A method for validation of virtual function pointers includes compiling a source code file with one or more classes whereby each of the classes has a virtual table, and the compiling includes associating a security check function with the virtual function invocation site such that the associated security check function is executed prior to an invocation of the virtual function, generating a class hierarchy hash table (CHHT), whereby when the compiled source code file is executed, the security check function is used to determine whether an invoked virtual function pointer of a virtual function associated with the security check function is valid by looking up an indicator in the CHHT according to a hash result of the virtual function pointer and an address of a virtual table containing the virtual function pointer.

Device and method for validation of virtual function pointers

A vehicle-mounted device upgrade method and a related device. The method may be applied to a vehicle-mounted system, a vehicle-mounted control device and one or more to-be-upgraded vehicle-mounted devices, and the method may include: obtaining, by the vehicle-mounted control device, a vehicle-mounted upgrade package, where the vehicle-mounted upgrade package includes a plurality of upgrade files, and each upgrade file is used to upgrade at least one to-be-upgraded vehicle-mounted device; performing, by the vehicle-mounted control device, security verification on the plurality of upgrade files; and sending, by the vehicle-mounted control device, a target upgrade file to a target to-be-upgraded vehicle-mounted device that is to be upgraded by using the target upgrade file, where the target upgrade file is an upgrade file on which security verification succeeds in the plurality of upgrade files. According to this application, the vehicle-mounted device can be securely and efficiently upgraded.

A system and method generate private keys for devices participating in a self-certified identity based encryption scheme. A private key is used by the devices to establish a common session key for encoding digital communications between devices.

System and method for computing private keys for self certified identity based signature schemes

A method for authenticating a connection between a user device and a vehicle includes sending, by the vehicle, a first wireless signal through a connection channel, receiving, by the vehicle, a second wireless signal through the connection channel, and acquiring, by the vehicle, a second signal strength sequence from second N continuous signal strength characteristics (PF) of the second wireless signal, receiving, by the user device from the vehicle, the first wireless signal, acquiring a first signal strength sequence from first N continuous signal strength characteristics (PF) of the first wireless signal, and communicating, by the user device, the first signal strength sequence to the vehicle.

System and method for authenticating a connection between a user device and a vehicle using physical layer features

This document describes a system and method for generating two types of session keys for encoding digital communications between two devices. In particular, the first type of session key possesses escrow properties whereby a trusted third party will be able to generate the first type of session key to decode the digital communications between the two devices while the second type of session key does not possess escrow properties.

System and method for computing an escrow session key and a private session key for encoding digital communications between two devices

This document discloses a system and method for verifying system integrity of an electronic device. The electronic device includes a verifier device provided within a secure environment of the electronic device and a scanner device provided within a normal environment of the electronic device whereby the secure environment comprises hardware that is isolated from the hardware in the normal environment, i.e. these two environments are hardware isolated.
