Abstract: A system includes at least two buses including a first bus and a second bus, an encryption and decryption system corresponding to each bus, at least one signal processing module corresponding to each bus, and a bus converter coupled between the first bus and the second bus. According to the system provided in embodiments of the present invention, because data transmitted on a bus is encrypted data, even though an attacker obtains bus data by means of a probe attack, it is quite difficult to break a key, and an anti-attack capability of the system can be improved.

Abstract: Embodiments of the present application disclose an operation method. The method includes: obtaining, by the input/output interface, an input ciphertext; performing, by the decryption circuit, a modular exponentiation operation according to the ciphertext and a preset operation parameter; and using, by the microprocessor, an operation result obtained after the modular exponentiation operation as a plaintext obtained after decryption. The performing, by the decryption circuit, a modular exponentiation operation according to the ciphertext and a preset operation parameter is specifically: breaking, by the decryption circuit, the modular exponentiation operation into multiple iterative first operations, where the first operation is a modular square operation or a modular multiplication operation; sending, by the decryption circuit, the ciphertext and the operation parameter to the arithmetic unit; and performing, by the arithmetic unit, the first operation according to the ciphertext and the operation parameter to obtain a modular square value or a modular multiplication value

Abstract: This application relates to the field of communications technologies, and discloses a mobile payment method. The method is applied to a system on chip SOC, where the SOC includes a secure element SE integrated into the SOC, and the method includes: receiving, by the SE, a transaction request; obtaining, by the SE, a first check value from an external memory; performing a security check on the external memory according to the first check value and a second check value that is stored locally in the SOC; and if the external memory passes the security check, obtaining, by the SE, first transaction data from the external memory, and processing the transaction request based on the first transaction data. This application is applied to a mobile payment process.
