SPINS -Security Protocol For Sensor Network
Abstract
Wireless sensor networks will be widely deployed in the near future. Many researched are doing on making these networks feasible and useful. Sensor networks are identified as being useful in different domains to include battlefield and perimeter defense. So we have to give high attention to security.
A suite of security protocols optimized for sensor networks: SPINS. SPINS has two secure building blocks: SNEP and _TESLA. SNEP the following important baseline security primitives: data confidentiality, two-party data authentication, and evidence of data freshness. Providing efficient broadcast authentication, which is an important mechanism for sensor networks is a hard problem._TESLA provides authenticated broadcast for severely resource-constrained environments.
