The large amount of information exchanged grows exponentially and a lot of it is constituted by sensitive data, it must be protected to prevent its fraudulent use. A correct application of Cryptography prevents malicious access, so that information can be protected. Studying the vulnerability/robustness of the security is, then, an essential aim in order to guarantee that protection. On the other hand, the field of use is so wide that it is necessary, in this case, for low resource environments and focused on device implementations with high density programmable electronic. The aim of this TFG is to analyze the behaviour of stream ciphers implemented on FPGAs against active attacks, that is inyecting faults in the clock line during the operation of Trivium stream ciphers. Through the analysis of active attack techniques, an attack system is presented with the aim of analyzing the Trivium cipher vulnerability and behavior, implemented on FPGA, against active fault attacks.
