Abstract

In the field of computer network security, data integrity, privacy protection, and countering network threats are crucial. The traditional Proxy Re-Encryption (PRE) technology faces problems such as delay and high computational intensity when processing large quantities of data. In order to solve these problems, an innovative T-PRE (Trim Proxy Re-Encryption) scheme is proposed. By integrating lightweight symmetric and asymmetric cryptographic techniques, the scheme optimizes the PRE efficiency, reduces the computing cost, and saves the computing resources of resource-constrained nodes. In addition, a set of complex mechanisms for key management and digital certificates is designed to ensure the security of key generation, node authentication, and data sharing. The T-PRE scheme delegates the re-encryption tasks to the cluster heads, enhancing the privacy and integrity of the data. The verification results show that the scheme significantly improves the security and transmission efficiency of the network.
