Secret methods for electronic components

The main purpose of keeping electronic components confidential is to protect the design, one is the design with a program, and the other is the protection of the electronic circuit without a program.

Using hardware encryption method

Hardware encryption can be managed using standard network management protocols, such as SNMP, CMIP, etc., or it can also be managed using a unified network management protocol.

Hardware encryption implements cryptographic operations through a dedicated encryption chip or an independent processing chip. When the encryption chip, proprietary electronic key, and hard disk are mapped together one by one, the encryption chip will match the encryption chip information, proprietary key information, and hard disk information and perform encryption operations, and write them into the primary partition table of the hard disk at the same time. At this time, the encryption chip, proprietary electronic key, and hard disk are bound together, and it will be impossible to use without any one of them. If the encrypted hard disk is separated from the corresponding encryption chip and electronic key, the partition will not be recognized on the computer, and no data will be obtained.

It is difficult to restore data if the password is lost

Hardware encryption can be achieved by mounting an encryption chip (encryption IC), such as AT88SA102S with a 256-bit key. In this way, when the program is In the case of copying, the program cannot run without the encryption chip AT88SA102S.

Grinding components

Use special tools to polish off the silk screen numbers on the components.

Component canning

The components containing sensitive chips are packaged and cannot be opened, as opening them will damage the components.
