> In SPARK-13331, support for AES encryption was added to the Spark network library. But the authentication of different Spark processes is still performed using SASL's DIGEST-MD5 mechanism. That means the authentication part is the weakest link; since the AES keys are currently encrypted using 3des (strongest cipher supported by SASL), Spark can't really claim to provide the full benefits of using AES for encryption.
> We should add a new auth protocol that doesn't need these disclaimers.
