Physical attacks, introduction and application to embedded processors

Summary form only given. Physical attacks exploit the physical weaknesses of cryptographic devices to reveal the secret information stored on them. Successful attacks demonstrated in the past were both active, when the adversary tampers with the device to alter its normal behavior, or passive, when the adversary monitors side channels to infer the secret key. In view of this increasingly relevant problem, this talk introduces the most powerful physical attacks presented in the past and highlights state of the art countermeasures, focusing in particular on the embedded systems´ scenario.
