Because publishers and subscribers are not tightly coupled, achieving the fundamental security mechanism in a publish/subscribe system is extremely difficult. Through the adaptation of pairing-based cryptography, this paper presents a novel approach to provide confidentiality and authentications in a broker-less content-based publish/subscribe system. Additionally, it employs a lightweight encryption scheme, P-Coding, to provide confidentiality in an energy-efficient manner. Additionally, this article maintains the publish/subscribe system's weak subscription confidentiality. The overall method offers fine-grained key management, and the order of subscription attributes determines the cost of encryption, decryption, and routing. It lowers the energy that data encryption uses.
