Communicating data securely within a mobile communications network
First Claim
1. A method of communicating data securely within a wireless communications network, comprising the steps of:
- receiving a first authentication request from a mobile station;
providing a first key to said mobile station in response to said authentication;
receiving a second authentication request from a database server, said second authentication request further including said first key provided by said mobile station and a particular database record to which said mobile station is requesting access;
determining whether said mobile station has authority to access said particular database record; and
in response to said affirmative determination, instructing said database server to provide information associated with said requested database record to said mobile station wherein said information is encrypted; and
providing said mobile station with a second key enabling said mobile station to decrypt said information received from said database server using said second key.

Abstract
Data is securely stored encrypted within a database server or portal within a public network. A wireless device first registers with an authentication center maintained separately from the database server to obtain a session key. The obtained session key is then used by the wireless device to request particular data from the database server. The database server, in response to said request, queries the authentication center to verify the authenticity of the wireless device. The authentication center verifies the received session key with the identified wireless device and provides the wireless device with a second group key. The authentication center further instructs the database server to comply with the data request and provide the wireless device with the encrypted data. The wireless device thereafter uses the received group key to decrypt the received data from the database server and is allowed access to the secured data.

13. An authentication server for communicating data securely within a wireless communications network providing wireless service to a wireless device and communicatable within a database server associated within a data communications network, comprising:
-
a session key generator for generating a particular session key to be used by said wireless device in response to said wireless device registering with said authentication server;
a database record for correlating a particular database record with a particular first encryption key;
wherein said database record further correlating identities of authorized users with said particular database record;
an encryption key generator for generating a second encryption key to be provided to said wireless device for decrypting certain information associated with said database record stored within said database server. - View Dependent Claims (14, 15, 16, 17, 18)
