Identity Access Management and Security ,. I've been doing a LOT of writing recently. Unfortunately, or perhaps fortunately depending on how you feel about my writing, it's all been by email to folks inside Oracle and directly with customers. One thing I wrote that is probably interesting for readers of this blog was an answer to a customer's questions about the crypto acceleration capabilities of the Sparc processor.

This is a slight rewrite of that doc The crypto acceleration of Sparc and Solaris when it's used for SSL acceleration is right in the sweet spot of confluence between networking, crypto, performance and architecture. In other words just about my favorite place! Before we get into the technical bits we should probably have a common picture in our heads about what sort of architecture we're talking about. When you deploy web apps you usually have user traffic hit a load balancer which then routes the traffic to your servers.

The simplest diagram of that sort of environment is the three boxes diagram - like so:. I've seen various names for these technologies, so I'm not going to try to assign names to them for the purposes of this post. You might use this model if the load balancer has SSL acceleration technologies either via a hardware card or some software optimization. In the case of 2 and 3 all of the SSL work is handled by the backend server.

Solaris on Sparc offers a few ways to really boost the performance of WebLogic Server. Read on to see what they are. The Sparc processor, especially in its latest revision called the T3, offers some pretty amazing capabilities for crypto operations. The T3 includes 16 cryptographic acceleration engines that support a whole bunch of algorithms including not just AES, but the whole gamut of modern crypto algorithms and constructs.

And it can do those operations at wire speed - which on the Sparc T3 is 10 GbE. To put that another way the Sparc T3 does crypto operations at ludicrous speed. Check out this Wikipedia article and Oracle's web site on the T3 for more info on the processor for more in depth info.

Usually if you wanted to actually take advantage of the crypto acceleration capabilities of the processor your software would need to be specially written to make the necessary calls to the CPU.

There's all sorts of great information out there about these features. A good place to start is this article on the Sun Performance and Best Practices blog. The lowest line on that graph is the "all software" SSL; in other words WebLogic doing the crypto operations in the main CPU without taking advantage of the Sparc's crypto capabilities.

The second line black shows what happens when you start using the crytpo accleration - things go twice as fast. The third line red is even more interesting - it represents enabling a Solaris feature called KSSL and shows that the SSL operations go about three times as fast as the software only implementation; KSSL is a bit more complicated than the normal WebLogic config and so deserves a bit more discussion.

Doing the SSL work inside the kernel saves a bunch system calls shuffling data back and forth between the kernel's memory space and user space so it's faster. As you saw in that graph it can be much faster. The way KSSL is implemented is a lot like the user space stunnel implemented within the kernel, or like what I described in 1 above but inside the OS kernel rather than in another box on the network; either way it's an SSL proxy server.

The application doesn't even need to know that the user is speaking over an SSL channel. If requests that come into your app server are small and don't require much computational effort then KSSL may impart a huge performance boost. If the requests coming into your app server require the app to do a large amount of computation or require the app to talk to a database, SOAP service or something that's slow the performance gain from KSSL might be tiny.

The only way to find out whether it's worth the effort to enable KSSL is to test in your environment with your workload. Once you've load tested and have measured the performance gain you can decide whether you should use KSSL or not.

If you're running WebLogic or indeed any Java application on a Sparc T-series processor you should definitely enable the crypto acceleration capabilities by configuring the PKCS 11 provider. Whether you should use KSSL or not is dependent on your particular environment and uses of the software so you'll need to do some testing to see if it's worth your trouble.

Pwn the ESP32 crypto-core

Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I wanted to use an older T2 machine as a webserver for SSL heavy websites. With Solaris, there is the crypto acceleration available which would make sense for SSL. Now I am wondering if this crypto acceleration has ever been ported to Linux?

Crypto-coprocessors and hardware accelerators for speeding up the RSA encryption and decryption are very popular, but these circuits take the entire algorithm.


