“Information security is essential to protecting personal privacy, corporate trade secrets, state secrets, etc. It prevents information from being acquired, used or leaked by unauthorized individuals, organizations or entities, and ensures the confidentiality, integrity and availability of information. In addition, good information security measures can enhance the public’s trust in enterprises and organizations, and help maintain the reputation and market competitiveness of enterprises.”
1.Based on the encrypted file, the key is encrypted again.
2.Decrypt the key encrypted using an asymmetric algorithm and ensure that the key is not leaked.
3.Use the key to decrypt the burned file and ensure that the decrypted file is not leaked.
4.Flash the program on the ECU and activate the hardware security module.
5.Flash the decrypted bootloader and application.
6.Configure the ECU’s bootloader protection and disable the JTAG programming port.
A1：We provide encryption protection for the entire process from R&D, transmission to production, basically eliminating the possibility of human access to user file information.
A4：No impact. We have temporary file protection after decryption.
A2：We provide double encryption, using both symmetric and asymmetric encryption for dual protection, to ensure that user files and keys are stored throughout the entire process.
A5：Yes. We have license management and secondary publishing solutions.
A3：OPTEEQ programmer has a powerful algorithm and supports national and European encryption level requirements.
The three elements of security are the basic components of security, namely confidentiality, integrity and availability.
Confidentiality：It is required to protect data content from being leaked, and encryption is a common means to achieve confidentiality requirements.
Integrity：The data content that needs to be protected is complete and has not been altered.
Availability：The resources required to be protected are “available on demand”.
The three elements of information security have a wide range of uses. When designing security plans, doing security testing, and so on, the three elements of information security will be considered as one of the key points to comprehensively think about the problems we face.
OPTEEQ full-process management dual encryption programming solution advantages: in line with the dual standards of national and European cryptographic algorithm specifications. Compared with other products on the market, the OPTEEQ programmer has a more powerful algorithm and supports secondary encryption and decryption of files. Whether for software development or project management, the process is more secure and confidential, and it can be said that the possibility of human contact with file information is eliminated.
