Methods, systems, devices and products for authentication
A communication device having a controller transmits to a communication system a PKI certificate. Encrypted communications may commence responsive to receiving a public key. The communication system can have a plurality of network elements that integrate operations of a circuit-switched communication network and a packet-switched communication network.
1. A method, comprising:
receiving, by a server, a registration message from a communications device, the registration message requesting an authentication for an access to a communications network and specifying an authentication certificate associated with the communications device;
determining, by the server, a previous registration of the communications device to the communications network that was previously conducted using the authentication certificate;
determining, by the server, that the communications device is pre-registered for the access to the communications network in response to the previous registration to the communications network;
in response to the determining that the communications device is pre-registered, retrieving, by the server, a public key used for the previous registration of the communications device; and
encrypting, by the server, communications to the communications device using the public key used for the previous registration.
2. The method of claim 1 , further comprising periodically conducting a reregistration associated with the communications device.
3. The method of claim 1 , further comprising receiving an identifier associated with the communications device.
4. The method of claim 1 , further comprising receiving a unique identifier associated with the communications device.
5. The method of claim 1 , further comprising associating the authentication certificate to a subscriber.
6. The method of claim 1 , further comprising associating an address to a subscriber.
7. The method of claim 1 , further comprising decrypting the communications.
8. A system, comprising:
a hardware processor; and
a memory device, the memory device storing instructions, the instructions when executed causing the hardware processor to perform operations, the operations comprising:
receiving a registration message sent from a communications device, the registration message requesting an authentication for an access to a communications network and specifying an authentication certificate associated with the communications device;
determining a previous registration was previously conducted by the communications device using the authentication certificate;
determining that the communications device is pre-registered for the access to the communications network in response to the previous registration that was previously conducted;
retrieving a public key used for the previous registration by the communications device; and
encrypting communications sent to the communications device using the public key used for the previous registration.
9. The system of claim 8 , wherein the operations further comprise periodically conducting a reregistration associated with the communications device.
10. The system of claim 8 , wherein the operations further comprise receiving an identifier associated with the communications device.
11. The system of claim 8 , wherein the operations further comprise receiving a unique identifier associated with the communications device.
12. The system of claim 8 , wherein the operations further comprise associating the authentication certificate to a subscriber.
13. The system of claim 8 , wherein the operations further comprise associating an address to a subscriber.
14. The system of claim 8 , wherein the operations further comprise decrypting the encrypted communications.
15. A memory device storing instructions that when executed cause a hardware processor to execute operations, the operations comprising:
receiving a registration message sent from a communications device, the registration message requesting an authentication for an access to a communications network and specifying an authentication certificate associated with the communications device;
determining a previous registration was previously conducted by the communications device using the authentication certificate;
determining that the communications device is pre-registered for the access to the communications network in response to the previous registration that was previously conducted;
retrieving a public key used for the previous registration by the communications device; and
encrypting communications sent to the communications device using the public key used for the previous registration.
16. The memory device of claim 15 , wherein the operations further comprise periodically conducting a reregistration associated with the communications device.
17. The memory device of claim 15 , wherein the operations further comprise receiving an identifier associated with the communications device.
18. The memory device of claim 15 , wherein the operations further comprise receiving a unique identifier associated with the communications device.
19. The memory device of claim 15 , wherein the operations further comprise associating the authentication certificate to a subscriber.
20. The memory device of claim 15 , wherein the operations further comprise associating an address to a subscriber.
