DOSM: A Data-Oriented Security Model Based on Information Hiding in WSNs

Xiangrong Xiao, Xingming Sun, Xinbing Wang and Lei Rao

Abstract

In this study, we propose a non-cryptology and protocol-independent technique based on information hiding, called Data-Oriented Security Model (DOSM). Instead of one layer of protection, the proposed scheme offers two-fold protection against attack. An attacker first explores whether the data in question carries any useful information and then conducts extraction on it. Information is concealed by changing some properties of the data, which does not incur extra overheads to the sensor nodes. With the help of DOSM, each forwarding node can verify the embedded marks using the source node ID in each packet. This mechanism is used to filter data in a distributed manner. It can also avoid fake and tamper attacks by terminating bad packets as soon as they are detected. The data security is guaranteed by filtering the inconsistent packets between the hidden data and its source ID, which yields low energy consumption and high reliability. The simulation results show that the proposed DOSM protects the security of data communication and achieves data authentication invisibly at small overhead expense.
