Its called Privategrity and looks very promising.

Once made public  it will be  studied  by NSA  tell  they find weakness  in it  like everything else  . Its just  like that Hornet Browser they say is so much better then tor they want release it  to the public  in fear of NSA  will find back doors  . There's no such thing as being 1000% anonymous online . You're  contented to the www.

Fookin right m8 my opinion now is do what you feel safe doing online VPN or not they got your ass if they want it ..

Back in the day  bro we never cared we  done what we wanted  in the chatrooms even though NSA  was on there they wasn't after us no ways that was before we  had all this encryption.   encryption is a two edge sword . it can hide you're ip  from most people but it can make you be watched when you didn't do anything that bad  in some places like  china  using it is against  the law .

And if they find weaknesses the developer is going to fix them.  The only problem I see with privategrity is the backdoor I dont care if its carefully monitored the fact that it is a backdoor and can be used maliciously only problem I see with it.

Backdoor no matter how many hoops is still a backdoor, and that will lead a lot of people to not use it.

 

Also, backdoor or not, this is still a centralized service, and in this day and age we really need decentralized solutions that can't be shutdown or hacked in 1-9 locations to bring the whole thing down.

Interesting read about it here https://news.ycombinator.com/item?id=10850192

 

What I get  about  reading info about it.

1. It already has a built in backdoor

2,  David Chaum is a patient freak so  it will likely be patented  and there be no way for someone to fork off it  and remove backdoors .

3. it takes 9 admins  to run it and it will be government controlled.

 

You may as well tell the nsa to make you a centralized sever  no wonder  hes not came up with a good idea in 20 years  ,  a patient troll  made a centralized sever  with a builtin back door another bad idea .

 

[Holmes]

Like I said the backdoor he wants to embed into the cryptography is the one item I abhor unless he changes his mind about putting a backdoor in it chances are its destined to fail.  I was thinking the same sh*t they could be blackmailed or some government agency could pay them to give up the password or key.

David Chaum announces new PrivaTegrity network, his own take on Tor and I2P, but with better encryption

 

The cMix communication model

 

David Chaum, the father of many encryption protocols, has revealed a new anonymity network concept that aims to fix many of Tor's current problems, both in the legal and technical department.

Many scientists have tried to fix Tor in the past with concepts like I2P, HORNET or Vuvuzela. David Chaum's advantage is the fact that the Tor Project actually copied his work in the past, implementing an evolved version of one of his anonymity protocols called Mix Network, also used by Bitcoin's creators.

Mix Network (sometimes called Mixing Network) relies on encrypting data in layers as it passes through intermediary servers. The concept was first published in 1979 and was later used as the basis for the Onion protocol, on which the Tor network was built.

This past Wednesday, on January 6, 2016, Mr. Chaum presented himself at the Real World Cryptography Conference in Stanford, where he revealed a project on which he had worked for the past two years alongside other cryptography experts from four universities in the US, UK, and Holland.

His paper, called "cMix: Anonymization by High-Performance Scalable Mixing," presents an evolution of the Mix Network concept, called cMix, which took into account Tor's advancements, but also addressed some of the issues governments and regular users had with its implementation. The researchers plan to use this new cryptography protocol to build their own, more secure PrivaTegrity network, as an alternative to Tor.

An incredibly simplified explanation of cMix

According to their research paper (page 1 - Section I, and page 4 - Chapter III-D), for each communications path established in a cMix network, the message sender creates connections with a series of trusted servers, with which it shares a series of keys.

When the sender sends out a message, its data is multiplied with all the keys. As the message passes through each server, it is divided with each server's corresponding key, but also multiplied again by a random number. Messages are then stored randomized in each server's buffer.

When the data needs to be retrieved and sent to the receiver, each server will retrieve the message from its random position, divide out the random numbers, and then multiply it with the recipient's keys.

When the data arrives on the recipient's computer, their keys are used to divide the data and decrypt the message.

Better anonymity than on Tor

According to Mr. Chaum, by moving most of the computational operations to the server, instead of the client, cMix achieves the same transfer speeds as Tor, but unlike its predecessor, it is not vulnerable to a series of "tagging" attacks.

Tagging attacks rely on compromising Tor nodes, which on their own allow attackers to tag input slots with their output location. By using cMix's setup, the protocol is not vulnerable to these type of attacks, unless the malicious entity compromises all nodes that participated in the encryption process.

Additionally, researchers said that, in PrivaTegrity, tagging attacks are also blocked by how users set up keys with network nodes.

"PrivaTegrity aims to provide privacy at a technical level that is not penetrable by nation states," the researchers claim. "PrivaTegrity implements a new approach to user identification requiring each user to provide a small but different type of identifying information to each mix node."

But...

This identification may include anything from passphrases to images, from phone numbers to email addresses. "A user reveals comparatively little to any single node, but collectively the nodes possess significant identifying information," researchers revealed.

While its encryption protocol is incredibly strong, the researchers also said that data about users is not 100% anonymous.

In an interview with Wired, Mr. Chaum revealed that, to prevent cybercrime and other nefarious groups from using their network, the researchers behind this initiative are planning to create a PrivaTegrity Council.

This council will provide access to data about users to law enforcement, but only for those who use the network for criminal activities. This council will have nine members from across the world, and all have to agree to release information about users to any government inquiring for data.

With the rising trend of government requesting backdoors to encryption protocols, Chaum and his associates are trying to move the backdoor from the hands of governments to an international council.

While technically as fast as Tor and even more secure from third-party attacks, admitting that a group of nine people get to play judge over your anonymity may deter users from embracing PrivaTegrity.

Currently, Chaum and his team are working on a smartphone IM app to test their PrivaTegrity network.
