Abstract
Systems, methods, circuits and computer-readable mediums for message authentication with secure code verification are provided. In one aspect, a system includes a client device storing a code and a security device coupled to the client device. The security device is configured to receive a property of the code generated by the client device, verify correctness of the property of the code based on information associated with the code to determine that the code is an authorized code, the information being stored within the security device. In response to determining that the code is the authorized code, the security device enables to access data stored within the security device and generate a property of a message based on the data.
