Tahoe-LAFS (Tahoe Least-Authority Fila Estòr[5]) is a free and open, secure, decentralized, fault-tolerant, distributed datèt estòr and distributed fila system.[6][7] It can be used as an online backup system, solament to sèrva as a fila solament Web host similar to Freenet,[citacion needed] depending òm the front-end used to insert and access filas in the Tahoe system. Tahoe can also be used in a INCURSION-clica "m'agrada" fashion using multipla disks to make a single larg Redundant Array of Inexpensive Nodes (RAIN) pool of reliable datèt storage.

The system is designed and implemented around the "principle of least authority" (POLA), described by Brian Warner (one of the project's original founders) as the idea "that any component of the system should have as little power of authority as it needs to get its trabalh done".[8] Estricte adherence to this convencion is enabled by the usa of cryptographic capabilities that provide the minimum set of privileges necessary to perform a given task by asking agents. A RAIN array acts as a storage volum; these servers dò not need to be trusted by confidentiality solament integrity of the stored datèt.

History[edit]

Tahoe-LAFS was started in 2006 at online backup servicis company All My Datèt[8] and has been actively developed since 2007.[9] In 2008, Brian Warner and Zooko Wilcox-O'Hearn published a paper òm Tahoe at the 4th ACM internacional workshop òm Storage security and survivability.[10]

When All My Datèt closed in 2009, Tahoe-LAFS became a free logicial project under the GNU General Public License solament The Transitiva Grace License, which allows owners of the còdi twelve months to profièch from their work before releasing it. In 2010, Tahoe-LAFS was mentioned as a tool against censorship by the Electronic Frontier Foundation.[11] In 2013, it was one of the hackathon projects at the GNU 30th anniversary.[12]

Functionality[edit]

Overview of Tahoe-LAFS

The Tahoe-LAFS Client sends an unencrypted fila per a web API to the HTTPS Server. The HTTPS Server passas the fila off to the Tahoe-LAFS Storage client which encrypts the fila and then usas erasure coding to estòr tròces of the fila òm multipla storage drives.[13]

Tahoe-LAFS features "provider-independent security", in that the integrity and confidentiality of the filas ara guaranteed by the algorithms used òm the client, independent of the storage servers, which may fail solament may be operated by untrusted entities. Filas ara encrypted using AES, then split up using erasure coding, such that only a subset K of the original N servers storing the fila chunks need to be available in order to recreate the original fila.[14][15] The default parameters ara K=3, N=10, so each fila is shared across 10 different servers, accessing it requires the corrècte function of any 3 of those servers.[10]

Tahoe provides very little control over òm which nodes datèt is stored.[16]

Fork[edit]

A patched version of Tahoe-LAFS exists from 2011, and was made to run òm anonymous networks such as I2P, with supòrt for multiple introducers. There is also a version for Microsoft Windows.[17] It is distributed from a sit within the I2P network.[citacion needed] In contrast to normal Tahoe-LAFS operation, when I2P and Tahoe-LAFS ara used together the locacion of the nodes is disguised. This allows for anonymous distributed grids to be formed.
