A dynamic password authentication scheme based on public-key concept is proposed in this paper. The login password is changed dynamically and users can use this scheme within a remote login environment. Since we emplo...

In this paper, we present parallel bundle-based decomposition algorithms to solve a class of structured large-scale convex optimization problems. An example in this class of problems is the block-angular linear progra...
Peer-to-Peer (P2P) networks organize large amounts of resources distributed across the Internet for user access. However, the availability of these resources is hindered by the participants' transient connectivity...

Distributed storage systems frequently use erasure coding based redundancy or replication to improve availability. Traditional erasure coding based approaches to redundancy are optimal in terms of their storage overhe...

Carmenisch et al. proposed a blind signature scheme based on the discrete logarithm during at the rump session of Eurocrypt'94. Horster er al. generalised this approach to design the Meta blind signature schemes. The author of this letters points out that these schemes cannot provide true blind signatures.
Masquerading and eavesdropping are major threats to the security of wireless communications. To provide proper protection for the communication of the wireless link, contents of the communication should be enciphered ...

In this paper we study permutation routing techniques for all-optical networks. Firstly, we show some lower bounds on the number of wavelengths needed for implementing any permutation on an alloptical network in terms...

Open Systems Interconnection (OSI) enables communication between computers using a common set of protocols (rules) and structured data [5,9]. ASN.1 (Abstract Syntax Notation One) is a formal notation allowing communic...

- This paper presents an adaptive QoS management scheme to accommodate dynamic variations in network resources, due to the mobility of the users and location-dependent errors. The scheme ensures that satisfactory leve...

With ISDN user part (ISUP) signalling, it will be possible to provide different services in the same transmission facility without dedicated partitioning. We consider here a multi-service switched integrated digital n...
