The consortium of private companies and academia will focus on ways to protect hardware memory from attacks.

Timing variability of any kind is problematic when working with potentially secret values such as elliptic curve scalars, and such issues can potentially leak private keys and other secrets. Such a problem was recently discovered in `curve25519-dalek`. The `Scalar29::sub` (32-bit) and `Scalar52::sub` (64-bit) functions contained usage of a mask value inside a loop where LLVM saw an opportunity to insert a branch instruction (`jns` on x86) to conditionally bypass this code section when the mask value is set to zero as can be seen in godbolt: - 32-bit (see L106): https://godbolt.org/z/zvaWxzvqv - 64-bit (see L48): https://godbolt.org/z/PczYj7Pda A similar problem was recently discovered in the Kyber reference implementation: https://groups.google.com/a/list.nist.gov/g/pqc-forum/c/hqbtIGFKIpU/m/cnE3pbueBgAJ As discussed on that thread, one portable solution, which is also used in this PR, is to introduce a volatile read as an optimization barrier, which prevents the compiler from op...
