To achieve high throughput, core count in compute accelerators such as General-Purpose Graphics Processing Units (GPGPUs) increases continuously. The communication demand of these cores boosts the demand for a low-latency packet switched network. As packet latency is mainly composed of per-hop latency, contention latency and serialization latency, a favorable Network-on-Chip (NoC) design should efficiently...
Informatization is the ultimate way out for audit method in China. In order to improve audit quality, the auditee's information system always needs to be restored on the auditors' environment by re-installing them. The kind of audit model brings great pressure to the auditors, not only is the heavy workload at each audit project, but also there is incompatibility problems between different operating...
In the pervasive environment, in order to adapt to dynamic environments and changeable requirements, the architecture reconfiguration has drawn great attention, which includes structural, behavioral, and configuration aspects. Unfortunately, traditional architecture description methods are always static, and as such fail to completely specify the reconfiguration. In this paper, AADL (Architecture...
A novel, intelligent, high performance and universal purpose pole mounted switch controller with embedded operating system is presented in this paper. It is then demonstrated that the performance and specifications of current art pole mounted switch and it's controller can be substantially improved by using state of the art technologies in electrical power, embedded operating systems, sensors and...
Based on the group of SONY Company ICX229AK PAL image sensor chipset, PAL integrative camera with VGA interface is designed in this paper. Using the DSP + FPGA + ASIC architecture, it completes the acquisition of the video signal and display, and achieves key technologies of auto-focusing and auto iris in the FPGA. Some new type practical functions such as four images storage, mouse driver, real-time...
Anonymous authentication is an important feature for trusted computing. Firstly, this paper describes two kinds of authentication model Trusted Computing Group (TCG) proposed -TTP model and DAA model, and then analyses their advantages and disadvantages. Secondly, the paper proposes an improved solution based on the elliptic curve algorithm (ECC) in the base of the original DAA model. Finally, the...
Any endpoint with network connection may be our workbench as new computing models like cloud computing arise. We've designed a protocol to establish the user's trust in public endpoints covering hardware, firmware as well as software components. Three parties are involved for trust establishment: the user with a chip (MTPCM) to actively measure the platform, the endpoint owners who offer the platforms...
In this paper, we propose a formal model of trust chain from the view of measurement structure and remote attestation. Trust chain is an important technology in Trusted Computing and has received considerable attention. However, related researches on trust chain have some deficiencies such as the coarse granularity, single measurement function and ignorance of influence from run-environment when report...
