摘要： Various techniques related to authenticating and verifying the integrity of data received by a computer system from an external source (such as a sensor) are disclosed. Hardware circuits are disclosed that, along with the computer processor, allow for error-checking and authentication of data received by the computer system. For instance, the hardware circuits may generate a separate authentication code that can be compared to the authentication code in the data itself to determine whether or not the message is authentic and whether or not there is an error in the data. The disclosed techniques reduce the processing requirements of a computer system and can be implemented using simple hardware circuit designs.
