WebFeb 27, 2024 · Memory latency was measured at 284-307 cycles. L1 read speeds were measured around 32 bytes per clock (805 GB/s total, ~100 GB/s per core), while write … On processors with the mitigations applied, each affected instruction incurs additional latency and simultaneous execution of RDRAND or RDSEED across cores is effectively serialised. Intel introduced a mechanism to relax these security checks, thus reducing the performance impact in most scenarios, but Intel … See more RDRAND (for "read random"; known as Intel Secure Key Technology, previously known as Bull Mountain ) is an instruction for returning random numbers from an Intel on-chip hardware random number generator which … See more In September 2013, in response to a New York Times article revealing the NSA's effort to weaken encryption, Theodore Ts'o publicly posted concerning the use of RDRAND for /dev/random in the Linux kernel: I am so glad I … See more • AES instruction set • Bullrun (decryption program) • wolfSSL See more The CPUID instruction can be used on both AMD and Intel CPUs to check whether the RDRAND instruction is supported.

WebOct 11, 2024 · 1. While you have described a good way to get a cryptogrically random number, a lot of programs just call a random () function and leave it at that. Depending on the language the implementation could be extremely predictable. For example Delphi (OO Pascal) has a random that's seeded with the time of day. inan harsh prison
