Innovative Ubiquitous Cryptography and Sophisticated Implementation

Abstract

Contemporary ubiquitous network has a doubleedged 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 numberaddressing 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.

A Stream Cipher Engine for Ad-Hoc Security

“…The cipher transformation due to simple memory access by the output of a built-in RNG is really dedicated for ubiquitous security [4][5]. HCgorilla is a hardware cryptography-embedded multimedia mobile processor unified Java features with RAP [6][7][8]. We have also exploited a hardware cryptography-embedded multimedia mobile system composed of HCgorilla and its software support system [9], [10].…”

Compact FPU Design and Embedding in a Ubiquitous Processor for Multimedia Performance Enhancement

“…The stream cipher by HCgorilla is a common key process called RAC (random number-addressing cryptography) [8]. RAC is neither almighty nor universal, and as such, is neither one and only nor exclusive computer security technique.…”

“…The cryptographic streaming of multimedia data was further described in detail [10]. Then, the cryptographic streaming or ubiquitous cryptography, RAC was exploited in cooperation with the continuous improvement of HCgorilla and the development of its software support [8].…”
