BCM5823 LINUX DRIVER

Unlimited security association SA support via system memory and a multi-threaded DMA engine utilizes system memory to maximize throughput in real-world applications. Might be worth checking Solaris references as well. Furthermore, performance of the BCM can easily be scaled to increase both IPsec and public-key processing performance. The first step in finding out if you’re using hardware acceleration is ensuring that the driver is listed there, and that it’s the highest priority among them. The BCM CryptoNetX Security Processor, in both the Mbps and Mbps versions, is sampling today, and production quantities are expected to be available in the third quarter of Scalable to 1 Gbps of IPsec processing?

How did you find that out? Finding out what’s available in the Kernel. Except where otherwise noted, content on this wiki is licensed under the following license: Support for the bit key AES at Mbps provides much stronger IP security at a mid-range performance point, which is required by embedded firewalls, VPN appliances, VPN-enabled routers and access devices used for securing confidential e-Commerce transactions and data transfers over the Internet.

Linux is a registered trademark of Linus Torvalds. Able to scale to 1 Gbps with multiple devices, the BCM addresses a very broad range of performance points.

New ‘IP security processor’ features Linux support

This article was originally published on LinuxDevices. Irvine, CA — press release excerpt — Broadcom Corp. You may find out what engines are available, along with the enabled algorithms, and configuration commands by running openssl engine -t -c:.

For openssl support, the llinux supported are skcipher and shash. Ability to prefetch packet contexts, minimizes the performance degradation when processing llinux packets. VIA Padlock security engine. The BCM supports bit key AES, the most recent Government-approved encryption algorithm necessary for IPsec-based firewalls and VPN appliances, which is being rapidly deployed by network equipment manufacturers.

Not all devices have a hw crypto supporting chip. There are patches for Ljnux as well. You should not concern yourself with theoretical bla,bla but find out how a certain implementation performs in the task you want to do with it! The driver is still considered experimental. Here is OpenSolaris driver for Broadcom crypto chips.

Comments are the property of their submitters. The chip comes with an extensive embedded software development kit bcm58223 is compatible with Broadcom’s other CryptoNetX security chips, enabling manufacturers to build a range of security solutions using one software platform. In this case, it would be: Table of Contents Cryptographic Hardware Accelerators. You won’t be llinux to extrapolate this information from other benchmarks.

Broadcom’s development kit includes a reference design and a cryptographic software library, supporting BSD, Linux, and VxWorks. Content originally published on LinuxDevices. Discussion about hardware accelerated crypto.

Cryptographic Hardware Accelerators

For IPsec, which is done by the Kernel, this will tell you if you are able to use the crypto accelerator. You probably want enough performance, that you can use your entire bandwidth. Two BCMs provide up to 1 Gbps performance? For other uses, openssl needs to be checked. Unlimited security association SA support via system memory and a multi-threaded DMA engine utilizes system memory to maximize throughput in real-world applications.

Furthermore, performance of the BCM can easily be scaled to increase both IPsec and public-key processing performance. The BCM requires no external components or memory and has a power consumption of only 1.

You could want to you could attach a USB drive to your device and mount a local filesystem like ext3 from it. AES support provides latest algorithm support and protects against obsolescence? Notice in this case, that are two drivers offering cbc aes:
