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. [63] 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 ...
For nearly all cryptosystems, one of the most difficult challenges is "key management" – in part, how to securely store the decryption key. If the key is stored in plain text, then any user that can access the key can access the encrypted data. If the key is to be encrypted, another key is needed, and so on.
The Security Account Manager (SAM) is a database file [1] in Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7, 8.1, 10 and 11 that stores users' passwords. It can be used to authenticate local and remote users.
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.
Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services. [1] [2] Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity ...
On devices with Windows' BitLocker disk encryption enabled, which corporations often use to increase security, fixing the problem was exacerbated because the 48-digit numeric Bitlocker recovery keys (unique to each system) required manual input, with additional challenges supplying the recovery keys to end users working remotely. Additionally ...
Billionaire Elon Musk, a key adviser to the incoming Trump administration, called for the Consumer Financial Protection Bureau to be eliminated, setting his sights on a regulator that has often ...
In April 2016, an alleged attack on RMS implementations (including Azure RMS) was published and reported to Microsoft. [4] [5] The published code allows an authorized user that has been granted the right to view an RMS protected document to remove the protection and preserve the file formatting.
