Abstract. One important problem for such public broadcast LBS is to enforce access control on a large number of subscribers. In such a system a user typically subscribes to a LBS f...
Public-key cryptosystem (PKC) is one of inevitable key technologies in order to accomplish fruitful security applications in ubiquitous computing systems. The ubiquitous computer o...

Abstract. We present efficient compression algorithms for subgroups of multiplicative groups of finite fields, we use our compression algorithms to construct efficient public key c...
Public Key technology is about multiple parties across different domains making assertions that can be chained together to make trust judgments. Today, the need for more interoper...
Combinatorial problems serve as an important resource for developing practical public key cryptosystems and several combinatorial cryptosystems have been proposed in the cryptograp...
