Extended Role Based Access Control and Procedural Restrictionsontrol of trusted operating systems can discriminate attack trials from normal behaviors. Also, extended RBAC keeps the principle of least privilege and separation of duty more precisely. This paper shows the specification of the extended concept and model, and presents simple analysis results.

Sealed-Bid Auctions with Efficient Bids0 bits (i.e. about 1,000,000 bid prices). This paper proposes the sealed-bid auction protocols based on the efficient MPC protocols, where a?bidder can submit only a?single ciphertext. The bidder’s cost is a?few multi-exponentiations, and thus the proposed protocols are suitable for mobile bidders.

On the Security of a?Group Signature Scheme with Forward Security a?dispute, however, a?designated group manager can reveal the signer of a?valid group signature. Based on Song’s forward-secure group signature schemes, Zhang, Wu, and Wang proposed a?new group signature scheme with forward security at ICICS 2003. Their scheme is very efficient on both communicatio
