SDMS-based Disk Encryption Method

TL;DR

This paper introduces SDMS, a flexible disk encryption method that encrypts each sector with unique keys and updates them on data writes to enhance security for various storage devices.

Contribution

The paper presents SDMS, a novel disk encryption approach that addresses limitations of existing methods by using per-sector encryption keys and dynamic key updates.

Findings

Security performance is effectively analyzed.

SDMS improves data protection for USB and optical storage.

Flexible security control based on system requirements.

Abstract

We propose a disk encryption method, called secure disk mixed system (SDMS) in this paper, for data protection of disk storages such as USB flash memory, USB hard disk and CD/DVD. It is aimed to solve temporal and spatial limitation problems of existing disk encryption methods and to control security performance flexibly according to the security requirement of system. SDMS stores data by encrypting with different encryption key per sector and updates sector encryption keys each time data is written. Security performance of SDMS is analyzed at the end of the paper.
