For an integer w ≥ 2, a radix 2 representation is called a width-w nonadjacent form (w-NAF, for short) if each nonzero digit is an odd integer with absolute value less than 2w−...
: Access control in sensor networks is used to authorise and grant users the right to access the network and data collected by sensors. Different users have different access right ...
This paper describes an efficient arithmetic processor for elliptic curve cryptography. The proposed processor consists of special architectural components, the most important of...
The use of elliptic curves in cryptography relies on the ability to count the number of points on a given curve. Before 1999, the SEA algorithm was the only efficient method known ...
Embedded devices implementing cryptographic services are the result of a trade-off between cost, performance and security. Aside from flaws in the protocols and the algorithms us...
