MSN 中用户属性隐私安全的选择性匹配协议
Privacy-preserving selective profile matching protocols for MSN
摘要
Abstract
To handle the selective profile matching problem ,a similarity metric function was designed at first ,and the privacy‐preserving protocols were proposed on the basis of Paillier cryptosystem . Then ,both efficiency preferred selective matching (EPSM ) and privacy preferred selective matching (PPSM) protocols were designed ,with consideration of different privacy requirements and time lim‐its .EPSM protocol is efficient in finding the matching users but less secure than the PPSM protocol , w hile PPSM protocol needs participants to confuse their responses resulting in higher secure level but less efficiency than the EPSM .In addition ,security and efficiency analyses were conducted .The re‐sults suggest that the proposed protocols ,which make sense in different privacy requirements and time limits ,are privacy‐preserving and correct .关键词
