System Design v1.0

Smart contract side with Secret Network:

• Receives submitted Kyber and Dilithium PKs
• Wrap random one time pad key around Kyber
• Send it to a pair of clients attached with the Kyber PK, Dilithium PK, Wallet ID of themselves and Wallet ID of the other user and Signature

Client side:

• User enters service through Tor network
• User generates Kyber and Dilithium keys locally
• Either user enters wallet ID of the person they want to chat with
• User deposits X cryptocurrency then swaps using zk proofs to Secret Network & Nym Network coins for a pool
• Both users submit Kyber and Dilithium public keys and the wallet ID of the person they want to chat with
• Both users receive a truly random one time pad key
• XOR bitwise operations using the one time pad key to transmit the message through the server of the admin (or p2p without admin)
• The receiving side decrypts the message and destroys the one time pad key
• To send a message again, both users request a truly random one time pad key again and repeat the process

Open for improved ideas & implementation.

OTP requirements:

1. Key gets destroyed
2. Truly random (RDRAND and RDSEED are Intel Secure Key technology)
3. Plaintext = key length, 32 bytes, but can be increased
4. Key is securely distributed with Kyber/Dilithium.
