This paper presents a high-throughput GCM VLSI architecture fully compliant to IEEE 802.1ae applications, which can be operated in all modes specified in the standard. Unlike previous works, with the modified parallel GHASH module, the design implements encryption efficiently without knowing the total number of data blocks in advance. Furthermore, a fully subpipelined version of loop-free key expansion...
Elliptic curve cryptography (ECC) plays an important role in todaypsilas public key based security systems. Compared with the conventional systems such as RSA, ECC delivers much higher security strength per bit. The implementation of ECC lies in three levels: scalar multiplication, point addition/doubling and finite field modular arithmetic. In this paper, we present a novel fast architecture for...
Identity based cryptography (IBC) offers many security advantages over the conventional public key alternative. In the IBC, the bilinear pairing on elliptic curve accounts for the core operation. Such pairing operations are very complicated and slow for software realizations. Therefore, the dedicated hardware implementations and efficient architectures are desirable. In this paper, the Tate pairing...
