Improved Identity Management Protocol for Secure Mobile Cloud Computing

Due to the rapid spread of smart phones and SNS (social network services), the use of Internet applications has increased and their need for bandwidth has begun to exceed the capacity of 3G networks. This has caused a reduction in speed and service quality and has underscored the need for network companies to invest in additional bandwidth. The increase in mobile network users has caused identity management problems for mobile service providers. This paper proposes improved IDM3G [8] to solve user ID management and security problems on mobile internet application services over 3G networks along with an additional authentication management protocol. The proposed I©÷DM protocol breaks up loads, which are allowed by the existing IDM3G protocol's mutual authentication via mobile operator process, by sending some parts to an Internet application service provider to enhance mobile and ID management at the service provider and by reducing the network and process loads from information handling and packet transmission. This optimized protocol should improve the performance of the 3G mobile network.
