Definitions

  • the invention relates to a method for the activation of customer-relevant access authorizations in conditional access systems for the reception of chargeable services, such as pay-TV, digital radio data services in DAB, DVB, Swift, video-on-demand and any digital services that are broadcast via radio systems.
  • chargeable services such as pay-TV, digital radio data services in DAB, DVB, Swift, video-on-demand and any digital services that are broadcast via radio systems.
  • security modules such as smart cards, on which security algorithms and / or customer-specific authorizations in the form of software programs and data are stored, according to the preamble of claim 1.
  • Security modules in the form of smart cards are already used in many areas in which it is necessary to grant people or machines authorization-dependent or conditional access [Conditional Access (CA systems)] to data or programs or other machines, if the set conditions or permissions are met (e.g. Pay TV).
  • CA systems Consumer Access
  • Other typical areas of application for smart cards are electronic means of payment, GSM telephony or digital radio data services in DAB, DVB, Swift and video-on-demand in the future.
  • conditional access systems take place almost exclusively on the basis of smart cards in chip card technology. These smart cards contain a stored security algorithm and customer-specific authorizations for receiving paid data services.
  • the problem for conditional access systems is that a provider of services, a content provider, certainly wants to reach more than one customer, but again not all of them. Only authorized customers should be able to receive a service. These are those customers who meet certain defined conditions by purchasing entitlements, for example that they have paid the monthly subscription fee. Radio systems are used to transmit such authorizations. The problem thus arises that access to certain information distributed via broadcasting systems should be controlled, but which in principle can be received by anyone.
  • Securing access to such information e.g. Pay-TV, by means of conditional access systems, is done by scrambling, which is encryption of the program content, by storing
  • Terminal devices for receiving a pay TV program are usually the so-called set-top boxes or decoders.
  • other end devices are also possible, for example mobile receiving devices, PC cards or PCMCIA modules, or the end device can be integrated into the television.
  • the activation of smart cards in broadcasting systems particularly when used in devices for mobile reception of services without point-to-point connection, such as with the telephone, is problematic because of the lack of reception guarantee. Only the activation enables a customer to use the service they want immediately after purchasing a card. However, the sender of an activation usually has no information as to whether the activation has actually reached the customer.
  • Activation does not take place if radio reception is impossible for the device used, e.g. due to building shielding in underground garages or e.g. in cases where a radio network required to send authorizations has not yet been expanded to such an extent that reception of authorizations by a So-called EMM message (Entitlement Management Messages) is not possible nationwide.
  • EMM message Entitlement Management Messages
  • a controlled initial activation with feedback is very safe and also enables instant collection for the activated service at the time of its acquisition.
  • Program contents are scrambled by the data being encrypted by an encryption algorithm under the control of a so-called control word CW.
  • the algorithm used in digital television based on the MPEG-2 standard in Europe is mainly the DVB Common Scrambling Algorithm. However, other algorithms are also possible, such as, for example, DES or Triple DES (cf. Bruce Schneier, Angewandte Kryptographie, Wiley, 1996).
  • ECM Entitlement Controll Messages
  • CW new control words
  • Entitlement Management Messages are used to set and change receive authorizations that are stored in the decoder or in the security module. EMM messages must be sent to the customer's individual address (or the decoder or the security module). Customer address and EMM messages must be protected against change; it must be ensured that only the program provider can generate EMM messages. Individual addresses always appear unencrypted in the EMM messages; Duplication protection can only be achieved by means of supplementary information that is stored so that it cannot be read by the customer. This is the personal key (PK) that is linked to the customer address. EMM messages are about the same Broadcasting system as the user data sent.
  • PK personal key
  • EMM messages are not permanently linked to the program content, but to the logical address of the customer's end device or that of the security module, so that EMM can be addressed to individual customers or to groups of customers.
  • a return channel can also be available, either manually (call a service center) or automatically (e.g. connection from the decoder to the transmission center via TCP / IP) becomes.
  • Permissions can change if e.g. the cost accounts of customers are not settled, which can result in the blocking of a reception authorization, for example.
  • EMMs can also be used to activate services on smart cards for the first time or to reactivate them.
  • the authorizations in the security module such as a smart card, must be reset.
  • chip cards are mostly used as security modules, which are not permanently connected to the end device, but can also be removed from it and exchanged.
  • the invention is therefore based on the object of specifying a method by means of which a chip card of an authorized customer can be made individually addressable for modification for pay services, the pay services also being intended to be used for mobile customers.
  • the solution to the problem is that at the request of a service provider, i.e. an institution authorized to issue or sell security modules, such as a T-point to a service center responsible for authorization control, e.g. Data service center in the DAB, the service center for indirect activation either by telephone or data transmission system sends an EMM activation signal specifically assigned to this security module to the service provider and there this EMM activation signal for the relevant service in a control device of the service provider feeds in and is given to the security module and the security module is activated with this EMM activation signal via the control device or, in the case of direct activation, the service center with the aid of a data transmission service in a digital radio service such as the DAB single-frequency network transmits the specifically assigned EMM activation signal to the security module of the sends inquiring customers and unlocks them.
  • the invention is based on the advantage that the activation of a service on a security module such as a smart card by means of the respective

  • the service center grants the authorization after payment of the corresponding data service fee by means of the above-mentioned direct or indirect activation via the smart card-specific EMM.
  • a control device installed at the service provider confirms the activation of the security module, such as a smart card, for the service in question.

  • the caller When a call is made, it is ensured that the caller can also receive the EMM, since the fact that a GSM connection has been established can be used to infer the possibility of DAB reception.

Abstract

L'invention concerne un procédé pour l'activation d'autorisations d'accès de clients dans des systèmes à accès conditionnel pour la réception de services médiatiques payants à l'aide de modules de sécurité, tels que des cartes à puce, sur lesquels sont enregistrés des algorithmes de sécurité ou des autorisations clients sous forme de programmes logiciels. Sur demande d'un prestataire de services, comme un point de vente télécom ou une autre institution habilitée à vendre des modules de sécurité, un centre de service responsable du contrôle des autorisation envoie, au moyen d'un téléphone ou d'un système de télétransmission de données en cas d'activation indirecte, un signal d'activation EMM affecté spécifiquement à ce module de sécurité au prestataire de services. Le signal d'activation EMM pour le service médiatique concerné est alors introduit dans un appareil de contrôle du prestataire de services et transmis au module de sécurité et le module de sécurité est activé avec ce signal d'activation EMM par l'intermédiaire de l'appareil de contrôle. En cas d'activation directe, le centre de service utilise un autre service de transmission de données dans un réseau de radiodiffusion numérique, tel que le réseau sur onde commune de radio numérique, pour envoyer au module de sécurité du client demandeur le signal d'activation EMM spécifiquement affecté, puis active ce module de sécurité.
