Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. A private filename conversion table preserves the concatenation order needed for restoration. Together these measures guarantee confidentiality, integrity, and availability regardless of storage provider trustworthiness. Threshold Key Sharing extends this further by splitting the private key, eliminating the single point of failure.
