VoIP is replacing traditional telephony system over PSTN as a more affordable communication tool on account of convergence of networks. Meanwhile, security issue brings more attention and becomes more important. SIP is based on text message. This makes the protocol easy to implement but also creates opportunity for hackers to steal or modify the messages. There exist a various approaches to secure...
Security is an important concern in Voice over IP (VoIP) applications. An approach to securing the signaling, such as the Session Initiation Protocol (SIP) and Location to Service Translation (LoST) messages, is to use Transport Layer Security (TLS). Several studies have measured the impact of using TLS on SIP. However, there have not been any tests on the impact of TLS or Internet Protocol Security...
The IPv6 protocol is the next-generation IP protocol that addresses many of the shortcomings that exist in the IPv4 protocol. Some of the enhancements include increased address space, mandatory security and provisioning of stateless auto-configuration, a technique through which a new node forms its own address without the assistance of centralized host configuration servers operating in the network...
In recent years high performance computing has evolved from large and expensive supercomputers to network based environments or workstation clusters and to grid computing. A grid is composed by geographically sparse resources that join to form a virtual computer. The resources (computers, networks, storage devices, etc.) of the grid are heterogeneous and reside in differentiated domains. An important...
Reliable Server Pooling (RSerPool) denotes the new IETF standard for a lightweight server redundancy and session failover framework for availability-critical applications. A number of research papers have already addressed the service and pool management performance of RSerPool in general. However, the important topic of security, including the system robustness against intentional attacks, has not...
Business-to-business (B2B) and Business-to-consumer (B2C) transactions in public domains such as Internet require secure communications mechanisms and, especially for applications accessible through web browsers, the secure socket layer (SSL) protocol is one of the most viable solutions to provide the required level of confidentiality, message integrity and endpoint authentication. The two main alternatives...
Nowadays, Internet has become the common media of communication. Many group communication applications can easily be conducted on the Internet. Some group communication applications pose strict requirement that in case of network partitions or on each join/leave event, a group key establishment protocol should not execute itself afresh. Although many group key establishment protocols have been proposed...
Although Dynamic Host Configuration Protocol for IPv6 (DHCPv6) protocol was defined in 2003, it was designed as a framework rather than a complete solution to the automatic configuration in IPv6 networks. There are still some unsolved problems and new options yet to be defined. One example of such case is Fully Qualified Domain Name (FQDN) option, which final version has been published in late 2007...
