Abstract: In this paper we propose architecture for a Reconfigurable, Adaptive, Fault-Tolerant (RAFT) framework for application in real time systems with require multiple levels of redundancy a
4、nd protection. Typical application environments include distributed processing, fault-tolerant computation, and mission and safety-critical systems. The framework uses Field Programmable Gate Array (FPGA) technologies with on the fly partial programmability achieving reconfiguration of a system comp
5、onent when the existing components fail or to provide extra reliability as required in the specification. The framework proposes the use an array of FPGA devices to implement a system that, after detecting an error caused by a fault, can adaptively reconfigure itself to achieve fault tolerance. The
6、FPGAs that are becoming widely available at a low cost are exploited by defining a system model that allows the system user to define various levels of reliability choices, providing a monitoring layer for the system engineer. ? 2005 IEEE.

9、ided to safely protect the computer by monitoring an interrupt or an event related to file handling and enable a user to perform setting conveniently. CONSTITUTION: A setting list(50) stores permission for changing an executable file. A detecting module(10) detects/intercepts occurrence of the inter
10、rupt or the event related to the file handling. An analysis module(20) checks the permission by comparing the interrupt or the event detected from the detecting module with the setting list after checking that the interrupt or the event is a request for changing the executable file by analyzing the
11、interrupt or the event. A processing module(30) disuses or returns the interrupt or the event depending on an analysis result of the analysis module. 3 Method and system for protecting computer system from malicious software operationPatent number: US2004225877 Publication date: 2004-11-11 Inventor:

18、 data storage or communication peripheral devices without a matching personalized smart card containing a complementary encrypted digital signature. A modified BIOS (Basic Input Output System) replaces the standard BIOS of a motherboard and allows a security engine microprocessor to take over preboo
19、t control of the computer from the motherboard CPU (Central Procesisng Unit), configures and operates the encryption-based security system, and enables or disables selected data storage devices and other user selectable peripherals upon start up and shut down of the computer. The enabling or disabli
20、ng of peripheral devices involves the use of special enabling/disabling circuits. A modified DDL (Device Driver Layer), loaded in the hard drive of the computer as part of the resident O/S (Operating System) of the computer, and memory buffer circuits allows a real time encryption system to be in pl
21、ace for any communication or data storage device. A data encryption engine in the security engine microprocessor allows encryption and decryption of all data stored in data storage devices. Upon power up, reset or interrupt of the computer, the microprocessor looks for, and if present, reads from th
22、e smart card in the smart card reader which is logically connected to the security engine microprocessor. This invention can also be used to allow identification and authentication of the computer and its user in networks. 5 Temporarily authorizing the use of a computer programme protected by an ele
