Cryptographic Tickets!!
HydraVeil's new Anonymous Billing
Pain in the Ass
The big problem with HydraVeil previously was it required the user to buy each profile separately. Monero takes time to sync your wallet, plus the hassle of even opening it and copy-pasting data.
Or if the user used Bitcoin Layer 1 then the different profiles could be potentially connected as the same person from looking at the blockchain.
Privacy Meets Convenience
Simplified Privacy is proud to announce our new cryptographic ticketing system. The user pays a single time, and gets a number of profiles (such as 6 profiles or devices), but each profile is completely seperated from the others and even the original payment, with blinding elliptic curve cryptography.
How it Works
This all happens automatically
You don’t need to know how it works to use it. HydraVeil does it instantly in a few seconds, but if you’re curious, here’s how.
Generate
For this example, let’s say you’re getting 6 profiles. First your local client creates 6 groups of random numbers. These are called ‘commitments’, because you’re committing to using it later.
Blind them
Then HydraVeil automatically cryptographically blinds them, using a secret number called a ‘blinding factor’ that your client made. This secret number never leaves your device.
Send Blinded
HydraVeil then sends the blinded ones to the server.
Sign Blind
After you finish paying, then the billing server cryptographically signs them all, and sends it back.
Let’s compare this to PGP. When you PGP sign, you can see what you’re signing. But in this case, the server is signing blind.
Unblind
Finally, your local HydraVeil client unblinds the server’s signatures. This is done in a way that there is no way to relate the blinded and unblinded signatures, unless someone knew your secret “blinding factor”.
The unblinded signature from the server now matches the original commitment, because they were blinded and unblinded using the same secret factor. (which the server never saw)
Use Tickets
At any time in the future, you can use the ticket to activate a profile with VPN access. (or a seperate device such as a phone/router). When you do so the billing server does NOT recognize you, but can recognize that it did indeed sign it. This is the “magic” of pairing elliptic cryptography.
HydraVeil
So HydraVeil does this all automatically and instantly, to effortless give you the convenience of a single subscription, with isolated separated devices and profiles.
