Encrypted NAS using Raspberry Pi 4

With the evolution of recent technologies like Cloud and IoT, secure file storage becomes mandatory. NAS makes use of strong cryptography to cover information facts from unauthorized users. The attackers use sledgehammers and able to deny any system service hence Denial-of-Provider assaults cannot be averted. But the proposed secure NAS system uses an advanced encrypted digital signature-based NAS Server to detect forging with less power consumption. The proposed NAS system also exhibits simplified configuration without compromising security and net server competencies. The proposed secure NAS system shows that, with the use of less expensive CPU attached to a disk, it is possible to achieve audio information storage and retrieval for sequential disk requests, and truly no penalty for random disk requests. NAS tool takes care of community file security and additionally stocks the same LAN as different devices of computers, printers, smartphones, tablets and IoT gadgets. The proposed approach also implements non-document files like audio and video files and storage performance is analyzed.
