Bela Ban commented on JGRP-2274:
--------------------------------
[~nsawadsky] You're much more of an expert than me, but I always assumed that even a
flipped bit in an encrypted message would lead to an error when decrypting it. Apparently
that is not the case?
Is there a need for an additional protocol INTEGRITY (or CHECKSUM) that performs integrity
checking?
ASYM_ENCRYPT: deprecate sign_msgs
---------------------------------
Key: JGRP-2274
URL: https://issues.jboss.org/browse/JGRP-2274
Project: JGroups
Issue Type: Enhancement
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Major
Fix For: 4.0.12
In {{ASYM_ENCRYPT}}, signing messages means that the checksum of an encrypted message is
computed and used together with the secret key of the sender to sign the message. On the
receiver side, the public key of the sender is used to validate the signature.
However, this is redundant, as decryption of a message will fail if the contents have
been changed.
If needed, signing of messages can be done in a separate protocol.
