Abstract(in English) | Non-malleable codes protect communications against adversarial tampering of data, which can be seen as a relaxation of error-correcting codes and error-detecting codes. Recently, Rasmussen and Sahai (ITC2020) explicitly constructed non-malleable codes in the split-state model using expander graphs. In this work we extend their construction by means of bipartite expander graphs. In particular, we instantiate our construction based on some specific bipartite graphs, obtaining explicit non-malleable codes which reduce the encoding space cost in comparison with the codes by Rasmussen and Sahai. |
