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 ...
The FIPS 140-2 standard is an information technology security approval program for cryptographic modules produced by private sector vendors who seek to have their products certified for use in government departments and regulated industries (such as financial and health-care institutions) that collect, store, transfer, share and disseminate ...
The 140 series of Federal Information Processing Standards ( FIPS) are U.S. government computer security standards that specify requirements for cryptographic modules . As of October 2020, FIPS 140-2 and FIPS 140-3 are both accepted as current and active. [ 1] FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became ...
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.
A secure cryptoprocessor is a dedicated computer-on-a-chip or microprocessor for carrying out cryptographic operations, embedded in a packaging with multiple physical security measures, which give it a degree of tamper resistance. Unlike cryptographic processors that output decrypted data onto a bus in a secure environment, a secure ...
An HSM in PCIe format. A hardware security module ( HSM) is a physical computing device that safeguards and manages secrets (most importantly digital keys ), performs encryption and decryption functions for digital signatures, strong authentication and other cryptographic functions. [ 1] These modules traditionally come in the form of a plug-in ...
AES instruction set. An AES (Advanced Encryption Standard) instruction set is a set of instructions that are specifically designed to perform AES encryption and decryption operations efficiently. These instructions are typically found in modern processors and can greatly accelerate AES operations compared to software implementations.
A trusted execution environment ( TEE) is a secure area of a main processor. It helps the code and data loaded inside it be protected with respect to confidentiality and integrity. Data confidentiality prevents unauthorized entities from outside the TEE from reading data, while code integrity prevents code in the TEE from being replaced or ...
