Discrete TPMs are dedicated chips that implement TPM functionality in their own tamper resistant semiconductor package. They are the most secure, certified to FIPS-140 with level 3 physical security [41] resistance to attack versus routines implemented in software, and their packages are required to implement some tamper resistance. For example ...
This key is used to allow the execution of secure transactions: every Trusted Platform Module (TPM) is required to be able to sign a random number (in order to allow the owner to show that he has a genuine trusted computer), using a particular protocol created by the Trusted Computing Group (the direct anonymous attestation protocol) in order ...
Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
TLS 1.3 (2018) specified in RFC 8446 includes major optimizations and security improvements. QUIC (2021) specified in RFC 9000 and DTLS 1.3 (2022) specified in RFC 9147 builds on TLS 1.3. The publishing of TLS 1.3 and DTLS 1.3 obsoleted TLS 1.2 and DTLS 1.2. Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0.
The Trusted Computing Group is a group formed in 2003 as the successor to the Trusted Computing Platform Alliance which was previously formed in 1999 to implement Trusted Computing concepts across personal computers. [2] Members include Intel, AMD, IBM, Microsoft, and Cisco.
The Federal Information Processing Standard Publication 140-3 (FIPS PUB 140-3) [1] [2] is a U.S. government computer security standard used to approve cryptographic modules. The title is Security Requirements for Cryptographic Modules .
The earliest work directed toward standardizing an approach providing mandatory and discretionary access controls (MAC and DAC) within a UNIX (more precisely, POSIX) computing environment can be attributed to the National Security Agency's Trusted UNIX (TRUSIX) Working Group, which met from 1987 to 1991 and published one Rainbow Book (#020A), and produced a formal model and associated ...
The TPM can impose a limit on decryption attempts per unit time, making brute-forcing harder. The TPM itself is intended to be impossible to duplicate, so that the brute-force limit is not trivially bypassed. [5] Although this has the advantage that the disk cannot be removed from the device, it might create a single point of failure in the ...
