Abstract
The invention proposes a method for transmitting a message to a plurality of user entities in a network by using a multicast service, comprising the steps of encrypting a multicast message by using ciphering, and sending the encrypted multicast message to the plurality of user entities simultaneously. The invention also proposes a corresponding multicast service control device and a corresponding user entity.
Claims27
A method comprising:
- generating an authentication key based on at least one authentication parameter in a user entity;
- and
- sending a message including the authentication key from the user entity to a network control device, wherein the user entity is authenticated at the network control device based on the authentication key, and wherein the at least one authentication parameter includes a service identification identifying a requested service and a service indication including a value allocated to the service identification.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one processor, the at least one memory, and the computer program code configured to cause the apparatus to at least:
- generate an authentication key based on at least one authentication parameter in a user entity;
- and
- send a message including the authentication key from the user entity to a network control device, wherein the user entity is authenticated at the network control device based on the authentication key, and wherein the at least one authentication parameter includes a service identification identifying a requested service and a service indication including a value allocated to the service identification.
A non-transitory computer-readable medium encoded with instructions that, when executed by at least one processor, perform at least the following:
- generating an authentication key based on at least one authentication parameter in a user entity;
- and
- sending a message including the authentication key from the user entity to a network control device, wherein the user entity is authenticated at the network control device based on the authentication key, and wherein the at least one authentication parameter includes a service identification identifying a requested service and a service indication including a value allocated to the service identification.
A method comprising:
- receiving, at a network control device, a message including an authentication key from a user entity, and
- authenticating the user entity based on the authentication key, wherein the authentication key is generated by the user entity based on at least one authentication parameter, and wherein the at least one authentication parameter includes a service identification identifying a requested service and a service indication including a value allocated to service identification.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one processor, the at least one memory, and the computer program code configured to cause the apparatus to at least:
- receive, at the apparatus, a message including an authentication key from a user entity, and
- authenticate the user entity based on the authentication key, wherein the authentication key is based on at least one authentication parameter from the user entity, and wherein the at least one authentication parameter includes a service identification identifying a requested service and a service indication including a value allocated to the service identification.
A non-transitory computer-readable medium encoded with instructions that, when executed by at least one processor, perform at least the following:
- receiving a message including an authentication key from a user entity, and
- authenticating the user entity based on the authentication key, wherein the authentication key is based on at least one authentication parameter in a user entity, and wherein at least one authentication parameter includes a service identification identifying a requested service and a service indication including a value allocated to the service identification.
