恶意模型下汉明距离的保密计算
Confidential computation of Hamming distance under malicious model
摘要
Abstract
Aiming at the problem of calculating the Hamming distance of different strings under the condition of privacy of confidential data,this paper first defines the 0-1 encoding rule,and then designs a secure protocol to calculate the Ham-ming distance under the semi-honest model based on the elliptic curve encryption protocol.Aiming at the possible malicious behaviors,the protocol of securely computing the Hamming distance under the malicious model is designed by using the methods of cut-choose and zero knowledge proof.The security of the protocol is proved by the real/ideal model paradigm.Efficiency analysis and simulation experiments are conducted on the two protocols and existing protocols.Through compari-son,the efficiency of both protocols in the semi-honest model and malicious model is improved.关键词
