Crypto Acceleration on FreeBSD
As more and more services on the internet become
cryptographically secured, the load of cryptography
on systems becomes heavier and heavier. Crypto
acceleration hardware is available in different
forms for different workloads. Embedded communications
processors from VIA and AMD have limited acceleration
facilities in silicon and various manufacturers
build hardware for accelerating secure web traffic
and IPSEC VPN tunnels.
This talk gives an overview of FreeBSD's crypto
framework in the kernel and how it can be used
together with OpenSSL to leverage acceleration
hardware. Some numbers will be presented to demonstrate
how acceleration can improve performance - and how
it can curiously bring a system to a grinding halt.
Philip originally started playing with crypto
acceleration when he saw the "crypto block" in one
of his Soekris boards. As usual, addiction was
instant and by the grace of the "you touch it, you
own it" principle, he has been fiddling the crypto
framework more than is good for him.
