Rational cryptographic protocols (Rational Cryptographic Protocol) is a relatively new field of study , belongs to a branch of algorithmic game theory . Its main purpose is based on the language and tools of game theory provide a new explanation for secure multiparty computation and composition of multiparty computation problem analysis with multiple target different participants . Rational cryptographic protocols rapid development in the international community , not only the integration of economics and computer science , but also in the field of computer science , it combines the theory of algorithms , cryptography , complex computational theory and artificial intelligence disciplines . Rational cryptographic protocols for preliminary research , in-depth study of the theoretical mathematical model and analysis strategy selection and earnings of participants . Rational cryptographic protocols to solve practical problems by traditional secure multi-party summation protocol to improve the process of learning and research master security multi- product agreement on this basis , some improvements to make the implementation process more in line with the real world objective laws . This article also rational cryptographic protocols applied to practical problems. Justice Diffie-Hellman protocol based on the application of rational cryptographic protocols to improve it , to construct a new rational key escrow scheme . At the same time , this article describes a of rational cryptographic protocol digital fingerprint .
