摘要
采用椭圆曲线上Weil配对的双线性性质,提出了一种基于ID的密钥管理方案。该方案利用密钥生成中心(KGC)与密钥因子组合中心(KGCC)共同完成密钥托管与密钥的生成,避免了传统方案由单个独立的KGC进行密钥管理所产生的安全隐患,KGCC采用种子公钥和密钥映射技术,极大地减轻了存储负担,提高了系统的安全性。经分析表明,该方案比传统方案更高效、轻量、安全、抗攻击能力更强。
An ID based key management scheme based on the bilinear property of Weil pairing defend on elliptic curve was proposed. The scheme used Key Generation Center （ KGC） and Key Gene Combination Center （KGCC） to accomplish key management and generation. To avoid security problems caused by single independent key management, KGCC used seeded public key and private key mapping technology to mitigate the load of storage and improve the security of system. The analysis shows that this scheme is more efficient, lightweight, secure and stronger in anti-attack than traditional scheme.
