Hardware Security Module · PCIe
CryptoServer CSe is a Hardware Security Module (HSM) for Personal
Computers (PC) and IP-based Local Area Network (LAN) equipment
with PCIe expansion slots, developed around 2012 by the German company
Utimaco. Depending on the implementation, it can be
used for a variety of applications, including secure networking, harddisc
encryption and key management systems.
|
The actual HSM is an in-house development of Utimaco and
is the 4th generation of a family of HSMs that
started life in 1990. Amoung other things, it contains a
cryptographic processor, also known as a crypto engine or crypto heart,
that contains the building blocks for a variety of public and proprietary
encryption algorithms.
For security reasons, the HSM is cast in a strong two-component epoxy
and covered by a metal shield. It is connected to the PCIe carrier board
by means of a 30-wire flex strip. The PCIe card holds additional parts such
as a backup battery.

The HSM is responsible for real-time encryption and decryption of the data
that is offered by the external application software, but also has an on-board
random number generator (RNG) that can be used for the generation of unique
keys and signatures. Furthermore, it holds battery-backed memory
(CMOS SRAM) in which cryptographic keys and passwords can be stored.
The contents of the RAM are retained either by an on-board Lithium battery,
or by an external one that is fitted elsewhere in the computer. In case of
a security compromise, the contents of the SRAM can be purged by cutting
the power from the battery to the SRAM. This is also known as ZEROIZING.
The cryptographic processor inside the HSM supports a wide variety of
algorithms, including AES, Triple-DES, RSA, ECDSA and DSA,
each of which can
be used with various key lengths and in various modes. For further information
please refer to the document listed under [A].
A good example of the use of this HSM, is the
Utimaco CryptoServer LAN, which can be used for securing
multi-site Local Area Networks (LAN) and is approved by several governments
for sensitive data.
