Petroleum industrial control software always uses traditional USB encryption dogs or other hardware methods to encrypt the software, but for the hardware's easy to copy, lose and to confuse which causes the software operators' many inconvenience, and also caused the extra cost expense to the software supplier. In view of this phenomenon, this paper proposes a soft encryption method Based on RSA digital signature on the basis of fully investigating the current soft encryption methods, and carries on a shell processing according to the application characteristics of petroleum industry control software. This protection scheme provides a kind of thinking to the software encryption way of other industry software.
