Oriented Cloud Computing Performance And Power Consumption Can Be Configured The Security Terminal Technology Research

Along with concept of the "Cloud Computing", Cloud computing and its relative applications has achieved vigorous development. The key thought of the cloud computing is that a good deal of computing resource connected by network is managed and dispatched uniformly by provider, and distribute the computing resource according to users' demand. Based on this thought, cloud computing-oriented security terminals must have the ability to encrypt and decrypt massive data. In addition, current safe cryptography intensity confronts a big challenge because of the strong computing ability of cloud. The cloud computing-oriented termainals need to improve the current security intensity for various cryptography algorithms, and increase the key-length, which demands the high-level security calcation for terminals. What's more, as a terminal, especial for a mobile one, power comsuption is very important factor in the design except for the performance requirement. Security terminals must try to reduce the power consumption to extend the working hours.Based on the analysis of cloud computing-oriented terminals requirements, our paper proposes a high efficiency hardware design to support the demands of the security terminals. Firstly, we propose a security domain application specific instruction set processor (ASIP), and based on this ASIP, we give an extended VLIW AS IP, SophSEC, with high performance, and it can support three main types of ciphters, symmetric-key algorithms, hash functions, and public-key algorithms. At the same time, we analyze the characteristic of popular multi-core platform:the SoC based on system bus and NoC Platform, and present the hardware design of high efficienty SoC and NoC platform. Here, SoC Platform integrates MIPS, PP and multiple SophSEC, and cores are connected by AMBATM AHB Bus. The SoC Platfomr is used for minitype terminals with reasonable performance and low area cost or power consumption, such as handheld and mobile terminals. And NoC Platfomr integrates multiple MIPSs and SophSECs, and achieves high performance of cryptography algorithms. This platform is used for large-scale terminals, such as domestic gateway or wireless AP.In order to verify the proposed security terminals, the proposed cryptography ASIP, SophSEC, and SoC Platform are implemented into chip by the SMIC 0.13μm standard CMOS technology, and the NoC array is also synthesized by Mentor's Veloce Solo Emulater and Design Compiler. The testing results indicates that, the SoC platform area is 321.5K equivalent XOR gates, the throughput are 564Mbps, 212Mbps,256Mbps,19Kbpså'Œ131Mbps for AES-128, SMS4, SHA-1, RSA-1024 and CCMP respectively, and the chip's power consumption is 325mW@100M Hz。The NoC area is 3.08M gates, and the throughtput are 3.54Gbps,2.08Gbps,1.64Gbps, and 66.7Kbps for AES-128, SMS4, SHA-1, RSA-1024 respectively。Both platform achieve the target of performance, area and power consumption, and have the ability to support the encryption and decryption for massive data, and has the advantage of performance & power scalability and easy to extend. Our proposed Platforms are very suitable for the cloud computing-oriented security terminal, and also have a good prospective for applications.
