简单来说:RDRAND适用三代以后的Intel处理器及2015年以后的AMD处理器RDSEED适用五代以后Intel处理器及AMD Zen架构以后的处理器判断方法CPUID.01H:ECX.RDRAND[bit 30] = 1CPUID.(EAX=07H, ECX=0H):EBX.RDSEED[bit 18] = 1我重新整理并把RdSeed指令和CPU是否支持RdRand/RdSeed指令的判断程序写全了可以说比较...
rdrand指令是Intel引入的一种硬件随机数生成指令,但它也可以在AMD处理器上使用。该指令通过硬件随机数生成器生成真随机数,具有高度的安全性和可靠性。在AMD FX 8350处理器上,rdrand指令可以用于各种需要随机数的场景,如密码学、安全通信、模拟和仿真等。 腾讯云提供了丰富的云计算产品和服务,其中包括适用于各种应用场景...
Allan_J_Intel1 Employee 03-20-2014 09:34 AM 709 Views Thanks for joining the community. If you are software developer, I would highly recommend you engage the software developer forum for issues with rdrand. There is a lot of expertise in the community for working with issues like...
No mitigation is done to modify the output of the hardware to prevent problems with Intel's implementation. Caveat Emptor.RdSeedom is a subclass of random.Random, and behaves like random.Random, but it uses inline assembly to access the hardware RNG using the RdSeed instruction. This should ...
I'm looking to consume Intel's Digital Random Number Generator (the RDRAND instruction in Ivy Bridge) from a C# assembly. I've looked at cpp libs but I was hoping there was a more "managed" solution. Any ideas? c# random cryptography intel rdrand Share Improve this question Follow ...
in 是把外表和内表做 hash 连接，而 exists 是对外表作 loop 循环，每次 loop 循环再对内表进行查询...
[0] He's the main developer behind Linux's RNG and staunchly resisted relying only on Intel's RDRAND. His opinions carry weight with good reason. [1] https://lwn.net/Articles/586427/ It may be that there is some very complex state which is hidden inside the the CPU execution ...
