Abstraction function for mobile handsets

摘要

Handset, computer software and method for protecting sensitive network information, available in the handset, from disclosure to an unauthorized server, by using an abstraction function module, the handset being connected to a network. The method includes receiving at the abstraction function module an encoding key from an abstraction server; receiving at the abstraction function module a request from a client or application for providing the sensitive network information from a control plane module of the handset, wherein the client or application resides in a user plane module, which is different from the control plane module, the sensitive network information is stored in the control plane module of the handset, and both the control plane module and the user plane module reside in the handset; retrieving by the abstraction function module the requested sensitive network information from the control plane module; encrypting, by the abstraction function module, the retrieved sensitive network information based on the received encoding key; and providing the encrypted sensitive network information to the client or application in the user plane module.

1. A method for protecting sensitive network information, available in a handset, from disclosure to an unauthorized server, by using an abstraction function module, the handset being connected to a network, the method comprising:
receiving at the abstraction function module an encoding key from an abstraction server; receiving at the abstraction function module a request from a client or application for providing the sensitive network information from a control plane module of the handset, wherein the client or application resides in a user plane module, which is different from the control plane module, the sensitive network information is stored in the control plane module of the handset, and both the control plane module and the user plane module reside in the handset; retrieving by the abstraction function module the requested sensitive network information from the control plane module; encrypting, by the abstraction function module, the retrieved sensitive network information based on the received encoding key; and providing the encrypted sensitive network information to the client or application in the user plane module.
