Lossy Trapdoor Functions (LTDFs), introduced by Peikert and Waters (STOC 2008) have been useful for building many cryptographic primitives. In particular, by using an LTDF that los...
In this paper, we propose a multi-signature scheme, in which each signer can express her intention associating with the message to be signed. Signers' intentions mean a kind o...
Generalized signcryption which proposed by Han is a new cryptographic primitive which can work as an encryption scheme, a signature scheme or a signcryption scheme [5]. However,the...
An object encoding translates a language with object primitives to one without. Similarly, a class encoding translates classes into other primitives. Both are important theoretica...
Abstract. Web services are an important series of industry standards for adding semantics to web-based and XML-based communication, in particular among enterprises. Like the entire...
