Embodiment Construction

[0032] now refer to figure 1 , the computer device 10 is arranged to execute a software application 20 . The computer device may be, for example, a conventional personal computer, tablet computer, mobile phone or other mobile device, or the like. The invention is typically implemented for a large user base of such computing devices. The software application 20 may typically be stored on a hard drive, a solid state disk, or in some other form of persistent storage for loading into random access memory of the computer device 10 in preparation for execution.

[0033]A known attacker attempted to attack a software application. This may involve, for example, reverse engineering the corresponding executable and / or modifying the executable to access features / functions and / or information that might not normally be available to an attacker. For example, the attacker may not have paid for access to a certain function of the application (for example, if the attacker has not obtained t...

Abstract

There is described a method of executing a software application on a device by including a secured cored within the software application, and providing a system verification function within the secured core. The system verification function is used to scan for exploits against the application, for example local exploits seeking to recover cryptographic keys which may be found within the application when executing, with reference to exploit signature data which may be provided by an external server.

Description

technical field [0001] The present invention relates to a method and apparatus for executing a software application on an apparatus capable of detecting and defeating an exploit for a software application and an apparatus and system arranged to execute the method. Background technique [0002] When attempting to protect software applications on computing devices from tampering, security may only really amount to the weakest attack path. Software applications can often be attacked using many different techniques and paths, some of which may not have been contemplated when the software was originally designed and written. Attackers will tend to take the easiest path of attack and will often invent new paths instead of attacking well-protected paths. [0003] Often, a certain kernel of a software application is well protected to the extent that an attacker is unwilling or unable to attack it, or an attack against it will take long enough. However, outside of this core, there ...
