Self-Organizing Key Security Management Algorithm in Socially Aware Networking

In socially aware networking, encryption algorithms are used in privacy-preserving algorithms to provide security for the nodes. However, the shared key lacks certain security management during transmission, which can affect the security of messages delivery. Therefore, this paper proposes a Self-organizing Key Security Management Algorithm (SKSM) to manage the secure transmission of keys used in encryption algorithms in socially aware networking. The key management algorithm comprises three main parts: node authentication protocol, node trust management, and key slice transmission. Firstly, zero-knowledge authentication and trust management are utilized to authenticate and manage the network nodes. Then, threshold cryptographic segmentation of keys is performed for transmission. After the key reaches the threshold, the key is recovered to ensure that the encrypted information will not be leaked or intercepted during transmission. The simulation experimental results demonstrate that the SKSM algorithm, compared with the traditional algorithms more effective than the traditional algorithm in ensuring secure message transmission, improving transmission rates, and reducing average network transmission latency.
