Underwater acoustic sensor networks (UASNs) are widely used in many application. However, the underwater acoustic channel poses many challenges for reliable data transmission protocol design. In this paper, we propose a new data transmission protocol based on Fountain codes and Selective-repeat ARQ scheme (FSR-ARQ). The new approach utilizes the packet error correction ability of rateless code and...
Commitment schemes are fundamental building blocks in cryptography, and have wide applications in constructing various protocols. Non-malleable commitment considers concurrent executions of a commitment scheme against a man-in-the-middle adversary. In this paper, we investigate non-malleability of statistically hiding commitment schemes, and present the first concurrent non-malleable statistically...
For communications and networking channels, coding techniques are widely used to correct errors in corrupted messages. The “Quality of Protection” (QoP) that can be provided via error correction directly affects the “Quality of Service” (QoS) experienced by users. The errors are commonly assumed to be substitution or erasure errors. Such systems rely on perfect synchronization so that no bit is deleted...
