|Error correcting codes for reliable and secure transmissions|
Forward error correcting (FEC) codes are traditionally used for improving performance of digital transmissions. At present, the state-of-the-art in the FEC codes scenario is constituted by Low Density Parity Check (LDPC) code. The research unit is developing a number of theoretical and simulation tools for the design and optimization of these codes. The group has expertise also on more classical FEC schemes and collaborates with the European Space Agency (ESA) in several activities concerning the analysis and verification of the codes proposed for inclusion in the CCSDS standards. FEC codes can also be used for encryption and authentication purposes, within solutions that are potentially able to resist the advent of quantum computers, and are therefore prone for future secure implementations. In particular, the group has proposed a variant of the so called McEliece cryptosystem, based on LDPC codes, that has been proven to overcome some drawbacks of the original proposal. Further solutions are under investigation for extending the adoption of FEC codes to new schemes for digital signature.
