An Attack on High Rate McEliece Cryptosystems Using Generalized Reed Solomon Codes with Weight Mask
Julia Lieb, Abhinaba Mazumder, Michael Schaller
Due to the insecurity of McEliece cryptosystems instantiated with Generalized Reed-Solomon codes, there have been several proposals of McEliece type systems that replace the permut…

Information-Set Decoding for Convolutional Codes
Niklas Gassner, Julia Lieb, Abhinaba Mazumder +1
In this paper, we present a framework for generic decoding of convolutional codes, which allows us to do cryptanalysis of code-based systems that use convolutional codes. We then a…

A new method for erasure decoding of convolutional codes
Julia Lieb, Raquel Pinto, Carlos Vela
In this paper, we propose a new erasure decoding algorithm for convolutional codes using the generator matrix. This implies that our decoding method also applies to catastrophic co…
