While several mature cryptographic frameworks exist, and have been utilized for building complex applications, developers often use these frameworks incorrectly and introduce security vulnerabilities. This stems from several challenges, including (i) an expectation that framework users understand security attacks and defenses and the subtle impact of various low level parameters, (ii) the need to...
Rateless codes can reduce retransmission costs over erasure channels. Existing routing algorithms using rateless codes assume densely connected networks and predecide the forwarder nodes, which subsequently participate in message forwarding. Using a rateless code, which is easy to analyze and implement, we propose practically implementable opportunistic message forwarding algorithms for sparsely connected...
Rateless Codes are effective in reducing the costs of retransmissions over erasure channels. Some rateless codes have systematic leading parts which have been shown in the literature to enhance their performance. The systematic part allows a node to start transmitting packets as soon as they are received without waiting for the entire multi-packet message to be decoded. This will naturally reduce...
Rateless Codes can reduce the costs of retransmissions over erasure channels. It has been shown in the literature that having a systematic part in a rateless codes enhances its performance. This paper proposes an extended systematic rateless encoding scheme to improve performance. The scheme is easy to analyze and implement. We also study several fixed and opportunistic routing protocols for a network...
