Abstract

A method of securing a software routine implemented in a software instance executing in an execution environment, the method comprising: initializing a code block of the software instance with a reference to the software routine by storing the reference such that the stored reference is inaccessible to code outside of the code block; and returning a reference to the code block, the reference to the code block used by the software instance outside of the code block to invoke the software routine; wherein the code block is configured to: (a) invoke the software routine using the stored reference, and, (b) after a predetermined number of invocations of the software routine by the code block, modify the stored reference so as to prevent further invocation of the software routine by the code block.
