摘要：The present invention discloses an encryption method and an encryptionapparatus. The encryption method comprises: generating an AES initial key by using anSAES encryption algorithm, and expanding the AES initial key to obtain an AES encryptionkey; and encrypting information to be encrypted by using the AES encryption keyaccording to an AES encryption algorithm to generate encrypted data. As such, the AESencryption key is encrypted by introducing the SAES algorithm, which increases thedifficulty in cracking the AES encryption key. An attacker may crack the AES by firstlycracking the AES encryption key, which increases the overall difficulty in cracking the AESencrypted data. Further, the SAES encryption algorithm and the AES encryption algorithmare implemented by means of an ASIC integrated in an encryption chip. Since the ASIC is acustomized circuit and no code or program can be intercepted, the risk that the SAES andthe AES are cracked due to interception of the program or code is prevented. Finally,data security is improved.
