摘要： A method of protecting a computer program (16) running on a computer apparatus (10) from piracy. The computer program (16) includes a code module (18) which performs an application and code which defines a plurality of blockades (20). Each blockade is associated with a parameter which determines activation of the blockade. Once activated, each blockade changes the functionality of the application compared to that pertaining prior to activation of the blockade. Blockades activate at different times. Each blockade requires at least one program update to be executed to deactivate that blockade. Updates can be installed manually or automatically. Preferably, the computer program is authorised as being a genuine copy of the program before receiving a program update.

摘要： A cryptographic algorithm such as AES/Rijndael involves a non- linear substitution step wherein an input byte is replaced by an output byte according to an S-box. This could be done using a look-up table. In the invention the contents of the S-box is given as input to the cryptographic method together with a cryptographic key to be used in the cryptographic method. Content can be encrypted using the chosen key and the chosen S-box as input before distribution. In a system comprising a server configured to execute the method and a plurality of clients, the clients may have the same chosen S-box or may have mutually different S-boxes.