There are two methods for crypto hardware acceleration. A newer more native implementation is the CryptoAPI async interface. The latter implementation is still extremely limited. It does not have many drivers yet nor a rich API for userland. It is currently recommended to use OCF for crypto acceleration. Build with modules if you can, especially the cryptosoft driver, as it might otherwise end up taking precedence over your hardware driver. No configuration or recompiling is necessary. Hardware Crypto Acceleration There are two methods for crypto hardware acceleration. Cavium — Octeon Software By using the existing Linux CryptoAPI, the cryptodev software driver provides a fallback mechanism when hardare support is not available. It also allows performance gains on SMP systems and can even help on systems with a small cache or memory all the common crypto code is in one place, and thus smaller and more cache friendly Anything supported by OCF des, 3des, aes, md5, sha1, … can be accelerated via OCF if the hardware supports it.

An approach towards improved cyber security by hardware acceleration of OpenSSL cryptographic functions Abstract: Providing improved Information Security to the rapidly developing Cybernet System has become a vital factor in the present technically networked world. The information security concept becomes a more complicated subject when the more sophisticated system requirements and real time computation speed are considered.

Once enabled 'rand' function will be mapped to HW TRNG; the 'srand' function is not supported, any calls to this function will have no effect.

Boost MCU security AND performance with hardware accelerated crypto

In this guide we will explain how to leverage on Marvell CESA units of the Armada SoC to accelerate network application encryption and disk encryption. Disk encryption acceleration is very straight forward because it's happening in-kernel with kernel subsystem dm-crypt which already supports hardware cryptographic engine. This guide is for advanced users who understand the security implication of tweaking encryption library and cipher configuration. Crypto API is a cryptography framework in the Linux kernel, for various parts of the kernel that deal with cryptography, such as IPsec and dm-crypt. It was introduced in kernel version 2. Many platforms that provide hardware acceleration encryption expose this to programs through an extension of the instruction set architecture ISA of the various chipsets e.

Along with the explosive growth of network data, security is becoming increasingly important for web transactions. These expensive computations through software implementations may not be able to compete with the increasing need for speed and secure connection. Hardly of them presented how to utilize them efficiently. Actually, for some application scenarios, the performance improvement may not be comparable with AES-NI, due to the induced invocation cost for hardware engines. We not only proposed optimal strategies such as data aggregation to advance the contribution with hardware crypto engines, but also presented an Adaptive Crypto System based on Accelerators ACSA with software and hardware codesign. ACSA is able to adopt crypto mode adaptively and dynamically according to the request character and system load. For typical encryption AES supported by instruction acceleration, we could get

The Kinetis Cryptographic Acceleration Unit (CAU) is a primitive accelerator presented as a memory-mapped peripheral. Learn more at SEGGER.


As can be seen in this AES instruction set article, the acceleration is usually achieved by doing certain arithmetic calculation in hardware. Depending on which arithmetic calculations exactly are being done in the specific hardware, the results differ widely. 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!

Crypto Accelerator Cores

Find centralized, trusted content and collaborate around the technologies you use most. Connect and share knowledge within a single location that is structured and easy to search. Does anyone have any idea if these APIs are the ones that are hardware-accelerated or are there other ones? As of 4. The whole point of an API is that you don't need to care about the implementation details that back it. The implementor Apple, in this case will use whatever implementation gives the best performance and energy usage characteristics on whatever hardware is in use.

A crypto-core also called crypto-accelerator is a dedicated piece of hardware inside the System-on-Chip.

Picking the right-sized crypto processor for your SoC

TLS is now deployed as the default for many web-based connections between clients and servers, enabling payment transactions, protecting personal data, and ensuring safe transmission between devices. The TLS protocol is implemented directly on top of the transport layer Figure 1 , enabling application protocols above it e. The TLS protocol provides security for communication across a network by preventing eavesdropping, link tampering, or message forgery using the cryptographic methods of encryption, authentication, and data integrity. Combined, all three methods create a system to support secure communication. For example, modern web browsers are able to authenticate both the client and server, perform message integrity checks for every record, and provide support for a variety of cipher suites. Due to the increase in attacks on the TLS protocol, the standard is evolving to increase the strength of the cryptographic operations required, as well as defining ways to improve the protocol. Because of these increasing cryptographic requirements, increased processor load is the most significant limitation to implementing TLS.
