Add arithmetic module into the reader to encrypt the seed data and form symbol information for storing into storage module to enhance the security.
Description
Technical field
The present invention relates to the application of IC cards field, particularly a kind of card reader of energy customizing flag information.
Background technology
Along with popularizing of smart card, the electronic product of its application has also obtained extensive attention.Wherein card reader is modal a kind of.Card reader is applicable to that electronic fare payment system, authentication etc. need be to the fields of smart card information reading writing working, USB interface by hardware inside connects main frame, connect smart card by the interface that meets 7816 agreements, realizing the communication between main frame and the smart card, is the desirable electronic product of authentication, ecommerce, Home Banking, information security, visit and identity control and other Secure Application.
The existing customer propose to buy can customizing flag information card reader, but on the market card reader can not satisfy this requirement at present.Customizing flag information and is to be write direct in the storer of electronic equipment by production firm or client normally in other electronic equipment, and Ding Zhi flag information security is not high like this.
The production technology of storer can be divided into two classes: volatibility and non-volatile.The data that volatile memory is stored after outage can be lost, and nonvolatile memory has the characteristic that can not lose the data of being preserved after the power down, as FLASH, EEPROM, FRAM etc.
When data are encrypted, adopt two class algorithms usually: one-way algorithm and two-way algorithm.
One-way algorithm also claims HASH (Hash) algorithm, is meant under the situation of known operations result and algorithm also the algorithm that can not backwards calculation goes out raw information.One-way algorithm commonly used has MD5, SHA-1, RIPEMD series etc.Hash function has a kind of like this function: it produces the output of regular length to the input information (being commonly called as seed) of different length.The output of this regular length is called former input information " hash " or " Message digest (eap-message digest) ".The hash function H of a safety must have following attribute:
1) H can be applied on the data not of uniform size;
2) H can generate fixed-size output;
3) for any given input information x, the calculating of H (x) is simple relatively, fast;
4) for any given code h, the x that find to satisfy H (x)=h is infeasible on calculating;
5) for any given input information x, find to satisfy H (x)=H (y) and with the unequal y of x on calculating, be infeasible.
Two-way algorithm is meant the algorithm that can encrypt, decipher, promptly can become ciphertext to plain text encryption, also can derive algorithm expressly from ciphertext.The two-way algorithm that has adopts the unsymmetrical key system, and this is meant that encryption key and decruption key are the cryptographic algorithm of two different keys.Exist relation of interdependence between these two keys: promptly the information of utilizing wherein any one secret key encryption to obtain can only be decrypted with another key.
