Windows 11 is the latest major release of the Windows NT operating system and the successor of Windows 10. Some features of the operating system were removed in comparison to Windows 10, and further changes in older features have occurred within subsequent feature updates to Windows 11. Following is a list of these.
In October 2017, it was reported that a flaw enabled private keys to be inferred from public keys, which could allow an attacker to bypass BitLocker encryption when an affected TPM chip is used. [64] The flaw is the Return of Coppersmith's Attack or ROCA vulnerability which is in a code library developed by Infineon and had been in widespread ...
A common purpose of cold boot attacks is to circumvent software-based disk encryption. Cold boot attacks when used in conjunction with key finding attacks have been demonstrated to be an effective means of circumventing full disk encryption schemes of various vendors and operating systems, even where a Trusted Platform Module (TPM) secure cryptoprocessor is used.
Multiple keys: Whether an encrypted volume can have more than one active key. Passphrase strengthening: Whether key strengthening is used with plain text passwords to frustrate dictionary attacks, usually using PBKDF2 or Argon2. Hardware acceleration: Whether dedicated cryptographic accelerator expansion cards can be taken advantage of.
Windows 8 and later have native support for TPM 2.0. Windows 7 can install an official patch to add TPM 2.0 support. [93] Windows Vista through Windows 10 have native support for TPM 1.2. The Trusted Platform Module 2.0 (TPM 2.0) has been supported by the Linux kernel since version 4.0 (2015) [94] [95] [96] [97]
Challenge–response password recovery mechanism allows the password to be recovered in a secure manner. It is offered by a limited number of disk encryption solutions. Some benefits of challenge–response password recovery: No need for the user to carry a disc with recovery encryption key. No secret data is exchanged during the recovery process.
Key management takes place within the hard disk controller and encryption keys are 128 or 256 bit Advanced Encryption Standard (AES) keys. Authentication on power up of the drive must still take place within the CPU via either a software pre-boot authentication environment (i.e., with a software-based full disk encryption component - hybrid ...
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
