摘要: In this paper we present efficient implementations of McEliece variants using quasi-dyadic codes. We provide secure parameters for a classical encryption scheme based on generalized Srivastava codes, and successively convert our to CCA2-secure protocol in the random oracle model applying Fujisaki-Okamoto transform. contrast with all other code-based cryptosystems that work model, conversion does not require constant weight encoding function. results both 128-bit 80-bit security level, latter also feature an implementation embedded device.
