An encryption authorization scheme of an algorithm library

Abstract

The invention relates to an encryption authorization method of an algorithm library. The algorithm library is loaded on a client device. When the client device activates the algorithm library, whetheran authentication file is stored in the client device is detected, and if so, the decoding step is executed. If not, an authorization request is sent: the identification information of the client device is collected and then sent to the background server together with the account information of the client device and token; After verifying the account information and token, the background server calls the corresponding core parameters of the algorithm library from the background server, and then makes an authentication file combined with the device identification information, and then sends the authentication file to the client device. The client device saves the file and then performs the decoding step. The invention not only guarantees the safety of the algorithm library, but also facilitates the algorithm supplier to manage the authorization of each equipment. Even if the algorithm library of the customer is embezzled, the algorithm library can be found in time, and the illegal client end is prevented from using the algorithm library effectively.

Description

technical field [0001] The invention relates to an encryption authorization method for an algorithm library, which belongs to the field of information security. Background technique [0002] Traditional POS machines often only have the function of swiping cards. With the maturity of the Android system, there are more and more smart POS machines using the Android system on the market; at the same time, with the maturity of barcode payment technology, the functions of POS machines can no longer be limited It needs to adapt to barcode payment, so it needs to add the function of QR code scanning to receive and pay; most POS machine manufacturers do not have 2D decoding algorithms that meet the decoding capabilities of UnionPay standards, so they need to use algorithm suppliers Algorithm libraries for decoding are provided for licensed production. For the protection of the algorithm library, the algorithm library cannot be directly provided to the POS machine manufacturer, but t...

Problems solved by technology

If the algorithm library is directly provided without encryption processing, the algorithm supplier will suffer huge losses, and the simple encryption method is less difficult to crack, and some manufacturers may be able to crack it through certain means, so that the algorithm can be used at no cost library; if a manufacturer is charged for authorization by year or time, it is not easy to formulate a reasonable charging price without knowing the manufacturer's annual output, and manufacturers tend to falsely report the number of authorizations, making the algorithm library Supplier suffers financial loss
