Abstract: A computer-implemented method of tamper-protecting computer program code. The method comprises: obtaining an input representation of the computer program code; identifying a conditional program statement for causing a data processing system to selectively execute one of at least a first and a second sets of program statements when said computer program is executed by a data processing system; replacing said identified conditional program statement and the first and second sets of program statements with a set of transformed program statements to obtain obfuscated program code, wherein the set of transformed program statements is adapted to cause the data processing system to execute at least a part of each of the transformed program statements when said computer program is executed by the data processing system.
