If the blocking is minor then a VPN is fine. If DPI is being used (and VPNs are an issue) then use a VPN with an SSL wrapper like stunnel. You can use someone like airvpn or setup your own VPN server. Make sure you have leak protection client side. The torrent clients can leak too. Put the client in a VM guest. Establish the VPN on the host OS or (more complex) via a guest VM via and internal network. You can use pfsense for the VPN client guest.
BitTorrent requires a torrent file containing a cryptographic digest ofevery piece of the content to allow the verification of pieces during thedownload. Large torrent files put a strain on the Web servers distributingthem, and cannot be directly included in RSS feeds or gossiped around.
A related problem is the use of large piece sizes. To keep the size of atorrent file small (as to not overload the Web servers) the number of hashesfor a content file is being kept small. For large files this implies that thepiece size over which digests are calculated must go up (up to 2MB pieces areused). The large piece sizes affect the ability of peers to barter pieces.Only when a piece has been completely received and verified using the digestmay it be traded with other peers. This means that it may be some timebefore a node starts bartering with others.
We propose a minimalistic design that does not affect the existing BitTorrentprotocol and clients very much. The design is backwards compatible in thesense that clients supporting the Simple Merkle Hash extension can still bemade to process regular torrent files easily.
>From the content we construct a hash tree as follows. Given a piece size,we calculate the hashes of all the pieces in the set of content files. Next,we create a binary tree of sufficient height. Sufficient height means that thelowest level in the tree has enough nodes to hold all piece hashes in the set.We place all piece hashes in the tree, starting at the left-most leaf, seefigure. The remaining leaves in the tree are assigned a filler hash value of0 (see Discussion). Finally, we calculate the hash values of the higher levelsin the tree, by concatenating the hash values of the two children (again leftto right) and computing the hash of that aggregate. This process ends in ahash value for the root node, which we call the root hash. The hashingalgorithm used is SHA1, as in normal torrents.
When a seeder starts it uses the information in the Merkle torrent and thefile set to reconstruct the hash tree and registers itself with the trackerusing the hash value of the info part of the Merkle torrent, as usual(see Discussion).
Upon receipt of a Tr_hashpiece message, the receiver recomputes the roothash using the hashlist and compares it to the root hash in the Merkletorrent. If they match, all the hash values are saved in the receiver's ownhash tree, such that they can be passed on to others when the piece isdownloaded from this receiver. When all subpieces have come in, the piece ischecked using the hash from the hash tree.
Using the hash of the info part for registering at the tracker meansthat for a given content-file set, the swarm that use a conventional torrentfile and the swarm that uses a Merkle torrent will be disjunct. The infohashvalue is different, hence the swarms are known under different identifiers atthe trackers.
In theory we can create one swarm. In that swarm, new clients could servepieces to old clients. For the new clients to benefit from the old clients,however, we need to add some way for the new to obtain the hashes required tocheck a piece. Designing a fool proof solution for this problem is nottrivial.
NEW YORK, NY / ACCESSWIRE / October 13, 2015 / PeerLogix, Inc. (the "Company") (LOGX), an advertising technology and data aggregation provider, today announced the top five scary movie downloads on torrent. The PeerLogix software platform not only tracks Torrent download data, but also serves as a unique audience measurement tool to understand past, present and emerging consumer trends.
The Welsh Triads (Welsh Trioedd Ynys Prydein, literally "Triads of the Island of Britain") are a group of related texts in medieval manuscripts which preserve fragments of Welsh folklore, mythology and traditional history in groups of three. The triad is a rhetorical form whereby objects are grouped together in threes, with a heading indicating the point of likeness. For example, "Three things not easily restrained: the flow of a torrent, the flight of an arrow, and the tongue of a fool".
A file that is transmitted via BitTorrent, on the other hand is first divided into chunks. Each of those chunks is then hashed using SHA-1, i.e. a checksum is generated, by the torrent creator. The hashes are given to each BitTorrent client prior to the download - usually contained in a .torrent file. As the file chunks are then downloaded by the client, they are first hashed by the client itself, and compared with the previously received hash. Only if the hash matches, meaning that the chunk contains exactly the same bytes as the expected chunk, is it accepted. It is a practical impossibility to manufacture altered chunks that have malicious content, but retain their original hashsum.
Since these hashes are shared with you prior to the download, presumably from a trusted source, it is harder (to impossible) to manipulate the expected files in transit when received via BitTorrent compared to a HTTP download. The provider can distribute the torrent, which is a small file, from a single secured server via HTTPS under his own control, and the hashing mechanism will provide a validation for the actual download.
If on the other hand, your hashes or torrent file are tampered with prior to the download, or due to a MitM attack if downloading the torrent itself via HTTP, then the checksum validation offers no security.
Lastly, there is a way how the checksum mechanism can be circumvented by an attacker if he has access to the file prior to the hashsum generation, i.e. prior to the original creation of the torrent. It is then possible for an attacker to modify the file in such a way that some of the file's content can later be substitute with pre-engineered code during transmission of the torrent without being detected by the SHA-1 hashsum check, despite being different to the file that was originally checksummed.
If the adversary is trying to trick you into getting a malicious document, what's the difference between downloading the document via HTTP vs. downloading the document via BitTorrent using the .torrent file?
With HTTP, the power to intercept your internet connection is enough for the adversary to fool you into accepting a malicious forgery. This is because HTTP does nothing whatsoever to verify authenticity of data received on the internet: it is like a particularly naive clerk who lets the guys in high-visibility vests into the secret control room because they said they had a job to do.
With HTTP, the power to run a mirror is enough for the adversary to fool you into accepting a malicious forgery. They just serve you the forgery when you ask for it, and you have no way a priori to distinguish the forgery from the real document.
Your assumption that this claim is true is flawed. They are both susceptible to interception. One could claim that BitTorrent is less so since it's decentralized, but simply downloading the .torrent manifest is enough to reconstruct what requests you will make to other peers anyway.
At least .torrent files have a cryptographic hash calculated over them to protect against corruption. This doesn't really support the assertion in your question though, because if this .torrent is served over HTTP, then it's equally susceptible to being manipulated over the wire.
As discussed in other answers, .torrent files contain a cryptographic digest of the file data. This means that they are as trustworthy as the files they describe, no more or less. (The hash function is SHA-1, so collision attacks are possible, but a collision attack requires that the files themselves be maliciously generated or modified, and I would say that the files and the .torrent are both equally untrustworthy in that case.)
The advantage of the .torrent file is just that it's much smaller. Web sites that provide Linux installation images and the like generally can't afford to serve disk images to everyone for free. When they do provide the option to download them directly, it's usually donated bandwidth on third-party servers that they don't control. In contrast, they can afford to provide .torrent files to everyone from their own server, which they may have better reason to trust.
If you download an image from a random third-party server (even if it's not an official mirror), and compute a cryptographic digest (ideally SHA-256 or better) of the image, and it matches the published digest on the official server, that's just as good from a security perspective as using a .torrent file downloaded from the same official server over the same protocol. If that protocol is really HTTP (as opposed to HTTPS), then both options are pretty insecure, but neither one is significantly worse than the other.
That's rather common, e.g. gaming services like Battle.net used to "steal" bandwidth by making their downloaders (unconscious) uploaders. Debian explicitly mentions reduced bandwidth usage on their servers as reason to use bittorrent.
Yes, BitTorrent has a reasonably secure mechanism to ensure you get what you're supposed to get. However, you're still downloading that torrent file via HTTP--if you're going to be MITMed they can just replace the torrent file with one that points to their malicious content. 2ff7e9595c
