It is widely recognized that security issues will play a crucial role in the majority of future computer and communication systems. Central tools for achieving system security are...
Consider an electronic election scheme implemented using a mix-net; a large number of voters submit their votes and then a smaller number of servers compute the result. The mix-net...
We investigate public key encryption that allows the originator of a ciphertext to retrieve a “forgotten” plaintext from the ciphertext. This type of public key encryption wit...
Local monitoring is an effective mechanism for the security of wireless sensor networks (WSNs). Existing schemes assume the existence of sufficient number of active nodes to carry...
The notion of concurrent signatures was recently introduced by Chen, Kudla and Paterson. In concurrent signature schemes, two entities can produce two signatures that are not bindi...
