A Pollard-like pseudorandom number generator over EC
In this short paper we propose a pseudorandom number generator over EC based on Pollardlike method. In contrast to the well known Elliptic Curve Random Number Generator (see e.g. ANSI and NIST draft standards) the generator is based on a random walk over the group of EC-points like in the original Pollard’s rho algorithm and only resembles a little bit the linear congruential generator over ell...
متن کاملEfficient 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 کاملData Security Analysis and Security Extension for Smart Cards Using Java Card
Smart cards improve the convenience and security of any transaction. They provide tamper-proof storage of user and account identity. Multifunction cards are used to manage network system access, store value and other data. The cards carry personal account, credit and buying-preference information and thus, security becomes a primary issue here. Public Key Cryptography plays an essential role in...
متن کاملSecure Elliptic Curve Implementations: An Analysis of Resistance to Power-Attacks in a DSP Processor
With the popularity of wireless communication devices a growing new important dimension of embedded systems design is that of security. This paper presents exploration of power attack resistance, using a statistical approach for identifying regions of the power trace which pose a possible security threat. Unlike previous power analysis research, a new metric supporting small timing shifts and c...
متن کاملImplementing an efficient elliptic curve cryptosystem over GF(p) on a smart card
Elliptic curve cryptosystems (eccs) are becoming more popular because of the reduced number of key bits required in comparison to other cryptosystems (for example, a 160 bit ecc has roughly the same security as 1024 bit rsa). Eccs are especially suited to smart cards because of the limited memory and computational power available on these devices. ∗Information Security Research Centre, Queensla...
