FIELD: information technology.SUBSTANCE: method comprises steps of: encoding a digital program to link said digital program with an authentication agent by packing the digital program and authentication agent into single digital content. Said authentication agent includes a program code executed by a device, wherein the device can reproduce said digital program and execute the program code. The program code is configured to authenticate the device when executed in the device; and provide said device with digital content which includes said digital program and said authentication agent. Said digital program is encrypted via a first encryption algorithm, and the decryption key of the fist encryption algorithm is encrypted via a second encryption algorithm and is stored in the authentication agent.EFFECT: performing device authentication and authorisation independent from an authentication server.14 cl, 7 dwg |
