摘　　要：针对文献[14]提出的所有权转移算法存在多余计算步骤等问题,在其算法框架基础之上设计一个改进的所有权转移算法。改进算法精简了通信步骤,避免出现冗余计算;改进算法对信息加密过程中采用计算量更低的遍历异或运算进行,摒弃原算法采用Rabin加密算法,从而降低系统整体计算量;会话过程中精简了算法步骤,降低了系统整体通信量。从安全、计算量角度进行对比分析,该算法满足RFID系统所需的安全需求,且适用于计算受限的标签中,具备推广的价值。Aiming at the problem that the ownership transfer algorithm proposed by reference[14]has redundant calculation steps,this paper designs an improved ownership transfer algorithm based on its algorithm framework.The improved algorithm simplified the communication steps to avoid redundant calculation.It adopted the ergodic XOR operation with lower calculation amount in the process of information encryption,and it abandoned the Rabin encryption algorithm used in the original algorithm,so as to reduce the overall calculation amount of the system.The algorithm steps were simplified in the process of conversation,so as to reduce the overall communication amount of the system.The algorithm was compared and analyzed from the perspective of security and computation.The results show that this algorithm meets the security requirements of RFID system,and is applicable to tags with limited calculation,which has the value of promotion.
