Abstract—Information sharing and integration are being looked upon as the most increasingly adopted methodologies by governments around the world, for solving problems in a broad variety of programs and policy areas. Issues of universal concern such as disease detection and control, terrorism, immigration and border control, illicit drug trafficking, and more demand information sharing, coordination and collaboration amid government agencies within a country and across national boundaries. Several daunting challenges exist towards the development of a competent information sharing protocol. The principal challenge would be the development of a protocol capable of sharing secure information between different government and non-government agencies, with the purpose of streamlining government services. In this paper, we devise an innovative and proficient trust-based information sharing protocol for secure exchange of confidential and top secret information amongst government intelligence agencies across national boundaries using public key cryptography. The proposed protocol makes use of 1) MD5 Algorithm for Data Integrity 2) Public key cryptosystem for Confidentiality and Authentication and 3) A unique and complex mapping function for Agency Identification. Furthermore, the proposed protocol facilitates privacy preserving information sharing with probable restrictions based on the trust level maintained between the communicating agencies. The trust protocol devised ensures secure and stream-lined information sharing among government intelligence agencies to shun ominous activities.
