a significant importance in today's information security applications. The National Institute of Standards and Technology (NIST), held a competition of three rounds to replace SHA1 and SHA2 with the new SHA-3, to ensure long term robustness of hash functions. In this paper, we present a comprehensive hardware(More)
—Interest in using Mobile Cloud Computing (MCC) for compute intensive mobile devices jobs such as multimedia applications has been growing. In fact, many new research efforts were invested to maximize the mobile intensive jobs offloading to the cloud within the cloud system coverage area. However, a large scale MCC deployment challenges and limitations are(More)
The increasing importance of security in computers and communication systems introduces the need for several public-key cryptosystems. The modular division and multiplication arithmetic operations in GF (p) and GF (2 n) are extensively used in many public key cryptosystems, such as El-Gamal cryptosystem, Elliptic Curve Cryptography (ECC), and the Elliptic(More)
This paper presents a processor architecture for elliptic curve cryptography computations over GF(p). The speed to compute the Elliptic-curve point multiplication over the prime fields GF(p) is increased by using the maximum degree of parallelism, and by carefully selecting the most appropriate coordinates system. The proposed Elliptic Curve processor is(More)
