摘要：Sensor information system is a specific distributed information
management system for applying sensor data and aims to effectively process,
manage, and analyze data emanating from sensor networks. Recently, with
the development of sensor networks, sensor information system encounters many
challenges, such as huge and diverse data, heterogeneous clients, scalability, and
security. In this paper, we propose an extensible and secure cloud architecture
model for sensor information system. Firstly, we describe the composition and
mechanism of the architecture model using cloud paradigm. Secondly, we
design the security solution for accessing sensor data and information services
inside the architecture. This security solution ensures legal access and use for
sensor data and information services and avoids illegal breach for user data in
the cloud environment. In particular, a certificate authority (CA) based
Kerberos protocol is proposed to provide strong identity authentication. At last,
we introduce the experiment deployment for the architecture. This architecture
fully utilizes the virtualization technology and cloud service functions and
builds an extensible cloud platform environment supplying scalable, flexible,
reliable, and secure sensor information services, which aims to solve the
challenges encountered by the present sensor information system. The simulation
experiment results show that the architecture gets high performance and stability
throughout, while keeping scalability and flexibility brought by cloud.
