摘要： A control flow enforcement solution for ensuring that a program or portion thereof behaves as expected during execution upon a processor. A reference control flow is pre-determined for the program using, for example, a control flow graph (CFG). The CFG is then analysed to provide a set of rules which describe how the program should behave under normal execution. As the program executes it is monitored and the rules are evaluated to enable detection of any unexpected control flow. An embodiment of this disclosure is configured to respond upon detection that a rule has been violated. The response can take the form of any appropriate intervention such as a processor interrupt, memory fault, processor reset or generation of an alert. In this way, an embodiment of this disclosure may provide a particularly effective mechanism for detecting and defending against malicious activities such as return oriented programming attacks. The invention can be utilised to effect with any program but may be particularly suited for use with programs executing upon embedded processors.

摘要： In order to reduce latency of elliptical curve digital signature generation a portion of the digital signature is pre-calculated before receipt of the message hash using an unmodified ECDSA computing engine. After the message hash is received, the digital signature is completed without using the ECDSA computing engine. Applications include generating digital signatures for the safety messages in Intelligent Transport Systems.

摘要： A public key architecture (160) includes a dual certificate hierarchy which facilitates two independent authentication functions. One of the authentication functions authenticates an authentication device (164) to a verification device (166). The other authentication function authenticates a configuration device (162) to the authentication device (164). In some embodiments, the authentication process uses a lightweight certificate formed in conjunction with a lightweight signature scheme (370).

摘要： A method of binding a software to a device is disclosed. Accordingly, during a setup of the software in the device, a unique identifier is derived from contents stored in the device and the derived unique identifier is encrypted. The derived unique identifier is then stored in a configuration of the software. During a next invocation of the software in the device, a new unique identifier is derived from the contents stored in the device. The newly derived unique identifier is then matched with the stored unique identifier. The execution of the software is terminated if the matching fails.
