WebIn this paper we describe two different DFA attacks on the AES. The first one uses a fault model that induces a fault on only one bit of an intermediate result, hence allowing us to obtain the key by using 50 faulty ciphertexts for an AES-128. The second attack uses a more realistic fault model: we assume that we may induce a fault on a whole byte. WebPara llevarlo a cabo, se creó un escenario experimental mediante un sistema distribuido con máquinas virtuales que albergan los métodos de cifrado como AES- 256, Cesar, Blowfish, para enviar datos encriptados desde una máquina origen hacia una máquina destino, y a su vez descifrar los datos encriptados. tsw 2 steam trains
