5G时代为物联网高速发展带来了机遇,身份认证是保障物联网安全的基础。然而在面对量子攻击时,由于物联网节点众多,基于签密的身份认证方案生成节点密钥将消耗大量资源,难以满足物联网低开销的需求。为此,设计了一种基于格的轻量级群签密认证方案。在密钥生成阶段,设计了改进陷门对角矩阵,优化生成密钥所需的原像采样算法,减小了生成大量密钥时所需的整体时间;在身份认证阶段,基于剩余哈希引理和签密性质,在一个逻辑步骤内对消息同时进行签名和加密,提出了低次数的点乘与哈希运算的交互流程,完成组长代替群组成员进行的接入认证。仿真实验表明,该方案降低了物联网设备接入时的交互次数,减少了身份认证阶段的计算开销,对比现有方案,签密与解签密的总开销降低了至少7%,同时证明了该方案能在物联网中抵抗量子攻击。
The 5G era has brought opportunities for the rapid development of the Internet of things. Identity authentication is the basis for ensuring the security of the Internet of things. However
in the face of quantum attacks due to the large number of nodes in the Internet of things
the signcrypt-based identity authentication scheme will consume a lot of resources to generate node keys
which is difficult to meet the low cost requirements of the Internet of things. Therefore
a lightweight lattice-based group signcryption authentication scheme was designed. In the key generation stage
the improved trapdoor diagonal matrix was designed to optimize the original image sampling algorithm required for key generation and reduce the overall time required for generating a large number of keys. In the identity authentication stage
based on the residual Hash lemma and the signcryptic property
the message was signed and encrypted in one logical step at the same time
and the interaction flow of dot multiplication and Hash operation with low frequency was proposed to complete the access authentication performed by the group leader on behalf of the group members. Simulation experiments show that this scheme reduces the number of interactions during the access of Internet of things devices
reduces the computing cost of identity authentication stage
and reduces the total cost of signcryption and decryption by more than 7% compared with the existing schemes. Furthermore
the simulation results prove that this scheme can resist quantum attacks in the Internet of things.
