We publish this work as responsible disclosure. While a full SHA-256 collision (sr = 64) has not yet been achieved, the tools and techniques presented here represent significant methodological advances that bring it closer. Organizations relying on SHA-256 for collision resistance should begin evaluating migration paths to SHA-3 or other post-quantum hash functions. The cryptographic community should treat the collision resistance of SHA-256 as having a finite and shrinking safety margin.
It looks like there is a core cord inside the zipper teeth. The specialized sewing machine stitches the cord to the fabric in between each teeth... tooth?
> Through the years, imec has made considerable progress in assessing, understanding, and modeling reliability failure, paving the way to building reliable IGZO transistors with a target lifetime of five years
Replacing your DRAM sticks every five years may be okay, but what about for boards with soldered on memory?
