A mode of operation for block ciphers enhances the standard XTS-AES mode of operation to perform memory encryption by extending a tweak to include a “time stamp” indicator. An incrementing mechanism using the “time stamp” indicator generates a tweak which separates different contexts over different times such that the effect of “Type 2 replay attacks” is mitigated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tweakable encryption mode for memory encryption with protection against replay attacks","description":"A method and apparatus for protecting against hardware attacks on system memory is provided.
