Abstract

A találmány célja egy adatfeldolgozó rendszerben működő védtelenszoftver jogosulatlan használat elleni védelme legalább egy önállóbiztonsági egység alkalmazásával. Az eljárás egy védett szoftverlétrehozására szolgál, úgy, hogy a védtelen szoftver forráskódúváltozatában kiválasztanak legalább egy algoritmikus műveletet, avédett szoftver forráskódú változatát előállítják, hogy a védtelenszoftver forráskódú változatát módosítják, úgy, hogy a legalább egyalgoritmikus műveletet szétbontják, így a védett szoftver végrehajtásasorán több különálló lépés történik, mégpedig az egység rendelkezésérebocsátunk legalább egy operaadust, amellyel végrehajtjuk azalgoritmikus művelet funkcióját, és az egység segítségével a legalábbegy eredményt az adatfeldolgozó rendszer rendelkezésére bocsátják. ÓThe purpose of the invention is to protect unprotected software operating in a data processing system against unauthorized use by using at least one independent security unit. The method is used to create a protected software, by selecting at least one algorithmic operation in the source code version of the unprotected software, creating a source code version of the protected software, modifying the source code version of the unprotected software, in such a way that at least one algorithmic operation is broken down, so that during the execution of the protected software, there are several separate steps takes place, namely, we provide the unit with at least one operand, with which we perform the function of the algorithmic operation, and with the help of the unit, at least one result is provided to the data processing system.
