Sybil Attack

What is Sybil Attack?

Ans: Sybil is forging identities.

- It is the process of counterfeiting multiple identities with malicious intent.
- A set of faulty identities are represented through a set of large identities.

Sybil works liked man-in-the middle attack which intercept data from the sender but the different is the counterfeiting (bogus) nodes (which is vulnerable with Sybil attack) in the routing path that does not existing, then, the receiver will not get data from the sender.

This attack will be threat in the P2P environment, esp. DHT protocol.

Finally, the Sybil name comes from "the women possessed with multiple personality disorder".
