Скачать или смотреть Apple M chips vulnerable to leak secret encryption Keys

Academic researchers discovered a vulnerability in Apple's M-series chips that allows attackers to extract secret encryption keys during certain cryptographic operations. This flaw is inherent in the chip's design and cannot be directly patched.
Mitigating this vulnerability requires adjustments in third-party cryptographic software, which could significantly degrade the performance of cryptographic operations on M-series chips, especially on the M1 and M2 models.
The flaw exploits the chip's data memory-dependent prefetcher (DMP), which can mistakenly treat secret key material as data addresses, leading to unintended data leaks.
Cryptographic engineers use constant-time programming to prevent timing attacks by ensuring all operations take the same amount of time. The newly discovered vulnerability challenges this approach by leaking data through a side channel.
