Abstract

A találmány célja egy adatfeldolgozó rendszerben működő védtelenszoftver jogosulatlan használat elleni védelme egy önálló biztonságiegység alkalmazásával. Az eljárás során meghatároznak egy elemifüggvény készletet, amelynek függvényeit egy egységben kellvégrehajtani, továbbá egy elemi parancs készletet, majd létrehoznak avédett szoftvert azáltal, hogy kiválasztanak legalább egy algoritmikusműveletet, a védtelen szoftver forráskódú változatából előállítanakegy védett szoftver forráskódú változatot a védtelen szoftverforráskódú változatának olyan módosításával, hogy a kiválasztottalgoritmikus műveletet a védett szoftver végrehajtása során az elemifüggvényekkel kell végrehajtani. ÓThe purpose of the invention is to protect unprotected software operating in a data processing system against unauthorized use by using an independent security unit. During the procedure, a set of elementary functions, the functions of which must be executed in a unit, and a set of elementary commands are defined, then the protected software is created by selecting at least one algorithmic operation, a source code version of the protected software is produced from the source code version of the unprotected software by modifying the source code version of the unprotected software in such a way that the selected algorithmic operation must be performed with the elementary functions during the execution of the protected software.
