This code indicates that the server has received and is processing the request, but no response is available yet. [3] This prevents the client from timing out and assuming the request was lost. The status code is deprecated. [4] 103 Early Hints (RFC 8297) Used to return some response headers before final HTTP message. [5]
A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys.
The measurements of the ACM and BIOS code modules are extended to PCR0, which is said to hold the static core root of trust measurement (CRTM) as well as the measurement of the BIOS Trusted Computing Base (TCB). The BIOS measures additional components into PCRs as follows: PCR0 – CRTM, BIOS code, and Host Platform Extensions [a]
A TPS report ("test procedure specification") is a document used by a quality assurance group or individual, particularly in software engineering, that describes the testing procedures and the testing process.
This allows user-level code to allocate private regions of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels. [ 1 ] [ 2 ] [ 3 ] A TEE as an isolated execution environment provides security features such as isolated execution, integrity of applications executing with the TEE, and ...
Sec 6.7.5 In Estonia, the discovery of the vulnerability resulted in a state-level cyber crisis as the vulnerable smart card chip was deployed on more than 750,000 Estonian identity cards that are used daily by Estonian residents and e-residents to securely authenticate online and create digital signatures.

The endorsement key is a 2048-bit RSA public and private key pair that is created randomly on the chip at manufacture time and cannot be changed. The private key never leaves the chip, while the public key is used for attestation and for encryption of sensitive data sent to the chip, as occurs during the TPM_TakeOwnership command.
In 2019, a Berlin-based security group discovered the off-chip firmware in ordinary UEFI image files (the code that boots up the operating system), which meant that it could be easily analyzed. By using a few hand-written Python -based tools, they found that the off-chip firmware from the SPI ROM contained an application resembling an entire ...
