A new and high-efficiency encryption and authentication algorithm, SMS4-GCM, based on cryptographic algorithm SMS4 and block cipher operating mode GCM is proposed. Design using full pipeline architecture and implementation on FPGA are presented in detail, and the results show that the maximal processing rate of SMS4-GCM can reach up to 22.248 Gbps which can meet the demands of high-speed network's...
Ghash is the authentication function of GCM. In this paper, we propose a high performance pipelined architecture of Ghash. The pipelined architecture can boost the operating frequency of the hash function block that is the bottleneck for higher speed GCM hardware. The most attractive feature is our pipelined architecture based on divided-and-conquer algorithm. According to the architecture, the critical...
10G EPON can provide us with wide band access technology and high data transmission rate. However, it is faced with a series of security threats due to its point-to-multipoint network topology and high-speed data rate. In this paper, we propose a security mechanism based on GCM (Galois/Counter Mode) for 10G EPON systems, which can support encryption and authentication functions simultaneously. First...
GMAC (Galois Message Authentication Code) is a special case of authenticated encryption mode GCM (Galois/Counter Mode) when it acts as a stand-alone MAC. As the hash function of GMAC, Ghash is based on the GF(2128) multiplier. It is the algebraic properties of Ghash that support incremental authentication of GMAC. In this paper, an efficient hardware implementation on Xilinx Virtex 5 FPGA platform,...
