Types of Attacks

Denial-of-Service (DOS)

A DOS attack sends more requests to a node than it can process (flooding). Due to the unability of the node to process all requests it has to drop requests. If all requests are treated equal, normal request might be dropped.

Replay Attack

A replay attack targets the authentication of a system. A node listens to an encrypted communication. Even it can not understand the message, it can simply send the same message (replay) to the target node in the hope that it will trigger a certain event.

Sybil Attack

A single attacker pretends to have several identities which subvert the election in a voting network and inject faulty information.
