Full Title
Hardware Protection offered by Hardware Security Modules (HSM see FIPS 140) or management chips.
Context
- This wiki page focuses on Hardware Protection of cryptographic keying materiel where all secret cryptographic operations occur without releasing any private cryptographic materiel.
- On 2020-11-17 [1] Microsoft announced that they planned to enable the Pluton design on chips from Intel and AMD.
- Both Intel and ARM enable secure enclaves on their Microprocessor to protect security.
- Latest version as of 2019-05-22 is FIPS 140-3, version 3. Future versions will likely be issued as Common Criteria.
- The TPM (Trusted Platform Module) version 1 was a purely hardware version of protection that was offered only as a stand-alone chip. With version 2 defined as software, it can be (and often is) included in any Trusted Execution Environment.
- The first on-board Hardware Protection was provided by a product from the Intel Data Security Operation that was built, but never shipped. The DSO was disbanded on 1996-01-11. The devices was based on the i386 design with full memory bus encryption so that it could use the normal memory bus in DMA mode. Paul England made it clear in 2010 that Microsoft fought to prevent Hewlett Packard from implementing a board with the chip installed.
- HSM modules were created in the early 1990's to be installed in IBM and other mainframe computers.
- Original Hardware protection was on dedicated data transmission devices with the symmetric keys delivered by hand to each device. This was the basis for FIPS 140 first issue and the Trusted Network Interpretation for the National Computer Security Center MCSC-TG-005 dated 1987-07-31.
Problems
When hardware contains software, and particularly when it contains firmware, it no longer has the same level of protection that a purely hardware solution offers. For example the Apple T2 chip has been hacked and cannot be fixed in the field.[2]
Solutions
- YubiHSM 2 (2023) fits into any spare USB B slot, which means it does not fit on portable devices. It offers a hardware solution for protecting Certificate Authority root keys from being copied by attackers, malware, and malicious insiders. It offers superior cost effective security and easy deployment making it accessible for every organization. It offers a higher level of security for cryptographic digital key generation, storage, and management, for organizations running Microsoft Active Directory Certificate Services.
Broad Categories
- Smart Cards use a 6 or 8 pin silicon chip to create and protect private key material. They typically only support one Cryptography algorithm and one user.
- Hardware Wallets typically support the Cryptography algorithms used by Bitcoin and similar digital currencies.
- Hardware Security Modules have a variety of designs, but typically sit in computer centers connected to one hardware processor, often on the memory buss. They have rich support paradigms which often includes a network protocol for key sharing.
