On the Decoding Failure Rate of QC-MDPC Bit-Flipping Decoders
code-based cryptography MDPC codes iterative decoding
2018/12/20
Quasi-cyclic moderate density parity check codes allow the design of McEliece-like public-key encryption schemes with compact keys and a security that provably reduces to hard decoding problems for qu...
In the field of collusion-resistant traitor tracing, Oosterwijk et al. recently determined the optimal suspicion
function for simple decoders. Earlier, Moulin also considered another type of decoder:...
Tally-based simple decoders for traitor tracing and group testing
traitor tracing Tardos code collusion
2016/1/6
In this paper we construct a score system from the Neyman-Pearson hypothesis test (which is known to be the most powerful test possible) into which we feed all the evidence available to the tracer, in...
Generalised tally-based decoders for traitor tracing and group testing
traitor tracing group testing fingerprinting
2015/12/29
We propose a new type of score function for Tardos traitor tracing codes. It is related to the recently introduced tally-based score function, but it utilizes more of the information available to the ...
Implementation Of Decoders for LDPC Block Codes and LDPC Convolutional Codes Based on GPUs
Implementation Of Decoders LDPC Block Codes LDPC Convolutional Codes GPUs
2012/4/17
With the use of belief propagation (BP) decoding algorithm, low-density parity-check (LDPC) codes can achieve near-Shannon limit performance. LDPC codes can accomplish bit error rates (BERs) as low as...
Sequential, successive, and simultaneous decoders for entanglement-assisted classical communication
simultaneous decoders entanglement-assisted classical communication Quantum Physics
2011/9/29
Abstract: Bennett et al. showed that allowing shared entanglement between a sender and receiver before communication begins dramatically simplifies the theory of quantum channels, and these results su...
Demonstration of Hybrid Using ±π/2- and 0/π-Phase-Shifted SSFBG En/decoders in the 4×10Gbit/s OCDMA system
Fiber optics communications Fiber Bragg gratings Optical security and encryption
2015/5/26
We develop the novel ±π/2-phase-shifted SSFBG en/decoders (31-chip 640Gchip/s)and verify the improved security performance. We also demonstrate the mixed use of 0/π- and ±π/2-phase-shifted SSFBG en/de...
A Discrete Time Markov Chain Model for High Throughput Bidirectional Fano Decoders
Discrete Time Markov Chain Model Bidirectional Fano Decoders
2010/11/18
The bidirectional Fano algorithm (BFA) can achieve at least two times decoding throughput compared to the conventional unidirectional Fano algorithm (UFA). In this paper, bidirectional Fano decoding i...
Secure Lossy Source Coding with Side Information at the Decoders
Secure Lossy Source Coding Side Information Decoders
2010/12/9
This paper investigates the problem of secure lossy source coding in the presence of an eavesdropper with arbitrary correlated side informations at the legitimate decoder (referred to as Bob) and the ...
