“…However, Wang et al have shown that this scheme can be easily broken by using Parseval's theorem [17] . Recently, Almulla et al proposed a key exchange protocol where the platform group is a set of m commuting square singular matrices of dimension n × n over a finite field [18] . Almulla's scheme uses similar technique, in terms of the compositions of functions, as suggested in Ref [16], the selected set of square singular matrices instead of functions makes the scheme secure against various cryptanalytic attacks including that proposed in Ref [17].…”

“…Almulla et al . propose a cryptographic protocol for symmetric key exchange based on a set of m commutative square singular matrices of dimension n × n . The suggested scheme provides a concurrent technique for users of symmetric‐key cipher systems to securely exchange their private keys over public channels.…”

EDITORIALSpecial Issue: Performance evaluation of communications in distributed systems and Web based service architectures Taha et al. [1] evaluate the consequence of choosing a frame structure type in Worldwide Interoperability for Microwave Access (WiMAX) networks based non-transparent relay stations (ntRS).In the IEEE (Institute of Electrical and Electronics Engineers) 802.16j-2009 protocol, two frame structure types are possible: single frame and multi frame. From performance evaluation point of view, a comparison has never been investigated. The authors suggest to expand on Light WiMAX ns2 add-on to support ntRS, the two frame structure types, in addition to the relevant operational requirements [e.g., quality of service (QoS)]. They show that the multi-frame structure allows higher throughput and voice capacities whereas the single frame shows some general advantage in terms of delay.De Grandia et al.[2] focus on the extension of the high level architecture (HLA) standard with balancing techniques to be used during simulation. The authors studied some balancing approaches to provide a sub-optimal solution for the imbalance issues. But, these approaches are limited to some simulation aspects. Also, a hierarchical balancing scheme was proposed that presents several drawbacks that are related to the centralization of the core part of the scheme, the redistribution algorithm, which is susceptible to bottlenecks, overheads, global synchronization, and single point of failure. Therefore, a scheme based on a distributed algorithm to rearrange the computational and communication load dynamically is proposed. Experiments have been performed to evaluate the effectiveness of the distributed scheme when compared with the scheme based on a centralized redistribution algorithm. The experimental results show that the distributed balancing technique can provide balancing efficiency similar to the centralized technique or even improve the performance gain for some specific cases. Gidenstam et al. [3] propose the cluster consistency model that bridges the gap between traditional and current approaches in supporting both scalability and ordered event delivery. The study introduces a dynamic and fault tolerant cluster management method that can coordinate concurrent access to resources in a peer-to-peer system and can be used to establish fault-tolerant configurable cluster consistency with predictable reliability, running on top of decentralized probabilistic protocols supporting scalable group communication. This paper provides analytical and experimental evaluation of the properties regarding the fault tolerance of the approach.Anderson [4] shows that the combination of various methods for information research significantly enhance the search results. The author explores context data, using query enhancement techniques, and appropriately fusing the results to provide the best ordering when presenting the results to the user. Context data includes a users personal calendar, location, preferences, personal vocabulary, and...
