ID-based sensor node authentication for multi-layer sensor networks

摘要: Despite several years of intense research, the security and cryptography in wireless sensor networks still have a number ongoing problems. This paper describes how identificatio n (ID)- based node authentication can be used to solve key agreement problem three-layer interaction. The scheme uses novel se- curity mechanism that considers characteristics, architecture, vulnerability sensors, provides an ID-based does not require expensive certificate s. routing process using simple ID suit- able for low power exposure, proposes authentication. method achieves low-cost communica- tions with efficient protocol. Results from this study dem on- strates it improves performance under different densities, reduces computational cost encryption decryption.
