WSN中基于圆锥曲线组合密钥的对等认证

综合分析了无线传感器网络已有认证协议在加密体系、PKC公钥绑定及应对攻击形式等方面的发展趋势和不足,给出引入了位置信息的基于身份的节点对等认证方案.该方案采用在求逆、求阶及求点倍数等操作比椭圆曲线容易的圆锥曲线加密体系.基于身份避免了证书的颁发/更新、存储、索取、验证等计算和通信开销;引入位置信息使得方案更健壮,形式化分析证明该方案是安全的.基于MICAx系列无线传感器网络节点的能耗分析结果表明:方案能很好地适用于资源受限的WSN环境.

Reciprocal Authentication Based on a Conic Curve Combined Public Key in Wireless Sensor Networks

Comprehensive analysis was conducted on the development trends and deficiencies of a wireless sensor network(WSN) with authentication protocols,especially with regard to encryption,public key cryptography binding,and answer attack modes,to provide location information based on a scheme for reciprocal authentication of personal ID nodes.The scheme utilizes conic curve cryptography(CCC),which is more efficient and easier to use in inverse operations,order computations, and point multiplication computations th...
