Abstract:Mobile agent paradigmatics has become driving force for recent advances in distributed systems. The advent of mobile agency raises major security problems. The authors identified five fundamental cryptographic limitations of mobile agents: integrity; availability; confidentiality; authentication; and non-repudiation. Methodologies employed in this research that form basis for design of Secure Enhanced Mobile Agent Security Architecture (SEMASA) to advance on existing security mechanism in Marikkannu et al.(2011) are: literature review, object orientation and experimentation. Our proposed architecture employs code obfuscation, cryptography, third party trusted, digital signature, proxy signer and trip marker to achieve mobile code integrity and computation results’ confidentiality. We developed Secure Employees’ Attendance Mobile Agent (SEAMA) to implement our proposed security architecture using visual C-Sharp (C#) and .NET framework in Microsoft’s visual studio. SEAMA was installed on one of three networked computers, and SEAMA was launched to travel from its computer with its data to compute employees’ attendance work history on the two other computers having Microsoft SQL servers and malicious server administrator was programmed to carryout malicious attacks on SEAMA for experimentation, observation and ratiocination. It was discovered that our proposed architecture is immune to most attacks whereas, existing protocol of Marikkannu et al. (2011) could only detect and partially prevent some attacks but not immune to attacks like integrity and confidentiality attacks. Comparative computation shows 22.73% improvement of our scheme over existing protocol. Indubitably, our proposed security scheme can successfully detect and prevent malicious host attacks more than the existing protocol. We recommend that new security techniques could be added in our architecture to improve efficiency of the entire framework.
