This Paper aims to have a comprehensive discussion on identity-based cryptography and aims to have a detail explanation on its technical aspect. Moreover, it discusses on how IBC helped in securing the confidentiality and authenticity of messages in information technology specifically in military services through the mobile ad hoc network (MANET). The paper further talks on the challenges encountered in the utilization of identity-based cryptography in the field of telecommunications and information technology and on the development of new techniques that can strengthen the security and protection of the messaging system in the area of wireless communication.
