Post-quantum cryptography for privacy and security of the Internet

Vulnerabilities of the public key infrastructure currently used to secure the Internet are enhanced with the development of quantum computers; with privacy, security and cryptocurrency severe implications. Distribution of information is a key solution for the future security infrastructures. Quantum computers' development road map predicts a serious threat on today's encrypted data within less than a decade, this is an opportunity to reconsider the security of the Internet, based on the public key infrastructure architecture.

Having all information in a particular site or sent over a particular channel is a big risk for privacy. Information distribution can serve us today in efficient solutions for data in motion and data in rest. Ownership of information is preserved when sending a credit card number, sending a random number through email and a random number through SMS, such that their xor is the actual number. Storing photos in your own computer/server may risk data leakage and/or ransomware attacks, storing in Google Drive and alike, yield a trust in a single entity (and all the employers of the entity) and lose of data ownership, hence, a multi-cloud solution, each cloud storing random numbers is preferred.
Blockchain distributed trust complements the above solutions allowing private logic contracts.
