Abstract

The invention can be used in crypto systems for encrypting and decrypting information distributed through communication media and the ether, in particular for digital TV for receiving and displaying audio video information. Instead of transmitting encrypted content information, the accessory part of information is distributed through public communication media. The short encrypted content is distributed on a smart card with processor. Additional encryption by an individual user's key is provided. The system allows to protect from unauthorized displaying information transmitted in accordance with the pre-announced program, e.g. movies, recorded programs, informational data, such as data bases, etc. The method and the system imply that a user should purchase in advance the right to watch or to have an access to data.
