摘要：

针对计算资源受限设备易遭受擦除攻击的问题,在HB协议的基础上提出2种改进方案,使基于带噪声的校验学习的加密认证协议能够抵抗擦除攻击。第1个方案为共享密钥增添一位校验位,从而检测并避免擦除攻击。第2个方案将密钥编码成汉明码,即使在擦除攻击发生的情况下也能恢复密钥。实验结果表明,2个方案都能在保证原协议安全性的基础上,增加抗擦除攻击的属性。

Abstract:

In this paper,two improved schemes based on HB protocol are proposed for erasuring attacks on computing resource-limited devices,to make Learning Parity with Noise(LPN)-based cryptographic authentication protocol can resist erasure attacks.The first scheme adds a parity bit to the secret key to detect the erasure attack and then resists it.The second scheme uses Hamming code to encode the secret key.It keeps the original key even the erasure attack works.Experimental results show that both of the two schemes can increase the anti-erasure attack property on the basis of maintaining the security of the original protocol.

Key words: shared-key authentication protocol, erasure attack, Learning Parity with Noise(LPN) problem, HB/HB+protocol, Hamming code
