摘　　要：在计算机网络安全领域,数据完整性、隐私保护和对抗网络威胁至关重要。传统的代理重加密(Proxy Re-Encryption,PRE)技术在处理大批量数据时面临延迟和计算强度大等问题。为解决这些问题,提出一种创新的T-PRE(Trim Proxy Re-Encryption)方案。该方案通过集成轻量级对称和非对称密码技术,优化了PRE效率,降低了计算成本,并节省了资源受限节点的计算资源。此外,设计了一套复杂的密钥管理和数字证书机制,确保了密钥生成、节点认证和数据共享的安全性。T-PRE方案将重新加密任务委托给簇头,增强了数据的隐私性和完整性。验证结果表明,该方案显著提高了网络的安全性和传输效率。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.
