What cypto algorithms do you need? Stream encryption and/or PKI KEX? For AES stream encrpytion there are some CPU's that directly support the crypto primitives on the silicon. For newer x86/amd64 CPU's see: http://en.wikipedia.org/wiki/AES_instruction_set A number of VIA x86 CPU's have supported a set of crypto algorithms inlcuding stream cyphers, cryptographic hashing and RSA for quite some time on their silicon. http://www.via.com.tw/en/initiatives/padlock/hardware.jsp Other than that there are some embedded crypto engines with their own (mostly MIPS based) single and multi-core CPU's. AKAIK they have a FreeBSD API and the FreeBSD MIPS port should work on at least some of them: http://www.caviumnetworks.com/ Cavium also has some plug-in crypto accelerator cards under the brand name Nitrox. IIRC they have some drivers for FreeBSD available. -- Andre
