摘要
An efficient obfuscation of program control flow, comprising obscuring a control execution flow through a plurality of code blocks of a computer program. It involves obtaining a secret key, initializing a state variable based on the secret key, generating a switching value by processing the state variable through an encoding function, and selecting a code block from among a set of code blocks using the switching value. It further involves executing the block code, which comprises updating the state variable based on a present value of the state variable, and repeating the steps of generating a switching value, selecting a code block, and executing the code block to control execution flow through the set of code blocks.
