=== Encrypted and Authenticated Connections
((("bitcoin network", "encrypted and authenticated connections")))((("encryption")))Most new users of bitcoin assume that the network communications of a bitcoin node are encrypted. In fact, the original implementation of bitcoin communicates entirely in the clear. While this is not a major privacy concern for full nodes, it is a big problem for SPV nodes.
((("bitcoin network", "encrypted and authenticated connections")))((("encryption")))((("authentication")))Most new users of bitcoin assume that the network communications of a bitcoin node are encrypted. In fact, the original implementation of bitcoin communicates entirely in the clear. While this is not a major privacy concern for full nodes, it is a big problem for SPV nodes.
As a way to increase the privacy and security of the bitcoin P2P network, there are two solutions that provide encryption of the communications: _Tor Transport_ and _Peer to Peer Authentication and Encryption_ with BIP-150/151.

==== Peer-to-Peer Authentication and Encryption
Two Bitcoin Improvement Proposals, BIP-150 and BIP-151, add support for Peer-to-Peer authentication and encryption in the bitcoin P2P network. These two BIPs define optional services that may be offered by compatible bitcoin nodes. BIP-151 enables negotiated encryption for all communications between two nodes that support BIP-151. BIP-150 offers optional peer-authentication that allows nodes to authenticate each other's identity using ECDSA and private keys. BIP-150 requires that prior to authentication the two nodes have established encrypted communications as per BIP-151.

As of January 2017, BIP-150 and BIP-151 are not implemented in Bitcoin Core. However, the two proposals have been implemented by at least one alternative bitcoin client, named bcoin.
