ABSTRACT:
An efficient method for protecting entry addresses in computer programs allows direct jumps to permissible entry addresses. The permissible entry addresses are identified with a correlation of data which are not provided within the same individual instruction. By organizing the program code, the compiler or linker ensures that only legal entry addresses satisfy this correlation.
