Description

A kind of based on many application processes of the CPU card for consuming key more

Technical field

The invention belongs to CPU card applied technical field, more particularly to insurance, traffic police, government industry, finance, traffic, business The fields such as industry, aviation a kind of based on many application processes of the CPU card for consuming key more.

Background technology

CPU card is applied to the multiple fields such as finance, insurance, traffic police, government industry, with user's space greatly, reading speed The features such as hurry up, support one card for multiple uses；With the continuous expansion of CPU card application, CPU card technology is constantly ripe, CPU card on market Type and quantity are all being on the increase, a mass transit card one, and the CPU card in the whole nation alreadys exceed 800,000,000.

As financial IC card snaps into the excessive of CPU card from magnetic stripe, the storage of CPU card further will increase.CPU card quantity Increase, increasing for application will cause the increasing number that holds of each user, be user for the use of CPU card brings not Just, therefore multi-application card or all-purpose card become the content that CPU card project will be related to, for example, the band finance of portion of people society distribution The social security card of function, the residents ' health of Ministry of Public Health's distribution are stuck on Specification Design and all consider the problem that applies a card more.

Existing CPU card supports that the mode of many applications is all that each application adopts one using multiple application logic isolations There is an independent security domain, this kind of mode to have for DDF DDF or automatic position search engine ADF, each application Following shortcoming：(1) when making the multi-application card that issues in this way, as each application adopts independent security domain, with one The independent key of set, is therefore required for redeploying new division operation POS when deployment is implemented, replaces original system POS, so as to support multiple applications on new POS, the CPU card of corresponding existed system is often replaced using recovery or in POS Upper individually exploitation has CPU card, there is a problem of that compatible existed system is difficult, relatively costly；(2) when multiple applications have offline Stored value card, electronic cash or during electronic bankbook, user is the offline wallet balances using multiple applications, generally require with To each wallet will have the amount of money, exist in-convenience in use, cause user's fund waste, be unfavorable for user using ask Topic；(3), in many application consumption flow processs of existing CPU card, the consumer need of multiple applications selects multiple ADF, and before consuming It is required to judge whether the wallet balances in various applications disclosure satisfy that spending amount, the wallet amount of money in multiple applications can not General；And when needing to improve the situation that this remaining sum can not be general, need POS to carry out extra circle and carry, enclose to deposit etc. and operate, step More, to implement to replicate, the system of current operation is not applied substantially.

Therefore, CPU card applied technical field is badly in need of one kind in a CPU card application while loading multiple consumption keys, And separate records consumption when each consumption key is consumed is counted so that an application can disappear in multiple systems simultaneously Take, realize many application purposes, simple to operate based on many application processes of the CPU card for consuming key more.

Content of the invention

The invention provides a kind of based on many application processes of the CPU card for consuming key, technical scheme is as follows more：

A kind of based on many application processes of the CPU card for consuming key more, it is characterised in that comprise the steps：

Step one, operation program is solidificated in signal processing module in binary form, then will be produced by chaotic maps Raw pseudo-random sequence, fascination key and private key are all solidificated in public key module in binary form；

Step 2, repeat step more than times so as to produce multiple pseudo-random sequences, fascination key and private key, and difference It is solidificated in public key module with binary form；

Step 3, when CPU card is in consumption status, signal processing module order consumption module is initialized；

Step 4, after the completion of initial work, signal processing module command control unit reads the user identity in CPU card Prove and card number；

Step 5, signal processing module proves the user identity for reading and card number passes to public key module, public key mould Block proves the public key cryptography for calculating CPU card with card number according to user identity；

Step 6, when CPU card is consumed on different machines, signal processing module can read different users Proof of identification, card number, consumption time, terminal number and MAC Address, are operated according to step 5, and public key module is according to user's body Part proves and card number can obtain multiple public key cryptographies, often produces a public key cryptography, and CPU card can record one-time-consumption automatically, disappear Take number of times to be constantly overlapped, and pass to data memory module and stored；

Step 7, when the consumer record to CPU card carries out reconciliation, it is only necessary to which signal processing module called data stores mould Corresponding MAC Address below multiple public key cryptographies in block, you can whether effectively to judge consumer record, and can check Obtain the concrete consumption information corresponding to specific public key cryptography.

A kind of based on many application processes of the CPU card for consuming key as above more, wherein, in step 5 public key module according to Prove according to user identity and card number calculates the public key cryptography of CPU card and comprises the following steps that：

First, public key is calculated and realizes that public key is with times point addition on elliptic curve：

Wherein, IPK represents public key,The corresponding value of element in public key matrix is represented, according to the difference of ID, configuration Different coefficients, produces different users, and then produces different chaotic maps, according to public key, further draw Sc_iPseudo- with Machine sequence.

The invention has the beneficial effects as follows：In the same application of same CPU card, increase multiple consumption keys, reach To the purpose of CPU card many applications in multiple parallel systems, on the basis of security, availability is not reduced, use is solved Card multiple offline wallets in family need the problem that independently supplements with money；When also solving system deployment upgrading, the compatibility to original system Cost is less, and can also enable new legacy system in the period of certain while operation, solves system upgrade and compatibility is old The difficult problem of card.
