Abstract

A decentralized and distributed secure home subscriber server is provided. First data can be sent representing a first nonce string to a mobile device; and in response to receiving second data representing the first nonce string and a second nonce string, a communication channel can be established with the mobile device as a function of the first nonce string.

First claim

1 . A device, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
sending first data representing a first nonce string to a mobile device; and
in response to receiving second data comprising a database tuple stored as crypto-currency transactional data in a database device of distributed database devices, wherein the database tuple represents the first nonce string and a second nonce string, facilitating establishing, by the device, a communication channel with the mobile device based on the first nonce string.

2 . The device of claim 1 , wherein the first data is encrypted using a public key associated with the mobile device.

3 . The device of claim 2 , wherein the public key associated with the mobile device is received from the distributed database devices.

4 . The device of claim 3 , wherein the public key associated with the mobile device is received in response to sending an identifier associated with the mobile device to the distributed database devices.

5 . The device of claim 4 , wherein the identifier and the public key are stored as the database tuple to the database device, the database tuple is encrypted using a private key associated with a mobile network operator device, and the mobile network operator device facilitates storage of the database tuple to the database device.

6 . The device of claim 1 , wherein the second data is encrypted using a public key associated with the device.

7 . The device of claim 6 , wherein the operations further comprise decrypting the second data using a private key associated with the device.

8 . The device of claim 7 , wherein the operations further comprise sending third data representing the second nonce string to the mobile device.

9 . The device of claim 8 , wherein the third data is encrypted with the public key associated with the mobile device.

10 . A method, comprising:
receiving, by a system comprising a processor, first data representing a first nonce string; in response to receiving a database tuple stored as crypto-currency transactional data comprising a cell identifier associated with a base station device and a first encryption key associated with the base station device, sending, by the system, to a mobile device second data representing the first nonce string and a second nonce string; and facilitating establishing, by the system, a communication channel between the mobile device and the base station device in response to receiving third data comprising the second nonce string from the mobile device.

11 . The method of claim 10 , wherein the first data is received in response to sending, by the system, an international mobile subscriber identifier to the base station device.

12 . The method of claim 10 , further comprising using, by the system, a second encryption key to decrypt the first data to obtain the first nonce string.

13 . The method of claim 12 , wherein the second encryption key is stored to an integrated circuit device associated with the system.

14 . The method of claim 12 , further comprising using, by the system, the first encryption key associated with the base station device to encrypt the second data.

15 . The method of claim 12 , further comprising using, by the system, the second encryption key to decrypt the third data to obtain the second nonce string.

16 . A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
receiving first data representing an international mobile subscriber identifier string associated with a mobile station device; based on the international mobile subscriber identifier string, searching a storage device to retrieve a first database tuple stored as transactional blockchain data comprising the international mobile subscriber identifier string and a key associated with the mobile station device; and sending second data representing the key associated with the mobile station device to a base station device.

17 . The machine-readable storage medium of claim 16 , wherein the operations further comprise sending third data representing a second database tuple to the mobile station device.

18 . The machine-readable storage medium of claim 17 , wherein the second database tuple comprises a cell identifier associated with the base station device and another key associated with the base station device.

19 . The machine-readable storage medium of claim 16 , wherein the first data is received from the base station device.

20 . The machine-readable storage medium of claim 16 , wherein the international mobile subscriber identifier string is associated with a subscriber identification module card.
