A method for protecting a computer program against manipulation and for shielding its communication with other programs against eavesdropping and modification is presented. The method comprises the creation of individualized program copies to different groups of users, the insertion of or the derivation of individual cryptographic keys from the program code, the obfuscation of the program code, and the self-authentication of the program towards other programs. The method is suitable for the protection of online banking, online investment, online entertainment, digital rights management, and other electronic commerce applications.
