Enhancing the Security of Spin Framework by Combining Min AES with Geoencryption

Wireless sensor networks are contemporary technologies that are used for various purposes in different fields including military and security monitoring, home security, industrial processes/activities monitoring among others. The sensors used in the Wireless Sensor Networks has the capability of sensing or monitoring an environment, measure or capture data and send it wirelessly to a control unit for further processing. Such captured data needs to be secured using cryptography to prevent unauthorized interception and modification. Here we have attempted to enhance the security of SPIN (Sensor Protocol for Information via Negotiation) framework by combining the secure cryptographic algorithm MinAES with geo-encryption. The geo-encryption mechanisms are used to ensure delivering the data to the right and authorized entities at a known location only. This paper presents a strategy to implement a Hybrid Security Algorithm (MinAES + geoEncryption) to provide a secure and reliable means of accessing and delivering data between wireless network components.
