Abstract

A method comprising: providing a protected item of software to a device, wherein the protected item of software is in a scripted language or an interpreted language or source code, wherein the protected item of software, when executed by the device, is arranged to perform a security-related operation for the device, wherein the security-related operation is implemented, at least in part, by at least one protected portion of code in the protected item of software, wherein the at least one protected portion of code is arranged so that (a) the at least one protected portion of code has resistance against a white-box attack and / or (b) the at least one protected portion of code may only be executed on one or more predetermined devices.

Description

technical field [0001] The invention relates to methods of providing and executing protected software items, devices and computer programs for implementing such methods and the protected software items themselves. Background technique [0002] Web computing is entering the exciting stage of the Open Web platform, and at the same time a set of open standards (such as HTML5, SVG, CSS, JavaScript, etc.) computer, mobile phone, etc.) can now work within a browser executing on any such device. Such a standard enables web applications to have all the capabilities of HTML5, such as easily inserted video and easily inserted conferencing. Similarly, such standards provide APIs for allowing web applications to access hardware and other capabilities on the device (such as local storage, GPU, accelerometer, camera, etc.). Whether the platform is a managed device with open or closed subsystems or an unmanaged device, a web application can work on any platform with a browser installed. ...
