How does the Clone process work?
Cuvex allows you to select the multi-signature option, you only have to indicate how many people are mandatory to decipher and the user flow will indicate when you must give the device to each person, so that they establish their own Password.
Up to 6 people can participate in a multi-signature process.
When it is intended to visualize the private key or seed encrypted and stored on an NFC card, it will be necessary to enter each of the signatories. it´s not will be necessary for each signer to enter their Password in the order in which these user signed during the encryption process.
How does the Clone process work?
The Cuvex device will ask you to approach the issuer card, the card you want to clone. The device will ask you to approach a blank receiver card and will clone on the new card an exact copy and with the same security of the issuing card. It's that simple!
How does the Update process work?
Important, do not start the device update process until you download the new firmware version to your smartphone.

What secure element does Cuvex use?
Reducing costs in this vital part of our device was not an option. We have selected the best, from the best manufacturer that any electronics professional knows. Cuvex mounts STM32U585, the highest quality version marketed by the manufacturer ST. Designed specifically for military-grade hardware encryption, it features its own encryption accelerator engine (AES, PKA, OTFDEC). Our device does NOT store anything in its secure element, but we also decided to implement it in the hardware so that it does not perform any of its temporary tasks of encryption or decryption in a standard memory. In addition, the device is already prepared for future evolutions where the functionalities demanded by the Blockchain industry can be implemented.
How many decryption attempts does Cuvex allow?
If you enter your password wrong a second time, the device enters a time-locked process in which it supports a new retry. Please make sure you enter your Passwords correctly.
Why the best entropy for seed creation is the Coin and Dice?
All entropy calculated by software demands your trust in that software.
If it is you who, completely independent of the software, generate the necessary 23 words by throwing heads or tails and all four dice, you will have no doubt about the quality of the seed that you have created yourself.
Although the seed generation softwares are assumed to be a high quality of entropy, none can equal to this completely unique manual process that you are going to create.
What happens if Cuvex disappears and my device damages? How will I be able to decrypt my Cuvex cards in the future?
Cuvex has published its source code on GitHub, being verifiable, visible and editable. Anyone can compile the Cuvex Firmware and run it on similar hardware.
