Code-based cryptography employs error-correcting codes as the basis for secure public-key schemes, leveraging the intrinsic difficulty of decoding a random linear code. The foundational McEliece ...

For non-planar graphs, such solutions are computationally intractable," explained the researchers. The algorithm relies on the Kac-Ward formalism, a mathematical method that allows exact computation ...

Low-Density Parity-Check (LDPC) approaches Shannon-limit performance for binary field and long code lengths. However, performance of binary LDPC code is degraded when the code word length is small. An ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...
