This program allows users to keep sensitive files encrypted but accessible to you. Similar to a firewall or a virus scanner, TurboCrypt works in the background. Once the program is started, you enter your password once to unlock the encrypted drive, and you can then access all encrypted files stored on that drive. When unlocked, the encrypted volume simply shows up in the windows explorer as a separate drive letter. This does not mean that unlocking a volume leaves your data out in the open. Only the section of a file being used is unencrypted and passed on-the-fly to the operating system. All of this is done in the background, and is transparent to the user. That is to say, once the program is started and an encrypted volume is unlocked, the user cannot even tell that the files they are accessing are encrypted. Keep your music and movie archives on an encrypted Virtual Drive. Play files directly from the encrypted drive or save them to CDs or MP3 players just as you would if they were stored anywhere else on your computer.

It is important to secure personally identifiable and confidential information stored on portable devices such as laptops, and smartphones. Data is more appealing for thieves than the hardware itself. Encryption is the paramount protection measure to secure the confidential data. Full disk encryption (FDE) is a technique used when there is need to encrypt the hole hard drive. There are different tools available which can perform the FDE through software or hardware. This paper investigates different issues of FDE and its impact on system's performance. An insight of FDE on different data presentation issues, security attacks, performance degradation, key management, energy consumption and cost effectiveness form part of this paper. With this comparison, an easy and concise view of the different performance enhancement attributes for the FDE is provided.

The Department of Surgery at the University Of Washington School Of Medicine is faced with the challenge of providing IT security to faculty, researchers, and staff within a clinical hospital environment and at multiple sites. Many departmental faculty and staff use laptops running Windows XP and often find it necessary to travel to multiple locations throughout the day or week. Additionally, regulations such as the Health Insurance Portability and Accountability Act (HIPAA) and the Family Educational Rights and Privacy Act (FERPA) mandate the protection of protected health information (PHI) and student data that many members of the department interact with as a normal part of their work. Such data stored on departmental laptops must be secured. Concerned with data security, the department is deploying PGP Universal in order to protect this fleet of laptops with a centrally managed, whole disk encryption solution.

Abstract Disk, file, and database encryption are technologies that protect data confidentiality when stored. Full disk encryption encrypts all data on a disk except the part containing the code to unlock the rest of the disk, which is usually not encrypted. File-based encryption operates at the file level and can be done by the operating system or an application. Database encryption can be done using transparent database encryption, column-level encryption, or field-level encryption. Both full disk encryption and File-based encryption allow good protection against data leakage in the case of device theft or loss. However, due to their nature, they cannot protect against an attacker who gets her hands on a device turned on or any other intruders who can run programs on the computer.

This work investigates the state of the art in hard disk cryptography. As the choice of the cipher mode is essential for the security of hard disk data, we discuss the recent cipher mode developments at two standardisation bodies, NIST and IEEE. It is a necessity to consider new developments, as the most common cipher mode – namely CBC – has many security problems. This work devotes a chapter to the analysis of CBC weaknesses. Next to others, the main contributions of this work are (1) efficient algorithms for series of multiplications in a finite field (Galois Field), (2) analysis of the security of password-based cryptography with respect to low entropy attacks and (3) a design template for secure key management, namely TKS1. For the latter, it is assumed that key management has to be done on regular user hardware in the absence of any special security hardware like key tokens. We solve the problems arising from magnetic storage by introducing a method called anti-forensic information splitter. This work is complemented by the presentation of a system implementing a variant

<p style='text-indent:20px;'>This work introduces ${\sf {FAST}}$ which is a new family of tweakable enciphering schemes. Several instantiations of ${\sf {FAST}}$ are described. These are targeted towards two goals, the specific task of disk encryption and a more general scheme suitable for a wide variety of practical applications. A major contribution of this work is to present detailed and careful software implementations of all of these instantiations. For disk encryption, the results from the implementations show that ${\sf {FAST}}$ compares very favourably to the IEEE disk encryption standards XCB and EME2 as well as the more recent proposal AEZ. ${\sf {FAST}}$ is built using a fixed input length pseudo-random function and an appropriate hash function. It uses a single-block key, is parallelisable and can be instantiated using only the encryption function of a block cipher. The hash function can be instantiated using either the Horner's rule based usual polynomial hashing or hashing based on the more efficient Bernstein-Rabin-Winograd polynomials. Security of ${\sf {FAST}}$ has been rigorously analysed using the standard provable security approach and concrete security bounds have been derived. Based on our implementation results, we put forward ${\sf {FAST}}$ as a serious candidate for standardisation and deployment.</p>

For business users, securing data isn’t really an option – it’s mandatory. That’s never truer than for portable devices that must be encrypted to comply with the company policy or other regulations . For USB Keys, I found the <em>Carbide USB Stick</em> [1], but for external HD I was still searching an affordable solution. In this test, we evaluated the <em>Startech encrypted external Hard Drive enclosure</em> [2].

