I saw light the release of the anonymous network i2p 1.9.0 and C ++-client i2pd 2.43.0 . I2P is a multilayer anonymous distributed network operating on top of a regular Internet, actively using through (end-to-end) encryption that guarantees anonymity and isolation. The network is built in P2P mode and is formed thanks to resources (throughput) provided by network users, which allows you to do without the use of centrally controlled servers (communication within the network are based on the use of encrypted unidirectional tunnels between the participant and PEER-AMI).
in the I2P network You can anonymously create web sites and blogs, send instant messages and email, exchange files and organize a P2P network. To build and use anonymous networks for client-server (sites, chats) and P2P (exchange of files, cryptocurrency) applications, I2P clients are used. The basic i2p client is written in Java and can work on a wide range of platforms, such as Windows, Linux, MacOS, Solaris, etc. I2PD is an independent I2P client in C ++ and spreads under the modified BSD license.
The new version of I2P has completed the development of a new SSU2 transport protocol based on UDP and a remarkable increase in performance and security. Tests are implemented for checking SSU2 on the side of feasts and relay. The SSU2 protocol is included by default in the assemblies for Android and ARM, as well as at a small percentage of routers based on other platforms. In the November release, it is planned to include “SSU2” for all users. The introduction of SSU2 will fully update cryptographic stack, get rid of the use of a very slow Elgamal algorithm (for end-to-end encryption, a bunch of ECIES-X25519-AEAD-RATCHET instead of elgamal/aes+sessiontag ) , reduce overhead costs compared to SSU and improve the operation of mobile devices.
