Polar codes represent a seminal breakthrough in error-correcting coding, enabling communication systems to approach the theoretical capacity of a channel with low-complexity decoding methods ...

Researchers at Skoltech have presented new generalized LDPC codes (Generalized Low-Density Parity-Check Codes, GLDPC)—a ...

The codes in question encrypt data using “trapdoor” mathematical functions that work easily in one direction but not in the other. That makes encrypting data easy but decoding it hugely ...

To break the Enigma code during the Second World War, British computer scientist Alan Turing developed a mathematical model to unlock the cipher faster than any human. Today, a group of University of ...
