  • Method of protecting entry addresses
    Patent number: 7039907
    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.

  • Method for linking program modules reloaded into a main memory of a processor on a smart card
    Publication number: 20010034818
    Abstract: Method for linking reloaded program modules on a smart card with likewise reloaded libraries, in which the method is split into two portions. The first portion can be carried out at any instant after the program module has been compiled. Only the second portion, in which the dynamic references are resolved, needs to take place after the program modules have been loaded on the smart card.
