Sensor network security emerging trends

Abstract:-

Sensor networks are expected to become a major tool for various security and/or surveillance applications. Although it is expected that eventually they may be used as fully autonomous systems, in a more realistic scenario, sensors network are devices supporting human decisions with data that have been preliminarily analyzed and interpreted.

The paper reports security of sensor network with the
1. Secure Aggregation.
2. Secure multiparty computation.
3. Multimedia processing in which.
- Secure Scalable coding and progressive encryption.
- Watermarking/steganography.
4. Threshold secret sharing.
5. Visual cryptography.
6. Encryption and compression.
7 I- frame coding and Sign scrambling.

Using these techniques we are trying to become our network (wireless sensor network) secure.
The presented results are an example of a distributed sensor network combining reasonable energy requirements with a relatively high level of intelligence in the paper. Sensor networks promise viable solutions to many monitoring problems. However, the practical deployment of sensor networks faces many challenges imposed by real-world demands. Sensor nodes often have limited computation and communication resources and Battery power. Moreover, in many applications sensors are deployed in open environments, and hence are vulnerable to physical attacks, potentially compromising the sensor’s cryptographic keys.
One of the basic and indispensable functionalities of sensor network is the ability to answer queries over the data acquired by the sensors. The resource constraints and security issues make designing mechanisms for information aggregation in large sensor networks particularly challenging.
