Hangout for experimental confirmation and demonstration of software, computing, and networking. The exercises don't always work out. The professor is a bumbler and the laboratory assistant is a skanky dufus.

2005-07-02Is Distributed Trustworthiness Soup Yet?ACM News Service: T-Engine – Japan’s Ubiquitous Computing Architecture Is Ready for Prime Time. Out of Japan’s T-Engine Forum arrives a scaled hardware/software platform for ubiquitous computing. T-Engines scale from standard (phone and PIM sized) through Micro (home appliances) to Nano (small electronics) to Pico (valves, switches, maybe smart RFIDs). The promises of the standardized and licensed family include software resource distribution and tamper-proof network security. The T-Kernel operating system is a carefully standardized and normalized derivative of ITRON, a real-time embedded-system OS in turn based on the TRON Project (including eTRON security, based on a secure digital-entity and identity scheme). Although there is reference to an open-source T-Kernel, the license for the source code is compatible with neither the GPL nor the broader Open Source Definition. Redistribution is seriously constrained in favor of preserving code reusability atop T-Kernel implementations. What caught my eye in the blurb is the reliance on ucode, a tagging system that appears to rely on a centralized database system of the Ubiquitous ID (UID) Center and Ubiquitous Communicator functions. There are documents on uID and its relationship with eTRON worthy of exploring further. I tend to seek decentralized distributed systems, such as P2P overlays, that provide some degree of secure entity identification. I am not sure this model fits, though it certainly works with product identification in the manner of RFID tagging. Jan Krikke’s June 2005 IEEE Pervasive Computing article on the subject is available on-line as a downloadable PDF [one that seems to crash Acrobat on my computer]. {tags: uID identity TRON T-engine Sakamura HonorTagPersonal} |
