The view that academic writing is purely objective, impersonal and informational, which is often reflected in English for Academic Purposes materials, has been criticized by a number of researchers. By now, the view of academic writing as embodying interaction among writers, readers and the academic community as a whole has been established. Following this assumption, the present study focused ...

In this paper, we show how to construct an Identity Based Signcryption Scheme (IBSC) using an Identity Based Encryption (IBE) and an Identity Based Signature (IBS) schemes. This we obtain by first extending the An-Dodis-Rabin construction to the Identity Based setting and then instantiating. We then further modify the construction to obtain an efficient construction. We show that the security o...

We give a generic construction for universal designated-verifier signature schemes from a large class, C, of signature schemes. The resulting schemes are efficient and have two important properties. Firstly, they are provably DV-unforgeable, non-transferable and also non-delegatable. Secondly, the signer and the designated verifier can independently choose their cryptographic settings. We also ...

the concept of identity and its formation is one of the most basic notions in the field of social psychology. many psychologist and sociologists have presented their theories based on this concept and the psychosocial progress of its formation in social contexts. henry tajfel, a prominent social psychologist, in his social identity theory has divided an individual’s identity into two parts: “pe...
