Descriptions
Keylime does not enforce that the agent registrar data is the same when the tenant uses it for validation of the EK and identity quote and the verifier for validating the integrity quote. This allows an attacker to use one AK, EK pair from a real TPM to pass EK validation and give the verifier an AK of a software TPM. A successful attack breaks the entire chain of trust because a not validated AK is used by the verifier. This issue is worse if the validation happens first and then the agent gets added to the verifier because the timing is easier and the verifier does not validate the regcount entry being equal to 1,
Keylime no hace valer que los datos de registro del agente sean los mismos cuando el inquilino lo usa para la comprobación del EK y la cita de identidad y el verificador para comprobar la cita de integridad. Esto permite a un atacante usar un par AK, EK de un TPM real para pasar la comprobación del EK y dar al verificador un AK de un TPM de software. Un ataque con éxito rompe toda la cadena confiable porque un AK no comprobado es usado por el verificador. Este problema es peor si la comprobación ocurre primero y luego el agente es agregado al verificador porque el tiempo es más fácil y el verificador no comprueba que la entrada regcount sea igual a 1
