The ART-CRYPTO secure architectural system, designed for cyber security is always to keep the digital file/data encrypted, except for the processing period. The system's crypto engine is composed of fast key-changing apparatus (FKCA) array, which is an AES (Advanced Encryption Standard) cipher, which uses a key stream to achieve a file encryption/decryption, wherein the key stream prevents side channel attack and there is no key management. The system's identification and authorization management (IAM) distributed sub-system prevents ID fraud, malware, ransomware, spammer, and DDoS attacks. A data base (DB) with a special file structure (SFS) authorizes that a user accessing encrypted files according to user file attributes and its identification verification, prevents lowing the system's Cryptography level or having a back door design, which increases the possibility of breaching. The secure architectural system also solves the dilemma of privacy and security.
