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 ...
BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware.
Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. The term can also refer to a chip conforming to the standard ISO/IEC 11889. Common uses are to verify platform integrity (to verify that the boot process starts ...
Recall is one of the marquee features of Microsoft’s Copilot+ PCs, which is a designation for laptops that meet a specific threshold of power and capabilities and are running the latest version ...
Certificate-based encryption. Certificate-based encryption is a system in which a certificate authority uses ID-based cryptography to produce a certificate. This system gives the users both implicit and explicit certification, the certificate can be used as a conventional certificate (for signatures, etc.), but also implicitly for the purpose ...
The rogue certificate may not be revokable by real authorities, and could also have an arbitrary forged expiry time. Even though MD5 was known to be very weak in 2004, [1] certificate authorities were still willing to sign MD5-verified certificates in December 2008, [6] and at least one Microsoft code-signing certificate was still using MD5 in ...
In computer security, a side-channel attack is any attack based on extra information that can be gathered because of the fundamental way a computer protocol or algorithm is implemented, rather than flaws in the design of the protocol or algorithm itself (e.g. flaws found in a cryptanalysis of a cryptographic algorithm) or minor, but potentially ...
Public key infrastructure. A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network ...
