The instruction returns a DRBG-generated random number. The DRBG used is considered as secure. The RNDR instruction is available if FEAT_RNG is set. The Juno doesn't support it. When security is enforced (i.e. ENABLE_UNSAFE_RNGLIB is not set), the Juno cannot generate secure random numbers through the RngLib. Secure random numbers could be generated by using the Juno's TRNG. This can be done by: - using the RngDxeLib implementation of the RngLib - RngDxeLib relies on the RngDxe - the RngDxe has access to the TRNG Pierre Gondois (3): Platform/ARM: Place MdeLibs.dsc.inc as the first include Platform/ARM: Move PcdEnforceSecureRngAlgorithms to MdePkg Platform/ARM/Juno: Use DxeRngLib.inf as default RngLib implementation Platform/ARM/JunoPkg/ArmJuno.dsc | 19 +++++++++++++++++-- Platform/ARM/Morello/MorelloPlatformFvp.dsc | 6 +++--- Platform/ARM/N1Sdp/N1SdpPlatform.dsc | 2 +- Platform/ARM/SgiPkg/RdE1Edge/RdE1Edge.dsc | 6 +++--- Platform/ARM/SgiPkg/RdN1Edge/RdN1Edge.dsc | 6 +++--- Platform/ARM/SgiPkg/RdN1EdgeX2/RdN1EdgeX2.dsc | 6 +++--- Platform/ARM/SgiPkg/RdN2/RdN2.dsc | 6 +++--- Platform/ARM/SgiPkg/RdN2Cfg1/RdN2Cfg1.dsc | 6 +++--- Platform/ARM/SgiPkg/RdN2Cfg2/RdN2Cfg2.dsc | 6 +++--- Platform/ARM/SgiPkg/RdN2Cfg3/RdN2Cfg3.dsc | 6 +++--- Platform/ARM/SgiPkg/RdV1/RdV1.dsc | 6 +++--- Platform/ARM/SgiPkg/RdV1Mc/RdV1Mc.dsc | 6 +++--- Platform/ARM/SgiPkg/RdV3/RdV3.dsc | 6 +++--- Platform/ARM/SgiPkg/Sgi575/Sgi575.dsc | 6 +++--- .../VExpressPkg/ArmVExpress-FVP-AArch64.dsc | 2 +- Platform/ARM/VExpressPkg/ArmVExpress.dsc.inc | 2 +- 16 files changed, 56 insertions(+), 41 deletions(-) -- 2.25.1 IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
