Privacy Network Elixxir Invites Smartphone Users to Test Private Messaging

In an age the place Google, Fb and the NSA are identified to be harvesting as a lot as our communications as they will, many individuals are involved that on-line privateness now solely exists within the historical past books. One venture attempting to handle that is the metadata-shredding platform Elixxir, led by cypherpunk innovator David Chaum, which now lets smartphone customers take a look at the community’s non-public messaging capabilities.

Metadata-Shredding Platform Launches Public Alpha

Elixxir, the most recent creation of the person often known as the “father of on-line anonymity,” David Chaum, has introduced the launch of the xx community public alpha. Maintained by a workforce of nodes run by unbiased operators, the xx community alpha represents the primary public demonstration of cmix, the transaction community that shreds metadata and gives unprecedented shopper privateness and safety.

“We’ve labored very arduous over a few years to design and develop the Elixxir privateness defending platform and now customers can entry the platform for personal communication. It’s one factor to speak about and describe such a platform, it’s fairly one other to make it accessible to be used on a smartphone. I’m very happy with our workforce for getting this finished,” stated David Chaum.

Within the weeks forward, customers may have an opportunity to take a look at the xx community public alpha for themselves. At present, choose companions are testing the general public alpha. The builders say that the general public alpha will instantly be able to processing 500 transactions per second, and so they anticipate it to scale inside weeks to 2,500-5,000 transactions per second.

The xx community public alpha nodes are run by a cross-section of chosen node operators around the globe. Operators embrace, Chainzilla, Everstake, Incrypt, Iqlusion, and Merely VC. Hand-picked by Elixxir, these node operators will contribute their experience and suggestions to inform the xx community decentralized beta later this yr.

“It’s nice to see Elixxir is obtainable publicly for prime quantity testing. I’m a supporter. Some issues about my life are confidential, that’s why I’m wanting ahead to utilizing their privateness defending platform,” commented Roger Ver, Govt Chairman of

How Elixxir Protects Users’ Metadata

Communication metadata is the data on the occasions, origins and locations of cellphone calls, emails and immediate messages, as opposed to their precise content material. It may be used in opposition to individuals by advertisers, scammers, id thieves, and even hostile governments.

The previous Nationwide Safety Company (NSA) and Central Intelligence Company (CIA) Director, Michael Hayden, famously stated in 2014 that “We kill individuals based mostly on metadata.” He defined that “metadata alone can present an especially detailed image of an individual’s most intimate associations and pursuits, and it’s truly a lot simpler as a technological matter to search large quantities of metadata than to hear to tens of millions of cellphone calls.”

In accordance to the cmix whitepaper, Elixxir is working to present safety in opposition to the harvesting and exploitation of metadata by fulfilling two core values basic to attaining true safety and privateness. The primary worth is anonymity, defending the id of individuals in actions; for instance, a message sender and recipient. Which means an adversary can’t map any enter to the corresponding output with any larger likelihood than random guessing, even when the adversary has compromised many of the system. The second worth is integrity – verifying the trustworthiness of the transaction system. This implies, for instance, that at any given level, both the system delivers all messages with out alteration, or, within the occasion of a failure, any malicious mixnode is recognized with excessive likelihood.

To attain each anonymity and integrity, the system brings collectively two key ideas: mixnets and precomputation. Mixnets, also referred to as mixing networks, have been first described by David Chaum in 1981. A mixnet lays down cryptographic guidelines for messages or transaction exercise from a set of customers to be relayed by a sequence of trusted intermediaries often known as mixnodes. These are pc servers that obtain a batch of encrypted messages, randomly permute or “combine” them, after which ship them ahead. Mixnets sometimes shield the contents of messages with public key encryption. The blending course of gives anonymity, whereas the general public key encryption gives integrity.

The primary disadvantage to conventional mixnets is that they’re gradual; the general public key encryption course of takes computer systems a very long time to carry out, making mixnets too gradual for many shopper makes use of. The cmix system is designed to resolve this drawback through the use of precomputation. Precomputation permits mixnodes to do all of the time-consuming work of public key cryptography earlier than the real-time section of dealing with messages between senders and recipients. The consequence, in accordance to the builders, is a really environment friendly sort of mixnet that enables customers to ship and obtain messages in real-time with out compromising on safety and privateness.

Mixnodes carry out the work of decrypting messages and mixing site visitors to disguise the associations between senders and recipients. The work of mixnets is carried out in three phases: setup, precomputation, and real-time. Within the setup section, mixnodes set up secret and shared public keys, which can be utilized as a seed to derive distinctive values for each session. The precomputation section is carried out as soon as for every real-time section. The mixnodes set up shared values to circumvent the necessity for public key operations through the real-time section, with every mixnode in an n-member workforce doing 1/n of the decryption work. Within the real-time section, mixnodes obtain messages, carry out the decryption work ready for with precomputation, and move the message on to the subsequent mixnode.

Cypherpunk Creator of Digital Money

David Lee Chaum is named a pioneer in cryptography and privacy-preserving applied sciences, and widely known because the inventor of digital money. In 1995 his firm Digicash, an digital cash company, created the primary digital foreign money with ecash. The famend cypherpunk as soon as lamented that web applied sciences would create a file society the place authorities would catalog data on every particular person and monitor each particular person and maintain tabs on their comings and goings.
