基于扩展DNA模型的对密钥预分发方案
Pair-wise Key Pre-distribution Scheme Based on Extended DNA Model
摘要
Abstract
A DNA model based pair-wise key establishment scheme is analyzed and the result shows that the resilience of the scheme is poor. Combining DNA model with the idea of multiple key pool, an extended DNA model based pair-wise key establishment scheme is proposed. The gray degree of the variable is changed form 2 to ω. The nodes select multi-DN A strands as its key ring and use the code of some oligonucleotide in some DNA strand as their actual pair-wise key. The key connectivity, security and overhead of the scheme are discussed. The analysis shows that the overhead of computation and communication of the new scheme is little and the security is greatly improved compared with the original DNA model scheme.关键词
