The Research and Design of 3G terminal data confidentiality services

Abstract__3GPP does not supply any active security
service interface or available security algorithm
model for the terminals, which restricts the
initiative ability and configuration ability of
security communication on the application layer
in a great deal. Focusing on this problem, we
firstly brought forward three-layer architecture
which guarantees application layer’s
communication security of 3G terminals,
researched secure confidentiality service model
which is convenient for developers, the
algorithm consultation mechanism used in the
application layer and the security algorithm
model F8* which guarantees the confidentiality
of terminal data transmission are included. It is
indicated that models and functions raised in
this article are able to be used to supply active,
visible and selectable confidentiality service for
terminals.
