A Scalable Model for Secure Multiparty Authentication
Distributed system architectures such as cloud computing or the emergent
architectures of the Internet Of Things, present significant challenges for
security and privacy. Specifically, in a complex application there is a need to
securely delegate access control mechanisms to one or more parties, who in turn
can govern methods that enable multiple other parties to be authenticated in
relation to the services that they wish to consume. We identify shortcomings in
an existing proposal by Xu et al for multiparty authentication and evaluate a
novel model from Al-Aqrabi et al that has been designed specifically for
complex multiple security realm environments. The adoption of a Session
Authority Cloud ensures that resources for authentication requests are
scalable, whilst permitting the necessary architectural abstraction for myriad
hardware IoT devices such as actuators and sensor networks, etc. In addition,
the ability to ensure that session credentials are confirmed with the relevant
resource principles means that the essential rigour for multiparty
authentication is established
Dynamic Multiparty Authentication of Data Analytics Services within Cloud Environments
Business analytics processes are often composed from orchestrated,
collaborating services, which are consumed by users from multiple cloud systems
(in different security realms), which need to be engaged dynamically at
runtime. If heterogeneous cloud systems located in different security realms do
not have direct authentication relationships, then it is a considerable
technical challenge to enable secure collaboration. In order to address this
security challenge, a new authentication framework is required to establish
trust amongst business analytics service instances and users by distributing a
common session secret to all participants of a session. We address this
challenge by designing and implementing a secure multiparty authentication
framework for dynamic interaction, for the scenario where members of different
security realms express a need to access orchestrated services. This novel
framework exploits the relationship of trust between session members in
different security realms, to enable a user to obtain security credentials that
access cloud resources in a remote realm. The mechanism assists cloud session
users to authenticate their session membership, thereby improving the
performance of authentication processes within multiparty sessions. We see
applicability of this framework beyond multiple cloud infrastructure, to that
of any scenario where multiple security realms has the potential to exist, such
as the emerging Internet of Things (IoT).Comment: Submitted to the 20th IEEE International Conference on High
