In dynamic and decentralized environments such as ad hoc networks, ensuring secure communication and mutual trust among nodes presents a significant challenge due to the absence of centralized control and frequent topology changes. This paper proposes a Trust-Aware Security Framework that integrates Random Bit Operations with the RC4 Stream Cipher to enhance confidentiality, authenticity, and trustworthiness in node-to-node communication. The proposed model employs random bit manipulation during the key generation and encryption phases to increase entropy and resist statistical and correlation attacks typically associated with traditional RC4 implementations.
