SMC And The Research And Application Of It In The Mechanical Engineering Field

With the development of Internet, it has been becoming more and more popular for its users to compute cooperatively. Namely, the Internet users cooperate to complete some computing mission, which maybe occur in the conditions of confidence one another fully, partly or even adversely. It is very easy for the first like our doing everyday. But it will be a troublesome issue for the others that not cooperate. Due to privacy and data security, the partner wishes to carry through beneath his own data unknown. For resolving this problem we develop the concept of Secure Multi-party Computation. SMC extend the traditional distributed computation and data security. And as a new computation method, it is very important for data security, especially under the circumstance of Internet.SMC is an important branch of modern cryptography and studying field of data security. Secure Multi-party Computation and Distributed Cryptography is the basis of modern cryptography. SMC means generating a shared output after the partners' inputting respectively and secretly, when make sure the accuracy even under attack and the security that not release any personal inputs except the common output.SMC's core is:the flock can use a particular multivariable function to get an all-member-known output, and all about the individual's input is unknown.SMC also can be described as:n participants, who each participant has a secret input, want to get a shared output by function, during and after the computation all of the input is private for all members.The paper discusses several field of SMC as below. The paper designs several basic secure bi-or-multi-party computation protocols and proves its accuracy and security. The paper designs the secure two-party computation protocol in linear substitute, introduces the concepts of it related and puts forward several protocols under the circumstance of half-honest model and n demission vector space.The paper introduces the concept, function and categorization of data processing, the content and essence of data processing research and the application of data processing and the design of protocol for privacy-preserving data mining, and analyzes the validity and complexity of the protocols.The paper introduces the basic knowledge of electronic election, the development of electronic election, the basic qualification of electronic election scenario and several electronic election scenario analysis and design, and develops an valid electronic election scenario.The paper introduce the development of mechanical engineering, service sector, the subject of mechanical engineering, mechanical and electronic integration and the basic know-how of mechanical engineering. And put forward the application of SMC for Agile Manufacturing technology and mechanical product marketing in the line of mechanical engineering.
