Elliptic curve cryptosystems are suitable for memory-constraint devices like wireless network due to their small key-size. A novel approach is proposed to speed up the pre-computation stage of window-w nonadjacent form elliptic curve scalar multiplication by conjugate additions and strategic points. Our analysis shows that the proposed scheme offers lower costs than other known methods for various...
In pervasive computing environment privacy concerns should be taken into account. A anonymous routing protocol is presented, which preserves the IP address of users and keep their communication anonymous. The protocol can conceal the source and destination IP address in order to protect them. Yet users will still be able to communicate with other entities. Moreover the protocol can resist denial of...
