三个保密计算服务协议

Three specific secure computation service protocols

引入保密计算服务的概念,研究了三个具体的保密计算服务问题,提出了基于随机变换的保密计算解决方案.对广泛接受的模拟范例进行扩展,用扩展的模拟范例证明了提出的三个保密计算服务协议是安全的.利用保密计算服务协议,接受计算服务的一方可以用很少的计算资源解决复杂的计算问题,同时又可以保证问题的机密.

The concept of secure computation service is introduced;three specific secure computation service problems and discussed are their solutions are proposed based on random transformation.A well-accepted simulation paradigm is extended to secure computation service,and the extended simulation paradigm shows that the proposed protocols are private.Using these protocols,the service receiver can solve very complicated computation problems with very limited computing power without disclosing the privacy of the computation problems.
