MANET环境下的密钥预共享安全引导模型
Security bootstrapping model of key pre-sharing in MANET
摘要
Abstract
Key pre-sharing model based on one-way hash function and （t,n） threshold schema of La- grange polynomial group was proposed to implement the security bootstrapping in mobile Ad hoc net- works （MANET） environment. This model involved following two phases, including the pre-sharing keys based on one way hash function and＇I Lagrange interpolation polynomial group, and recovering the secure key based on the digital signature of threshold schema. The one way hash approach can effec- tively prevent the splitted key pieces in a key pool from being exposed. The digital signature of threshold schema also has advantages to detect and block the DoS attack and other malicious fraudu- lent behaviors during the processes of key reconstruction and recovery. The experiments of simulated environment were performed to validate the approach on the performance of successful establishing se- cure link, computation complexity, the security of bootstrapping process, the capability of network recovery from compromised nodes, and the network scale etc. The simulated experimental results show that this approach can harden the security of MANET environment with better performance.关键词
