Abstract
A method and an apparatus for receiving a first source code having a code block to update the first source code with multiple copies of the code block to protect against correlation attacks are described. The code block can perform one or more operations for execution based on the first source code. The operations can be performed via a random one of the copies of the code block. A second source code based on the updated first source code can be generated to be executed by a processor to produce an identical result as the first source code.
