Optimizing Information Set Decoding Algorithms to Attack Cyclosymmetric MDPC Codes
... Abstract. The most important drawback to code-based cryptography has historically been its large key sizes. Recently, several promising ap- proaches have been proposed to reduce keysizes. In particular, signifi- cant ...

Smaller Keys for Code-Based Cryptography: QC-MDPC McEliece Implementations on Embedded Devices
... In this work we presented implementations for the McEliece cryptosystem over QC-MDPC codes for Xilinx Virtex-6 FPGAs and AVR microcontrollers. Our implementations were primarily designed for high through- ...
