Subject [jira] [Commented] (HAMA-565) Support Encryption for Hama in the Clouds
Date Fri, 27 Apr 2012 16:28:51 GMT


Thomas Jungblut commented on HAMA-565:

I would also be interested in it. But Hama is just transferring plain binary, so if you catch
a whole message to another peer, you could get the raw data back with a bit of reverse engineering.

A very simplistic approach would be to try a telnet on the RPC communication port of a peer
and look at the results, or sniffing the stuff with tcpdump.

> Network traffic among the peers in the cloud is currently done without any encryption
maybe revealing sensitive data.
> I just came across a compression codec for Hadoop making it possible to encrypt stuff
with RSA/DSA public/private keys.
> Since we have compression and we can also support Hadoop codecs we can encrypt messaging
between servers.
