摘要
探讨了移动自组网所特有的安全威胁,将Shamir秘密分割模型和权限思想相结合,提出了一个基于权限的门限信任模型,并提出了一种新的私钥分量刷新技术。分析结果表明,该模型在可信节点剩余很少时仍能完成网络中节点的认证,亦可避免攻击者获取足够的私钥分量进行非法认证。
The security threaten for MANET（mobile ad hoc network） was discussed. Combined the secret dividing model and the weight idea, a threshold trustful model based on weight was proposed. A new refurbishing method for private key weight was put forward. The analysis shows that this model can avoid attackers getting enough weight for the private key for lawlessly validating and validate the network nodes when trust nodes remain small.
