Reliability has become one of the most vital requirements in wireless sensor networks (WSNs). One efficient way to increase the reliability is by using erasure coding techniques such as Reed-Solomon/Cauchy Reed-Solomon. The problem is the time required for encoding and decoding the data words, especially when large amount of data need to be sent like in complex WSN applications. In this paper, we...
Generalized Reed Solomon (GRS) codes are widely used for reliability applications in computer systems like data storage and communications and thus, efficiency in encoding and decoding of GRS codes is very important for system performance. Though GRS codes provide enormous flexibility, they are computationally expensive since calculations happen in Galois fields. In this paper, we present an algorithm...
In this paper, we study the effects of channel errors on security and decoding error probability of three encryption systems where encrypted message is sent and eavesdropped over binary symmetric channels (BSC). The three systems are all based on Data Encryption Standard (DES) in cipher feedback (CFB) mode. They are DES only (DC), DES concatenated with Reed Solomon encoding (DCRS), and DES concatenated...
