A Flexible Role Based Secure Messaging System: An Information System Perspective

In this research, we presented the construction of a flexible role-based secure managing service system which can operate in an open environment. The tool is aimed at providing protection of messages across domains, and caters to most of the commercial requirements for information integrity. The challenge of an unsecure messaging system was addressed by the construction of a flexible secure messaging service system, where role-based messaging and access control and messaging/permissions are managed based on roles, while authorization and encryption (cipher) keys are sent to registered phone numbers. The Software Development Life Cycle was adopted to carry out a detailed study of the existing mailing service systems and role-based messaging systems with a view to identifying the problems and loopholes in the secure role-based mailing system. Analysis and design of the new system were performed using popular software design tools. This study also contributes to providing security features based on architecture design, and demonstrates the implementation of information confidentiality and privacy.
