VLSI implementation with double cipher and media processing for ad-hoc network

Ubiquitous network is really one of remarkable trends of next generation information and communication technologies. However, the rapid increase of ubiquitous technologies has given rise to serious concerns about power dissipation and security issues which are getting worse, especially in the case of ad-hoc network because it is resource constrained. The authors have so far developed a ubiquitous processor named HCgorilla. This has unified basic aspects of PC processors, mobile processors, Java CPUs, cryptography processors, etc. The unification of these has been effective to achieve power consciousness and secureness for ubiquitous environment. Considering the increased demand for Green IT in recent years, the target of this study is the further improvement of HCgorilla chips with particular emphasis on low resource and secure implementations. The improved HCgorilla is implemented in a CMOS standard cell chip. Specific features of the HCgorilla chip are also described.
