Design and Comparative Analysis of Cryptography Schemes Based on Oblivious Transfer
With the development in digital age,demand on data security and privacy protection is in-creasing.As an important security technology,cryptography scheme based on oblivious transfer plays a significant role in protecting data security and user privacy.In this paper,cryptography schemes based on oblivious transfer are designed and compared.First,application requirements are analyzed in fields of digital product transaction,location service privacy protection and blockchain data confidential que-ry,etc.With sufficient considerations of feasibility,security and performance overhead,oblivious transfer schemes that satisfy corresponding security and privacy protection requirements are designed.Then,three cryptography schemes based on oblivious transfer are compared in terms of security,func-tion,performance and practicability,which may provide reference and guide for practical applications in various fields.Finally,merit and demerit of each scheme is summarized,and future research direc-tion for cryptography scheme based on oblivious transfer is prospected.
