The Design And Implement Of Secure Portable Terminal Based On ECC Algorithm

Along with the development of society and economy, the finance serves ceaseless system expansion, finance service needs the diversification being made complicated gradually. The handled time of some finances business is very time-consuming, such as open deposit cards, sign the contract for electronic channel, CTS serves can only be handled at Bank counter, the customer who covers point as with a net handling business is crowded, the customer in counter sign a contract, without queue time, need cost about 4-6 minutes, consume time to bank customer growing comparatively, Increasing the business pressure for the net-pots in the bank system. How to change this phenomenon for consumers lining up to bank and other banking institutions, for masses and enterprise consumer providing the high-effect finance serves immediately becomes the focal point. Finance of our country serves system at present, the bank, insurance, bond wait for the industry business to handle systematic major part requiring that the customer handles various business in person for instance, the finance business objective being able to entrust charge affaires fixes a part have also increased addition of the staff member going there and back handling time and energy,this situation can not satisfy customer's moreover under many condition, also is difficult to give sufficient guarantee immediately in the field of information safety. Change a bank waiting for the banking institution service way, from waiting for a customer to drop in to handle business that the customer handles various business on his own initiative, but hoist marketplace competition expansion market share further thereby, become real problem that the bank and banking institution show solicitude gradually.Aimed at problems above,the main body of this paper have suggested that one kind of the safety making use of algorithmic technology of ECC principle and safety characteristic property to carry out the new model encrypting protection on network equipment communication module moves a terminal, in the field of data safety transmission this system has adopt the PKI secret key frame to be hit by the standard interface of CSP (Cryptographic Service Provider) coming to carry out the figure signature to ensure the information nothing to tamper with nature and to there be no deny, has designed and the systematic overall frame on the basis here. The merit owing a terminal the system having synthesized symmetrical password system and the public key password, has made use of the security realizing a terminal owing to algorithmic safe ECC chip, system has adopt ISO8583 which adopted broadly by financial bank system to wrap up the business information calibration agreement being two really by agreement, and the basis being in the ISO8583 agreement has mounted addition in the respect of ensuring that the displacement terminal is in the business software module under safe reliable premise, have individuation added value service business which can satisfied high-effect finance a lot of business system need such as not only insurance, bank, But apply to handling business in financial industry.
