Abstract
A process and a device which are characterized in that at least one first security device is arranged at one subscriber, that at least one second security device is arranged in the exchange, or alternatively, an additional device with at least one second security device is connected upstream from each exchange, the first and the second security devices being able to encode and/or decode and exchange with each other connection establishment and/or service information of the subscriber.
Claims17
A method for the transmission of confidential connection establishment and/or service information between subscriber-side data terminals and at least one digital exchange of a digital communication network, the connection establishment and/or service information being useable by the digital exchange for establishing a connection with the subscriber and/or making a requested service available, the network having at least one subscriber-side network terminator for connecting at least one data terminal, with at least one first security device arranged at a subscriber, and at least one second security device assigned to the exchange, the method comprising the steps of:
- encoding and/or decoding the connection establishment and/or service information using the first security device;
- transmitting the encoded connection establishment and/or service information between the first security device and the second security device over a separate control channel of the digital communication network;
- encoding and/or decoding the connection establishment and/or service information by the second security device;
- and
- establishing, using the digital exchange in response to the decoded connection establishment and/or service information the connection with the subscriber and/or making the requested service available.
A device for transmission of confidential and authentic connection establishment and/or service information between subscriber-side data terminals and at least one exchange of a digital communication network, the connection establishment and/or service information being useable by the digital exchange for establishing a connection with the subscriber and/or making a requested service available, the network having at least one subscriber-side network terminator for connecting at least one data terminal, the device for transmission comprising:
- at least one subscriber-side first security device arranged at a subscriber;
- and
- at least one second security device arranged in the exchange, with the first security device and second security devices for encoding and/or decoding and exchanging connection establishment and/or service information of the subscriber via a separate control channel of the digital communication network,
- wherein the at least one second security device is installed in an assembly separate from the at least one subscriber-side first security device arranged at the subscriber.
A device for transmission of confidential connection establishment and/or service information between subscriber-side data terminals at least one exchange of a digital communication network, the connection establishment and/or service information being useable by the digital exchange for establishing a connection with the subscriber and/or making a requested service available the network having at least one subscriber-side network terminator for connecting at least one data terminal, the device for transmission comprising:
- a first security device arranged at least one subscriber;
- and
- an additional device having a second security device connected upstream from the exchange, with the first security device and second security device capable of encoding and/or decoding and exchanging connection establishment and/or service information of the at least one subscriber via a separate control channel of the digital communication network, wherein the exchange in response to the decoded connection establishment and/or service information, establishes the connection with the subscriber and/or makes the requested service available.
