摘要：In emergency situation, wireless sensor networks can be subject to various attacks aimed to mislead information or to paralyze the network. In such context, security is an essential requirement to ensure efficient communication within sensor network. Most of the proposed security protocols for WSNs fix only a part of security issues and are based on authentication or cryptography. In this paper, we propose to enhance framework Ad-M-QOS-DS with a new adaptive secure capability. The new feature brings more confidentiality, data integrity and availability within malicious context. The new security layer ASATE combined three approaches: Authentication based on MAC Filtering, Trust index based on the criticality of events and adaptable Encryption depending on the type of messages spread on the network and the present risk.
