Luo Wen-jun · Jisuanji yingyong yanjiu · 2009
Private-preserving dot product protocol is an important protocol of many secure multi-party computation problems,and is generally used in many privacy-preserving data mining protocols,providing important security guarantee for these protocols. At present,some existing private-preserving dot product protocols are secure at most in the semi-honest model. This paper constructed a privacy-preserving two-party shared-dot product protocol based on some basic cryptographic techniques which was secure in malicious model,this protocol had more security than those of previous protocols. The potential areas of application of this protocol are numerous,for example,computation of Euclidean distance,privacy-preserving computational geometry,privacy-preserving cooperative statistical analysis and so on.
