I2P 0.9.2 description
I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other.
The network itself is strictly message based (ala IP), but there is a library available to allow reliable streaming communication on top of it (ala TCP). I2P is an application that allows users to compunicate via IP address.
All communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ("destinations") are cryptographic identifiers (essentially a pair of public keys).
To anonymize the messages sent, each client application has their I2P "router" build a few inbound and outbound "tunnels" - a sequence of peers that pass messages in one direction (to and from the client, respectively).
In turn, when a client wants to send a message to another client, the client passes that message out one of their outbound tunnels targeting one of the other client's inbound tunnels, eventually reaching the destination.
Every participant in the network chooses the length of these tunnels, and in doing so, makes a tradeoff between anonymity, latency, and throughput according to their own needs.
The result is that the number of peers relaying each end to end message is the absolute minimum necessary to meet both the sender's and the receiver's threat model.
What's New in This Release:
Major Changes:
· SSU: Fix several problems in our UDP transport, to improve efficiency and reliability for connection setup. Also improve defenses against various types of bad input.
· UPnP: Updated our library to fix several issues, should work for more routers now
· Transport: Improve performance in both our TCP and UDP transports, to benefit high-bandwidth routers
· Crypto: The thresholds and number of ElGamal/AES Session Tags delivered are now much more flexible, which should lessen protocol overhead and reduce stalls caused by dropped tags.
· I2PSnark: Add DHT support, not yet enabled by default, will do further testing and plan to enable by default in 0.9.3.
Bug Fixes:
· Fix various issues affecting memory usage and performance on high-bandwidth routers
· Fix problems in UDP for routers using a reduced-MTU connection, e.g. a VPN
· Fix i2psnark bug that prevented a completion announcement to the tracker
· Fix a lock contention problem in i2ptunnel
· Fix some OSX installation issues
· Remove uses of ...
