Founsure 1.0: An Erasure Code Library with Efficient Repair and Update Features
Founsure is an open-source software library, distributed under LGPLv3 license and implements a multi-dimensional graph-based erasure coding entirely based on fast exclusive OR (XOR) logic. Its implementation utilizes compiler optimizations and the multi-threaded implementation to generate the right assembly code for the given multi-core CPU architectures with vector processing capabilities. Fou...
متن کاملEfficient Erasure Code for Wireless Sensor Networks
Reliable communication in Wireless Sensor Networks is hard to achieve efficiently using methods in conventional systems like Internet. End-to-end retransmission is inefficient, or in some cases impossible. Erasure code is code with which we can reconstruct m original messages by receiving any m out of n code words (n > m). Erasure code provides efficient option for achieving reliability. Erasur...
متن کاملSecure Erasure and Code Update in Legacy Sensors
Sensors require frequent over-the-air reprogramming to patch software errors, replace code, change sensor configuration, etc. Given their limited computational capability, one of the few workable techniques to secure code update in legacy sensors would be to execute Proofs of Secure Erasure (PoSE) which ensure that the sensor’s memory is purged before sending the updated code. By doing so, the ...
متن کاملA Non-MDS Erasure Code Scheme for Storage Applications
This paper investigates the use of redundancy and self repairing against node failures indistributed storage systems using a novel non-MDS erasure code. In replication method, accessto one replication node is adequate to reconstruct a lost node, while in MDS erasure codedsystems which are optimal in terms of redundancy-reliability tradeoff, a single node failure isrepaired after recovering the ...
متن کاملErasure Code with Shingled Local Parity Groups for Efficient Recovery from Multiple Disk Failures
The ever-growing importance and volume of digital content generated by ICT services has led to the demand for highly durable and space-efficient content storage technology. Erasure code can be an effective solution to such requirements, but the current research outcomes do not efficiently handle simultaneous multiple disk failures. We propose Shingled Erasure Code (SHEC), an erasure code with l...