Talos is a minimal, immutable, and API-driven operating system based on the Linux kernel designed for hosting Kubernetes clusters and includes services tailored for this purpose. Talos node disk partitions contain sensitive data about the operating system and Kubernetes clusters on top of it, which must be preserved against unauthorized access. Because data exposure can result in tampering and manipulating the Talos cluster, such as gaining privileged access to the node. Therefore, encrypting the disk content and protecting the confidentiality of data is imperative for the Talos node. In the current Talos system, the key for decrypting the encrypted data is stored on a specific disk partition of the node. Thus, an adversary can access the Talos machine disk content by fetching the decryption key from the disk partition. Furthermore, he can alter the boot process's components. This thesis presents an approach, named tpm-luks-talos, to tackle the mentioned issues. It utilizes the Trusted Platform Module (TPM) on the host machine to store the decryption key and check the system integrity during the boot process. Therefore, only authorized versions of the Talos operating system and boot software can decrypt data on the encrypted disk partitions. Moreover, the thesis demonstrates unauthorized access to encrypted disks in current Talos and shows that the developed disk encryption solution works properly and protects the node disk content against an adversary that has physical access to the machine. Furthermore, the proposed solution recognizes tampering and changes in the boot software.

In the modern digital landscape, data privacy and security have become critical concerns across all sectors, affecting both enterprises and individuals. The increasing frequency of data breaches and password leaks underscores the necessity of robust cyber hygiene practices. As technology evolves, operating systems continuously introduce security updates, including encryption features, to enhance data protection. With Windows OS dominating the global market and now integrating encryption as a standard feature even for Home edition users, safeguarding data has become more pressing than ever. This thesis explores various methods for protecting data stored on physical computer devices, focusing specifically on disk encryption as a means to ensure data confidentiality and integrity. While encryption technology is widely adopted, many users lack an understanding of how to implement it effectively. The research targets individuals and organizations handling sensitive data, aiming to demystify encryption tools and provide practical guidance on their selection and usage. The study will not focus on the technical foundations of encryption algorithms but rather on the practical aspects of on-site disk encryption, with potential expansion to cloud-based solutions. The practical component involves a comparative analysis of encryption tools, evaluating factors such as speed, ease of use, availability, and accessibility.

Data storage devices such as disk drives and personal storage devices (PSD) such as flash disks are now widely used in everyday appliances. Data breaches have grown rapidly in the recent years due to compromised confidential data from storage devices. These trends forced standardization of encryption methods to secure storage devices. This paper provides a comparison review of existing encryption algorithms and modes of operations that are suitable for securing storage devices, mainly disk drives. The recent IEEE approved standard for encryption mode of operation, XTS will be evaluated in term of performance with different algorithms (AES, Twofish, and RC6). The performance of XTS mode with other modes of operations (LRW and CBC) will be explored. This detailed review and performance analysis will provide guidelines for storage devices designers to implement disk encryption.

A fixed length tweakable enciphering scheme (TES) is the appropriate cryptographic functionality for low level disk encryption. Research on TES over the last two decades have led to a number of proposals many of which have already been implemented using FPGAs. This paper considers the FPGA implementations of two more recent and promising TESs, namely AEZ and FAST. The relevant architectures are described and simulation results on the Xilinx Virtex 5 and Virtex 7 FPGAs are presented. For comparison, two IEEE standard schemes, XCB and EME2 are considered. The results indicate that FAST outperforms the other schemes making it a serious candidate for future incorporation by disk manufacturers and standardisation bodies.

We revisit the problem of Full Disk Encryption (FDE), which refers to the encryption of each sector of a disk volume. In the context of FDE, it is assumed that there is no space to store additional data, such as an IV (Initialization Vector) or a MAC (Message Authentication Code) value. We formally define the security notions in this model against chosen-plaintext and chosen-ciphertext attacks. Then, we classify various FDE modes of operation according to their security in this setting, in the presence of various restrictions on the queries of the adversary. We will find that our approach leads to new insights for both theory and practice. Moreover, we introduce the notion of a diversifier, which does not require additional storage, but allows the plaintext of a particular sector to be encrypted to different ciphertexts. We show how a 2-bit diversifier can be implemented in the EagleTree simulator for solid state drives (SSDs), while decreasing the total number of Input/Output Operations Per Second (IOPS) by only 4%.
