Innovative Ubiquitous Cryptography and Sophisticated Implementation

Contemporary ubiquitous network has a double-edged sword or alternative aspects, diversity and threat. While worldwide diversity of ubiquitous platforms has really contributed to enhancing the amenity of our daily life, it is also the cause of illegal attack, intrusion, pretension, etc. Current provisions for information security do not always fulfill overall demands required to ever-growing ubiquitous community. In order to keep usability and achieve safety, we have exploited ubiquitous cryptography named RAC (random number-addressing cryptography). This is an innovative common key technique and has more promising performance than block cipher like DES and AES. Although RAC can be run on any platform, a dedicated processor is more preferable in order to achieve sufficient speed, performance, and strength in the cryptographic streaming of large quantity of ubiquitous information. In order to distinguish these features without deteriorating media processing, we have developed a ubiquitous processor named HCgorilla and its software support. It is a single chip multimedia mobile processor unified sophisticated features of RAC and processor techniques useful for low power, high throughput, and Java. The system combined HCgorilla and the software support works well for media processing as well as ubiquitous cryptography
