Abstract

The invention provides a key generation assembly used in a physical chip, and the key generation assembly comprises a random number generator which is used for responding to a first signal so as to generate an unpredictable coding value; a burning unit which is used for executing the operation of burning the coded value into the OTP storage unit; and an OTP storage unit is used for solidifying thecoded value to serve as a private key. According to the invention, the private key in the key generation assembly is generated by the unpredictable random number in the chip; According to the invention, the private key value does not have any relation and interaction with the outside of the chip after being burnt into the OTP module, the uniqueness and undetectability of the private key are ensured, and the private key cannot be known no matter whether the component is externally provided with a development designer or an attacker, so that the security and reliability of the private key are ensured.

Description

technical field [0001] The invention belongs to the technical field of data encryption / decryption, in particular to a key generation component used in a physical chip. Background technique [0002] Data has been proven to be one of the important assets of enterprises, and the rapid growth of data has made enterprises face unprecedented challenges. In view of the current data security requirements, the mainstream technology is encryption / decryption processing through cryptographic algorithms, and key management as the basis of encryption / decryption processing. [0003] The key refers to the paired public key and private key. The public key is the public part of the key pair. It is usually used to encrypt session keys, verify data signatures, or encrypt data streams that can be decrypted with the corresponding private key; The key is the non-public part of the key pair, which is usually used to decrypt the session key, perform data signature, decrypt the data stream encrypted...
