Superscreen uses an asymmetric cryptographic algorithm to ensure that no one can access your information as it is being bi-directionally transmitted between your phone and your Superscreen. Your Superscreen app creates 2 keys, 1 of which is held on the app in your phone, and the other of which is sent to your Superscreen hardware device.
The first key is made up of a modulus and an encryption exponent (securely stored on your phone Superscreen app), while the second key contains the same modulus with a decryption exponent (securely stored on the your Superscreen hardware device), such that the keys have a common element in the modulus, with different elements in their exponents.
Additionally, Superscreen uses Wi-Fi Direct connection such that the owner’s Superscreen and phone operate in a security domain that is independent from any infrastructure network. The user has protection of the security features certified under the WPA2, but is managed separately from the security system in the AP-based network (home, enterprise, and hotspot). Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.
Publically available data streamed from the net, not specific to the user, does not warrant and will not be encrypted. For this public data we will SALT cryptography.
