As agent technology is expected to become a possible base platform for an electronic services framework, especially in the area of Electronic Commerce, reliable security protection is a crucial aspect, since some transactions in this area might involve confidential information, such as credit card number, bank account information or some form of digital cash, that has value and might therefore be attacked. In addition, without proper and reliable security protection, the wide spread use of agent technology in real world applications could be impeded. In this paper, evaluation of the Recorded State Mechanism (RSM) previously proposed by the authors is presented. The evaluation examines the RSM security protection and implementation overhead, in order to analyse the RSM security strength and implementation feasibility in real world application.
A variety of group communications has been developed, and over recent years there has been increasing standardisation in communications to improve interconnectivity and provide a common flexible infrastructure in a wide spread communication network. This infrastructure is provided within the Open System Interconnection (OSI) environment. Within OSI the X. 400 series of recommendations provide standard protocols and message formats that allow exchange of messages on a global basis.Modelling of group activities within three application groups provide three sets of services and tools for a wide range of group communication activitities. The services and tools identified for group editing activities may be viewed in an OSI environment by defining a separate application type
With the advent of agent technology, the need for security of applications becomes a concern that is beyond classical data security capability and considerations. Without proper security protection especially against a malicious host attack, the widespread use of agent technology can be severely impeded. The Random Sequence 3-level obfuscated algorithm has been proposed by the authors to improve agent security: in this paper, an enhancement to the protection level of this algorithm is proposed. The effectiveness of the obfuscation algorithm is enhanced by addition of noise, which surrounds the true value carried by the agent with false values. A malicious host can thus at best guess the true value carried by the agent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
