As of 2026, local mixing has not yet sufficiently eliminated correlations between original circuit values and their obfuscated counterparts. 21 Aug
A sufficiently large random reversible circuit is plausibly a secure cryptographic permutation, while a large random irreversible circuit collapses to only a few possible outputs. 21 Aug
Local mixing, a new cryptographic obfuscation approach, is a risky bet resembling past failed attempts at white-box cryptography. 21 Aug
