The contents of the phone are encrypted, and your communication with other users of Quasar IV phones are encrypted as well using public and private keys. Android phones can already be encrypted using a standard setting, but Chao says Quasar does it better.

'Instead of having a third-party hosting or giving out the public key, we have managed to create what we call a seed public key matrix that produces all possible keys up to 10^77 of keys for all the users out there,' Chao told Ars in a phone interview. The chip contains both the public key matrix and the user's private key. When initiating communications with another user, the Quasar IV uses the recipient's identity to calculate their public key and encrypt the data. Once received, the user decrypts it with their private key. AdvertisementĪll e-mails, text messages, and VoIP calls can be encrypted, he said. Quasar IV can still communicate with users of other phones and devices, but not in an encrypted manner. If you don't use a Quasar phone, you're basically doomed, QSAlpha CTO Ben Vaughan said in one of the company's videos. Experts: Proprietary encryption can't be trusted 'Every time you visit a website, every time you send an e-mail, and every time you make a phone call, you are exposing yourself to criminal activity,' he said. While QSAlpha's general descriptions of its technology sound reasonable, claims of being 'un-hackable' are bound to draw derision from security experts. After talking to Chao, Ars reached out to two experts to get neutral opinions on Quasar IV, speaking to Steve Thomas, who recently discovered a critical flaw in Cryptocat, and cryptographer Jean-Philippe Aumasson. 'The only thing you need to know about this phone is 'proprietary encryption.' If you aren't aware, this means it's probably broken. Don't trust me, just Google 'proprietary encryption,'' he told Ars in an e-mail.
