Despite this trend, computer users need to ensure private or personal communications remain confidential and are viewed only by the intended party. Private information such as a social security numbers, school transcripts, medical histories, tax records, banking, and legal documents should be secure when transmitted online or stored locally. One way to keep data confidential is to encrypt it. Militaries,U the governments, industries, and any organization having a desire to maintain privacy have used encryption techniques to secure information. Encryption helps to boost confidence in the security of online commerce and is necessary for secure transactions. In this lesson, you will review encryption and examine several tools used to encrypt data. You will also learn to encrypt and decrypt data. Anyone who desires to administer computer networks and work with private data must have some familiarity with basic encryption protocols and techniques. C5L3S2 You should know what will be expected of you when you complete this lesson. These expectations are presented as objectives. Objectives are short statements of expectations that tell you what you must be able to do, perform, learn, or adjust after reviewing the lesson.

  • PV204: Disk Encryption Lab
    PV204: Disk encryption lab May 12, 2016, Milan Broz <[email protected]> Introduction Encryption can provide confidentiality and authenticity of user data. It can be implemented on several different layes, including application, file system or storage device. Application encryption examples are PGP or ZIP compression with password. Encryption of files (inside filesystem or through independent layer like Linux eCryptfs) provides more generic solution. Yet some parts (like filesystem metadata) are still unencrypted. However this solution provides encrypted data with private key per user. (Every user can have own directory encrypted by own key.) Encryption of the low-level storage (disk) is called Full Disk Encryption (FDE). It is completely transparent to the user (no need to choose what to encrypt – the whole disk is encrypted). The encrypted disk behaves as the same as a disk without encryption. The major disadvantage is that everyone who knows the password can read the whole disk. Often we combine FDE with another encryption layer. The primary use of FDE is to provide data confidentiality in power-down mode (stolen laptop does not leak user data). Once the disk is unlocked, the main encryption key remains in system, usually directly in system RAM. Exercise II will show how easy is to get this key from memory image of system. Another disadvantage of FDE is that it usually cannot guarantee integrity of data. Encryption is fully transparent and length-preserving, the ciphertext and plaintext device are of the same size. There is no space to store any integrity information. This allows attacks by direct modification of ciphertext.

  • Zenworks 2017 Update 4 Troubleshooting Full Disk Encryption January 2019
    ZENworks 2017 Update 4 Troubleshooting Full Disk Encryption January 2019 This document provides troubleshooting guidelines for common problems related to ZENworks Full Disk Encryption. If, after completing the troubleshooting steps, the problem is not resolved, you should contact Technical Support (https://www.novell.com/support/) for additional help. 1 Windows PE Emergency Recovery Disk (ERD) is not working Make sure you have installed the correct WAIK architecture (32-bit vs 64-bit) (Windows 7 only) If you manually created the ERD, use the PowerShell script provided in the Cool Solutions “Windows Powershell script to create a Windows PE emergency recovery disk for ZENworks Full Disk Encryption” article. Try creating the ERD using the ADK for Windows instead of Windows AIK. See “Creating a Windows PE Emergency Recovery Disk” in the ZENworks Full Disk Encryption Emergency Recovery Reference. Try burning the ERD to a DVD rather than a CD. 2 Issues with PBA login or boot sequence After pre-boot authentication occurs, the BIOS or UEFI settings must be correctly set for Windows. With unusual DMI hardware configurations, the standard ZENworks PBA boot method and Linux kernel configuration used to provide the BIOS settings, might not work, resulting in hardware that does not function correctly or is not recognized by Windows. Beginning in ZENworks 2017 Update 2, the Full Disk Encryption Agent includes DMI menu options to repair the boot sequence for issues relating to these DMI configurations. This menu is accessible by using the Ctrl + G keyboard command at a brief point when Full Disk Encryption is shown during a device restart.

  • Disk Encryption with 100Gbe Crypto Accelerator
    Disk Encryption with 100GbE Crypto Accelerator Chelsio T6 vs. Intel AES-NI vs. Software Enabled Encryption Executive Summary Chelsio Crypto Accelerator is a co-processor designed specifically to perform computationally intensive cryptographic operations more efficiently than general-purpose CPUs. Servers with system load, comprising of cryptographic operations, see great performance improvement by offloading crypto operations on to the Chelsio Unified Wire adapter. Chelsio’s solution uses the standard crypto API framework provided by the operating system and enables the offloading of crypto operations to the adapter. This paper showcases the disk encryption acceleration capabilities of Chelsio T6 adapters by comparing its performance with Intel AES-NI and software encryption. Chelsio solution excels with 100Gbps Crypto rate performance for both encryption and decryption with less than 50% CPU usage. Chelsio’s T6 encryption solution assures complete data protection to datacenters, while providing substantial savings on CPU and memory. Chelsio Disk Encryption Offload The Terminator 6 (T6) ASIC from Chelsio Communications, Inc. is a sixth generation, high performance 1/10/25/40/50/100Gbps unified wire engine which offers crypto offload capability for AES and SHA variants. Chelsio’s disk encryption solution is a special case of data at rest protection where the storage media is a sector-addressable device. Chelsio offloads the AES-XTS mode, which is designed for encrypting data stored on hard disks where there is no additional space for an integrity field. AES-XTS builds on the security of AES by protecting the storage device from many dictionary and copy/paste attacks. Chelsio crypto driver registers with the kernel crypto framework with high priority and ensures that any disk encryption request is offloaded and processed by T6 adapter.

  • Ensuring Data Confidentiality Via Plausibly Deniable Encryption and Secure Deletion – a Survey Qionglu Zhang1,2,3, Shijie Jia1,2*, Bing Chang4 and Bo Chen5*
    Zhang et al. Cybersecurity (2018) 1:1 Cybersecurity https://doi.org/10.1186/s42400-018-0005-8 SURVEY Open Access Ensuring data confidentiality via plausibly deniable encryption and secure deletion – a survey Qionglu Zhang1,2,3, Shijie Jia1,2*, Bing Chang4 and Bo Chen5* Abstract Ensuring confidentiality of sensitive data is of paramount importance, since data leakage may not only endanger data owners’ privacy, but also ruin reputation of businesses as well as violate various regulations like HIPPA and Sarbanes-Oxley Act. To provide confidentiality guarantee, the data should be protected when they are preserved in the personal computing devices (i.e., confidentiality during their lifetime); and also, they should be rendered irrecoverable after they are removed from the devices (i.e., confidentiality after their lifetime). Encryption and secure deletion are used to ensure data confidentiality during and after their lifetime, respectively. This work aims to perform a thorough literature review on the techniques being used to protect confidentiality of the data in personal computing devices, including both encryption and secure deletion. Especially for encryption, we mainly focus on the novel plausibly deniable encryption (PDE), which can ensure data confidentiality against both a coercive (i.e., the attacker can coerce the data owner for the decryption key) and a non-coercive attacker. Keywords: Data confidentiality, Plausibly deniable encryption, Secure deletion Introduction Spahr LLP: State and local governments move swiftly to Modern computing devices (e.g., desktops, laptops, smart sue equifax 2017); Third, it will directly violate regulations phones, tablets, wearable devices) are increasingly used like HIPAA (Congress 1996), Gramm-Leach-Bliley Act to process sensitive or even mission critical data.
