A semantic-aware role-based access control model for pervasive computing environments

A. Javadi; M. Amini

Volume 5, Issue 2 , July 2013, Pages 119-140


  Access control in open and dynamic Pervasive Computing Environments (PCEs) is a very complex mechanism and encompasses various new requirements. In fact, in such environments, context information should be used in access control decision process; however, it is not applicable to gather all context information ...  Read More

GTrust: a group based trust model

M. Ezhei; B. Tork Ladani

Volume 5, Issue 2 , July 2013, Pages 155-170


  Nowadays, the growth of virtual environments such as virtual organizations, social networks, and ubiquitous computing, has led to the adoption of trust concept. One of the methods of making trust in such environments is to use a long-term relationship with a trusted partner. The main problem of this ...  Read More

Prediction of user's trustworthiness in web-based social networks via text mining

H. Mohammadhassanzadeh; H. R. Shahriari

Volume 5, Issue 2 , July 2013, Pages 171-187


  In Social networks, users need a proper estimation of trust in others to be able to initialize reliable relationships. Some trust evaluation mechanisms have been offered, which use direct ratings to calculate or propagate trust values. However, in some web-based social networks where users only have ...  Read More

Convertible limited (multi-) verifier signature: new constructions and applications

S. Avizheh; M. Rajabzadeh Asaar; M. Salmasizadeh

Volume 5, Issue 2 , July 2013, Pages 189-208


  A convertible limited (multi-) verifier signature (CL(M)VS) provides controlled verifiability and preserves the privacy of the signer. Furthermore, limited verifier(s) can designate the signature to a third party or convert it into a publicly verifiable signature upon necessity. In this proposal, we ...  Read More

STLR: a novel danger theory based structural TLR algorithm

R. Azmi; B. Pishgoo

Volume 5, Issue 2 , July 2013, Pages 209-225


  Artificial Immune Systems (AIS) have long been used in the field of computer security and especially in Intrusion Detection systems. Intrusion detection based on AISs falls into two main categories. The first generation of AIS is inspired from adaptive immune reactions but, the second one which is called ...  Read More
