| Abstract | 920MHz wireless multi-hop networks are networks positioned at endpoints of the highly anticipated M2M (Machine-to-Machine) systems. These networks have been proposed for use in such applications as home/ office energy management, structural health monitoring and environmental monitoring. A 920 MHz wireless multi-hop network is autonomously formed from several 920MHz wireless devices (nodes) that are geographically distributed. Therefore, remote management of the network and the nodes becomes important. One capabil i ty of the remote network/node management is the software update function. For example, maintenance of systems that operate for long periods, such as the structural health monitoring, requires software updating from a remote location using wireless communication to avoid having the workers retrieve each node. The problem is authenticating the software update sent via wireless. If a node accepts fraudulent data, the stability of the overall system cannot be guaranteed. A method to confirm the validity of multicast software updates is the digital signature technology, which can authenticate the data integrity and distribution source. However, digital signature verification will require algorithms including public key cryptography, hash function and multiple length arithmetic program to be implemented in the nodes. On the other hand, there have been proposals in which the 920MHz wireless devices use only symmetric key cryptography, used for communication data encryption and authentication, to authenticate data integrity and distribution source of multicast data . This article proposes a data authentication method based on symmetric key cryptography for authenticating software updates distributed over a 920MHz wireless multi-hop network and describes the technique’s superiority over the digital signature technology. |
