Unlike the RDRAND instruction, the seed values come directly from the entropy conditioner, and it is possible for callers to invoke RDSEED faster than those values are generated. This means that applications must be designed robustly and be prepared for calls to RDSEED to fail because seeds are not
3 Dec 2016 If I were designing a mass produced TRNG in the US I'd produce a very convincing diagram filled with technobabble. Then I'd create a RDRAND instruction that just calls a simple XOR shift generator. If you're headquartered in the US, it might be this approach or jail time for supporting /facilitating terrorism, especially if an
RDRAND is an instruction for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source. RDRAND is available in Ivy Bridge processors and is part of the Intel 64 and IA-32 instruction set architectures. AMD added support for the instruction in
18 Dec 2016 Is the system clock not enough for a seed? How about a hardware generated seed? Modern x86-based processors are equipped with power tools, such as the RDSEED instruction. It's rather a bit overkill to use in simple applications, but if you need a NIST SP800-90B and C compliant random value then
29 Nov 2017 RDSEED is a similar class for access to the rdseed instruction. The classes GCC ASM and MASM/MASM64 assembly language routines are provided to ensure the library can call the instruction if its available. Intel's RDRAND is designed to never underflow, but its not clear what AMD's behavior is.
6 Mar 2016 But I think this is rather less likely, and the RNG used in Botan should be safe even if it were (in that it is designed to accept seed inputs even from such an Processors that do not support the RDSEED instruction can leverage the reseeding guarantee of the DRBG to generate random seeds from values
17 Nov 2012 Intel recently announced the addition of the RDSEED instruction to the Intel® 64 and IA-32 Architectures. An addition to Intel® Secure Key, this new instruction will appear in future generations of Intel processors. Like RDRAND the RDSEED instruction returns random numbers, and with two instructions that
12 Nov 2015 RDRAND and RDSEED are not a part of any specific ISA extension set. They are their own set and have their own specific bits allocated in the CPUID instruction. They were developed under the "Bull Mountain" codename and are today marketed as Intel Secure Key. Intel Secure Key was added in
1 Aug 2016 Thus intel designed the instruction to return an “error" using the carry flag if insufficient time has passed since the last call of RDSEED. So the basic idea is that an attacker could create a covert channel using this instruction. To send a 1 bit the sender implant loops an rdseed instruction and mean while the
