Abstract
A computer-implemented method receives at least two unique versions of program code of a program, generates a code-based key for each unique version of the program code, generates a code-based signature for each unique version of the program using a bi-homomorphic pseudorandom function selected from a family of bi-homomorphic pseudorandom functions. Each code-based signature is generated by the selected bi-homomorphic pseudorandom function based on the corresponding code-based key. Each generated code-based signature for each unique version of the program code is incorporated into the program code of the corresponding unique version of the program.
