Delegation of signing rights for emerging 5G networks

Abstract

Summary 5G mobile networks are promising to offer mobile users unrivaled experiences with infinite networking capability at any period and from anywhere. However, it appears unnecessary and impractical for the customers and servers to be connected permanently in wireless networks because battery life is a bottleneck in such kind of networks. Therefore, the authorized entity needs to delegate its right to others in order to ensure the services available. This paper aims to address the issue of delegating authentication in 5G networks by proposing a new proxy signature scheme with efficient proxy signing operations. Concretely, we present a new and efficient proxy signature algorithm whose unforgeability can be reduced to the well‐known discrete logarithm assumption. In the proposal, the original signer delegates his signing right by signing an exposure‐free chameleon hash value on the warrant, and the proxy signer can generate a proxy signature on a message only by calculating a chameleon hash collision between the warrant and the message. This approach is computationally cost‐effective for the proxy signer. Further analysis of the new scheme demonstrates that it offers the desirable properties of delegation of signing sights.

() Moreover, the increased networking communications may also address a broader extent of applications by utilizing new technologies,() such as Heterogeneous Networks with Small Cells (HetNets‐WSC), Massive Multiple‐Input/Multiple‐Output (MIMO), Machine to Machine (M2M), Software‐Defined Networking (SDN), and the Internet of Things (IoT). With these anticipated characteristics, an empowered network may increase the wireless service scope as well as chances of security risks.…”

Recent advances in security and privacy in large‐scale networks

“…The ninth paper, ‘Delegation of Signing Rights for Emerging 5G Networks’ , Ge et al address the issue of delegating authentication in 5G networks by proposing a new proxy signature scheme. In their proposal, the original signer delegates his or her signing right by signing an exposure‐free chameleon hash value as a warrant, and the proxy signer can generate a proxy signature on a message only by finding a chameleon hash collision instead of calculating a new digital signature, which can dramatically reduce computation cost of the proxy signer.…”
