Concept
SPICE (protocole)
Résumé
In computing, SPICE (the Simple Protocol for Independent Computing Environments) is a remote-display system built for virtual environments which allows users to view a computing "desktop" environment – not only on its computer-server machine, but also from anywhere on the Internet – using a wide variety of machine architectures.
Qumranet originally developed SPICE using a closed-source codebase in 2007. Red Hat, Inc acquired Qumranet in 2008, and in December 2009 released the code under an open-source license and made the protocol an open standard.
A SPICE client connection to a remote desktop server consists of multiple data channels, each of which is run over a separate TCP or UNIX socket connection. A data channel can be designated to operate in either clear-text, or TLS modes, allowing the administrator to tradeoff the security level vs performance. The TLS mode provides strong encryption of all traffic transmitted on the data channel.
In addition to encryption, the SPICE protocol allows for a choice of authentication schemes. The original SPICE protocol defined a ticket based authentication scheme using a shared secret. The server would generate an RSA public/private keypair and send its public key to the client. The client would encrypt the ticket (password) with the public key and send the result back to the server, which would decrypt and verify the ticket. The current SPICE protocol also allows for use of the SASL authentication protocol, thus enabling support for a wide range of admin configurable authentication mechanisms, in particular Kerberos.
While only one server implementation exists, several programmers have developed new implementations of the SPICE client-side since the open-sourcing of SPICE.
spice-protocol
The spice-protocol module defines the SPICE wire protocol formats. This is made available under the BSD license, and is portable across the Linux and Windows platforms.
spice
The spice module provides the reference implementation for the server side of the SPICE protocol.
