It is sometimes argued (as in [6]) that finding meaningful hash collisions might prove difficult. We show that at least one of the arguments involved is wrong, by showing that for...
In this paper, we investigate the gap between auxiliary-input zero-knowledge (AIZK) and blackbox-simulation zero-knowledge (BSZK). It is an interesting open problem whether or not ...
In an open network such as the Internet, multicast security services typically start with group session-key distribution. Considering scalability for group communication among wide...
With the phenomenal growth of the Internet and open networks in general, security services, such as non-repudiation, become crucial to many applications. Nonrepudiation services m...
The growth of the Internet opens up tremendous opportunities for cooperative computation, where the answer depends on the private inputs of separate entities. Sometimes these comp...
