- Adversarial nodes can violate the protocol.
- Adversary can not break cryptography.
- The computational power of the adversary is comparable to the computational
power of the average modern PC.
Adversary in physical vicinity
- Attacker can compromise user's private key. The user is responsible for
maintaining his or her private key in a safe location.
Adversary, who has achieved social infiltration
- Temporary disturb user by sending unsolicited messages (SPAM) and/or malicious
operations. The user can quickly clean the attacker's data out and warn other
users about the malicious peer.
Local network adversary
- Adversary can have many participating nodes in the network and the nodes are
free to collaborate out-of-band.
- As any other peer in the network, adversarial nodes can see:
- who is participating with them in the network;
- subscriptions of the participants;
- unencrypted data (messages and operations) distributed via adversarial
- Adversary can block some communication routes into the network, but a node is
always able to communicate with at least one other node that is not controlled
by an adversary.
Global network adversary
- All the local network adversary can do.
- Adversary can not interrupt communications between arbitrary nodes in the
