COMMUNICATING DATA SECURELY WITHIN A MOBILE COMMUNICATIONS NETWORK

摘要

Data is securely stored encrypted within a database server or portal within a public network. A wireless device firs t registers with an authentication center maintained separ ately from the database server to obtain a session key. Th e 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 wi reless device. The authentication center verifies the rece ived session key with the identified wireless device and p rovides the wireless device with a second group key. The a uthentication center further instructs the database server to comply with the data request and provide the wireless device with the encrypted data. The wireless device therea fter uses the received group key to decrypt the received d ata from the database server and is allowed access to the secured data.
