Efficient elliptic curve cryptosystems
Elliptic curve cryptosystems (ECC) are new generations of public key cryptosystems that have a smaller key size for the same level of security. The exponentiation on elliptic curve is the most important operation in ECC, so when the ECC is put into practice, the major problem is how to enhance the speed of the exponentiation. It is thus of great interest to develop algorithms for exponentiation...
متن کاملPower Analysis Attacks and Algorithmic Approaches to their Countermeasures for Koblitz Curve Cryptosystems
Because of their shorter key sizes, cryptosystems based on elliptic curves are being increasingly used in practical applications. A special class of elliptic curves, namely, Koblitz curves, offers an additional but crucial advantage of considerably reduced processing time. In this article, power analysis attacks are applied to cryptosystems that use scalar multiplication on Koblitz curves. Both...
متن کاملElliptic Curve Cryptosystems
We discuss analogs based on elliptic curves over finite fields of public key cryptosystems which use the multiplicative group of a finite field. These elliptic curve cryptosystems may be more secure, because the analog of the discrete logarithm problem on elliptic curves is likely to be harder than the classical discrete logarithm problem, especially over GF(2"). We discuss the question of prim...
متن کاملImplementing Elliptic Curve Cryptosystems
In 1987 Neil Koblitz first suggested the use of Elliptic curves for Public Key Cryptosystems. This has triggered publications about ECC (Elliptic Curve Cryptography) in recent years as well as the appearance of first University textbooks about that topic. Some Mathematicians and Computer Scientists have focused their studies of Elliptic curves on efficiency and security of ECC. Questions arise ...
متن کاملImplementation of Elliptic Curve Cryptosystems
During the last few years, a considerable effort has been devoted to the development of reconfigurable computers, machines that are based on the close interoperation of traditional microprocessors and Field Programmable Gate Arrays (FPGAs). Several prototype machines of this type have been designed, and demonstrated significant speedups compared to conventional workstations for computationally ...
