摘要: 无源器件的能量和计算资源有限。针对这种器件的安全认证需求,提出了一种新的哈希方法M-hash。该方法基于低复杂性的并行输入LFSR,即多输入特征分析寄存器(MISR),采用并行压缩方法,具有硬件复杂性低、速度快等特点。理论分析和具体硬件实现表明,M-hash在硬件复杂性、压缩速度和安全性等方面均优于另外一种基于LFSR的Toeplitz哈希方法。

Abstract: Passive devices have limit power and computing resource. Aiming at the security authentication of this kind of devices, a new hash function-M-hash is proposed. Based on low hardware complexity parallel input Linear Feedback Shift Register(LFSR), Multiple Input Signature Register(MISR), the M-hash takes parallel compaction method and with property of low hardware complexity and high speed. Theory analysis and hardware implementation show that M-hash is better than Toeplitz hash functions that are also based on LFSR in aspects of hardware complexity, compaction speed and security.
