The presentation layer of hypermedia systems could benefit from standard object querying functionality and this is most effective if strong typing is enforced. By strong typing we...
This paper describes a new public-key cryptosystem based on the hardness of computing higher residues modulo a composite RSA integer. We introduce two versions of our scheme, one d...
