This disclosure provides a data processing method, system, electronic device, and medium for model inference scenarios. The data processing method includes: writing target data to be transmitted in the model inference scenario into at least one write area in a preset buffer using a data stream; obtaining different sensitive data and sensitive data pointer information in the write area based on sensitive data identifier information in the data stream, and generating structure information to obtain an initial sensitive data linked list; encrypting different sensitive data in the write area using a first preset data processing algorithm and the initial sensitive data linked list to generate a target sensitive data linked list, and transmitting it to the device in the model inference scenario. This disclosure can ensure the security and integrity of sensitive data transmission from the host to the device, effectively avoid the leakage of sensitive information, and ensure the security and reliability of the entire data transmission process.

The application provides a kind of monitoring protection circuit of control signal, for protecting safety chip, the circuit includes: signal monitoring unit and alarm processing unit, wherein: the signal monitoring unit is used to detect the state of SEN control signal containing sensitive logic in real time, when safety chip is attacked, if the level of the SEN control signal is detected to occur abnormal mutation, then high level alarm signal is generated;The alarm processing unit is used to control the safety chip to respond and process according to the high level alarm signal, to strengthen the security mechanism of the safety chip.The application generates an alarm after the key signal is attacked and changed, and the related circuit responds to the alarm signal, takes over the system control signal of the chip, ensures that sensitive data will not be obtained by abnormal attack, so as to ensure the safety of the chip and avoid the problem that the related security measures are invalid due to the attack on the key signal.
