A high-performance elliptic curve cryptography processor (HP-ECCP) was designed to support five field sizes of 192, 224, 256, 384 and 521 bits over GF(p) defined in NIST FIPS 186-2, and it provides eight modes of arithmetic operations including ECPSM, ECPA, ECPD, MA, MS, MM, MI and MD. In order to make the HP-ECCP resistant to side-channel attacks, a modified left-to-right binary algorithm was used, in which point addition and point doubling operations are uniformly performed regardless of the Hamming weight of private key used for ECPSM. In addition, Karatsuba-Ofman multiplication algorithm (KOMA), Lazy reduction and Nikhilam division algorithms were adopted for designing high-performance modular multiplier that is the core arithmetic block for elliptic curve point operations. The HP-ECCP synthesized using a 180-nm CMOS cell library occupied 620,846 gate equivalents with a clock frequency of 67 MHz, and it was evaluated that an ECPSM with a field size of 256 bits can be computed 2,200 times per second.

USA is strengthening the information sanity by managing federal agency's information and information system systematically. For this purpose, US government put the Federal Information Security Management Act into the E-Government Act of 2002. According to the FISMA, it is required to have information security management plan for ail federal agencies. In addition that, Inspector Generals of these agencies should assess the status of their agency and report the result to the office of Management and Budget. Collecting all the reports from each agency, OMB should report to GAO on general status of information security of federal agency. It is helpful to provoke the information security as a necessary activity to realize the E-government. Comparing these efforts with our system will give us good implications to get more idea to secure our information system.
