Secure Execution Partitioning of Weak Devices
MetadataShow full metadata
The performance of weak embedded devices like cellular phones and sensors in Wireless Sensor Network (WSN) can be improved significantly by partitioning execution between the nodes in the network. Idle nodes can help busy nodes by executing their code which can lead overall system to achieve high performance gain with increased lifetime. At the same time, security policy of the system can be compromised by exposing private data of a particular node to an external node. Also, attackers can obtain execution flow and critical data by listening to the network because these devices communicate all the time to help each other. This research studies an optimized framework for distributing and completing tasks securely in a network of weak embedded devices. Analysis of security and performance will be performed on this framework to verify its security, effectiveness and efficiency.
