Could you build this?

No Writing a mathematically constant-time cryptographic implementation of AES requiring 80ns S-box computations without data-dependent branching or memory lookup tables demands deep cryptographic engineering expertise and assembly/low-level hardware verification.

What it would actually take: A real implementation requires Galois field GF(2^8) arithmetic via bit-slicing or tower-field decomposition (such as Canright's algorithm) implemented in C, Rust, or assembly. The core challenge is guaranteeing constant-time execution across hardware architectures to eliminate cache-timing and microarchitectural side-channels, requiring formal verification with tools like dudect or valgrind-based taint analysis. This necessitates a senior cryptographic engineer with microarchitectural and timing-attack expertise.
