Abstract
The present disclosure discloses an encryption method and an encryption apparatus. The encryption method comprises: generating an AES initial key by using an SAES encryption algorithm, and expanding the AES initial key to obtain an AES encryption key; and encrypting information to be encrypted by using the AES encryption key according to an AES encryption algorithm to generate encrypted data. As such, the AES encryption key is encrypted by introducing the SAES algorithm, which increases the difficulty in cracking the AES encryption key. An attacker may crack the AES by firstly cracking the AES encryption key, which increases the overall difficulty in cracking the AES encrypted data. Further, the SAES encryption algorithm and the AES encryption algorithm are implemented by means of an ASIC integrated in an encryption chip.
