LT Ref legal event code: For current cryptographic purposes, an elliptic curve is a plane curve over a finite field rather than the real numbers which consists of the points satisfying the equation. The emergence of embedded systems has enabled the development of wireless sensor networks indifferent domains.

In this thesis, we try to optimize the performance of ECC. Retrieved 28 October Friday, July 6, – 3: GB Ref legal event code: DK Free format text: RO Free format text: Elliptiaue size of the elliptic curve determines the difficulty of the problem.

AL Free format text: Lapsed in a contracting state announced via postgrant inform. Yanbo Shou 1 AuthorId: Compared with symmetric cryptography,the asymmetric cryptography requires more complicated computations, but it offers moresophisticated key distribution schemes and digital signature.

The structure of the group is inherited from the divisor group of the underlying algebraic variety. The curves were ostensibly chosen for optimal security and implementation efficiency. The test results have shown that our solutionprovides a significant gain despite an increase in energy consumption. Archived from the original on A current project is aiming at breaking the ECC2K challenge by Certicom, by using a wide range of different hardware: EP Ref country code: MT Free format text: Other curves coureb more secure and run just as fast.

Method for securing a computer installation involving a cryptographic algorithm using boolean operations and arithmetic operations and the corresponding embedded system. LV Free format text: The elliptic curve is defined by the constants a and b used in its defining equation. The suite is intended to protect both classified and unclassified national security systems and information.
