Introduction to super dongle scheme

 

In recent years , Computer and Internet applications have been popularized and developed in China , Has penetrated into every corner of society , The government , economic , military , social , Culture and people's life are increasingly dependent on computers and networks , E-government , Paperless office 、MIS、ERP、OA And other systems are also widely used in enterprises and institutions . In the highly competitive electronic and information technology products industry , Products that many companies have worked hard to develop , It was cracked by competitors soon after it was put on the market , The time and cost of product cracking are getting lower and lower , In many industries, there are more imitations than products with their own property rights , Seriously damaged the rights and interests of product developers . At present, the most effective way to protect software and hardware products is to bind encryption chips , It can effectively prevent unauthorized access or copying of on-chip programs , It can also prevent unauthorized use of abnormal means to copy PCB, The of the product PCB Copy completely .

Chapter two Current situation of encryption chip Common types of encryption chips The principle of encryption chip is usually divided into the following ： 1） Put data inside the chip , By comparing whether the data are the same shortcoming ： Easily simulated 2） The board and the encryption chip place the key at the same time （ It can be the same , Or the same after special data operation ）, Encrypt random numbers at the same time （ It will not be reused ）, Determine whether it is a legal chip according to the result advantage ： Will not be simulated shortcoming ： If the board program is broken , The encryption chip will fail 3） Some programs of the board are transplanted into the encryption chip , Call the encryption chip function when necessary advantage ： Will not be simulated ; The board program is broken and the encryption chip is not broken , Will not affect program security shortcoming ： The high cost , User workload increases , Users need to develop security chip programs , In mass production, it is necessary to build a download program environment . There are still problems Through the encryption chip , Although it can reduce... To some extent PCB The risk of being copied , But the performance is low 、 Slow speed 、 Small storage space is a big problem , Can't protect AI Algorithm and other core modules . It is impossible to put all the business logic codes into the encryption chip to run .

The third chapter CBS Encryption chip enhancement module

1．CBS Overview of encryption chip enhancement module Shenxinda CBS Encryption chip enhancement module uses encryption chip ID、 Keys and algorithms , With the help of business system CPU Computing power of , Through container technology , Amplify the processing capacity of the encryption chip , Let all the logical code of business programs and their algorithms run in a protected secure container , Implement the security of the algorithm, its code and executable module , Not only the anti copy board , It can also prevent decompilation and cracking , It is also resistant to tampering and hacker attacks . CBS Security operation diagram of encryption chip enhancement module inner container CBS The encryption chip enhancement module amplifies the processing capacity of the encryption chip , The core functions are ： Encryption container 、 Trusted system 、 Scene white list 、 Data protection and key management of the original encryption chip .

2．CBS Main functions of encryption chip enhancement module CBS-S Encryption chip enhancement module through container technology , Use the key of the encryption chip product to generate a unique password in the system 、 Encrypted container , Let the business system run in the container , The data is stored in a container , The container is isolated from the outside , Internally trusted , Data encryption , Ensure system security , Prevent being copied and reverse analyzed .

1) Encryption container When the system starts, the key of the encryption chip is used , Encryption generation container , And let the business program run in the container , Business data is stored in containers , The container is isolated from the outside , The program files and data files in the container are not accessible from the outside . Cannot touch executable entities , Naturally, there is no reverse analysis , The container key comes from the encryption chip , Can't copy and copy board .

2) Trusted system The container is signed at the kernel level CA Calibration Technology , Sign and authenticate the system application in the container , Implement unsigned processes or processes with inconsistent signatures （ Forgery process ） Unable to run , Eliminate viruses , The operation of the Trojan horse , Make sure OS Layer security .

3) Scene white list The container is set through the white list , Form a program 、 Whitelist scenarios associated with files , All operations outside the scene are prohibited , Even system administrator privileges , The same strict restrictions .

4) File protection Design according to the principle of minimizing permissions , Read and write the data in the container 、 modify 、 Storage is strictly encrypted and authenticated , Only the specified business application is allowed to read / Write the specified file , Ensure file security .

5) Efficient encryption algorithm High efficiency encryption algorithm based on encryption chip is provided in the container , The operation of encryption algorithm is completely with the help of the system master CPU Conduct , Efficient , instant .

3． Use CBS Benefits of encryption chip enhancement module CBS-S The container generation of the encryption chip enhancement module depends on the key generation of the encryption chip , With non replicable characteristics , It has the following advantages ：

1) Encryption container uniqueness The container is generated by the encryption chip key , Have uniqueness , Do not copy .

2) All business processes run in an encrypted container The container is an external isolation , Secure and confidential computing environment , Business program all business logic code can run in the container .

3) There is no need to modify the business logic code After the business program development is completed , No code changes required , No need to transplant , No need for additional development , Just put it directly into the container .

4) Speed and efficiency Because the program in the container is with the help of the main CPU The ability to process , So the speed is very efficient .

5) Overall anti reverse engineering Because the business logic and algorithm program are in the container , The container is isolated from the outside , There is no external access to business program entity files and business data , Therefore, it is impossible to reverse analyze .
