Multiple-field based code generator and decoder for communications systems

Mohammad Amin Shokrollahi, Lorenz Minder

A method of encoding data for transmission from a source to a destination over a communications channel is provided. The method operates on an ordered set of input symbols and includes generating a plurality of redundant symbols from the input symbols base ...

Methods and apparatus employing FEC codes with permanent inactivation of symbols for encoding and decoding processes

Mohammad Amin Shokrollahi, Lorenz Minder

Encoding of a plurality of encoded symbols is provided wherein an encoded symbol is generated from a combination of a first symbol generated from a first set of intermediate symbols and a second symbol generated from a second set of intermediate symbols, e ...

Cryptography based on error correcting codes

Lorenz Minder

The idea to use error-correcting codes in order to construct public key cryptosystems was published in 1978 by McEliece [ME1978]. In his original construction, McEliece used Goppa codes, but various later publications suggested the use of different familie ...

Cryptanalysis of the Sidelnikov cryptosystem

Mohammad Amin Shokrollahi, Lorenz Minder

We present a structural attack against the Sidelnikov cryptosystem. The attack creats a private key from a give public key. Its running time is subexponential and it is effective if the parameters of the Reed-Muller code allow for efficient sampling of min ...

Improved Decoding of Interleaved AG-Codes

Mohammad Amin Shokrollahi, Lorenz Minder, Andrew Brown

We analyze a generalization of a recent algorithm of Bleichenbacher et al.~for decoding interleaved codes on the

Q

-ary symmetric channel for large

Q

. We will show that for any

m

and any

\epsilon

the new algorithms can decode up to a fraction of at ...
