  • Data loss prevention with key usage limit enforcement
    Patent number: 10491403
    Abstract: In a distributed system, a computer system responsible, at least in part, for complying with a cryptographic key usage limit for a cryptographic key, obtains results of cryptographic operations generated based at least in part on the cryptographic key and transmits the obtained results over a network. The computer system digitally signs the results and provides the results with digital signatures of the results. Another device intercepts the results and allows the results to proceed to their destination contingent on successful validation of the digital signature.
    Type: Grant
    Filed: January 26, 2018
    Date of Patent: November 26, 2019
    Assignee: Amazon Technologies, Inc.
    Inventors: Marcel Andrew Levy, Darren Ernest Canavor, Zachary Ganwise Fewtrell, Andrew Alphus Kimbrough, Jonathan Kozolchyk, Darin Keith McAdams, Pradeep Ramarao, Gregory Branchek Roth

  • Optimistic key usage with correction
    Patent number: 9853811
    Abstract: Nodes in a distributed system utilize the same cryptographic key, where the cryptographic key is subject to a usage limit. The usage limit is allowed to be temporarily exceeded. When the usage limit is exceeded, results of exceeding the usage limit are corrected to mitigate the effects of exceeding the usage limit.
