Patent number: 11960608Abstract: A method to secure boot an electronic device is disclosed according to some embodiments. The method includes receiving a request to initiate a boot sequence using memory content stored in a non-volatile memory circuit. A secure boot circuit receives verification data from the non-volatile memory circuit indicating the memory content. The verification data includes an error correction code for the memory content without including all of the memory content. A cryptographic hashing operation is performed to the error correction code in the secure boot circuit to obtain a digest of the error correction code. The digest is compared with a pre-stored reference digest to generate a verification signal. The verification signal is provided to the electronic device indicating whether the boot sequence passes the verification.Type: GrantFiled: April 29, 2021Date of Patent: April 16, 2024Assignee: Infineon Technologies AGInventors: Atilla Bulmus, Jeffrey Todd Kelley, Chris Wunderlich

Patent number: 10990590Abstract: Database systems and methods that implement a data aggregation framework are provided. The framework can be configured to optimize aggregate operations over non-relational distributed databases, including, for example, data access, data retrieval, data writes, indexing, etc. Various embodiments are configured to aggregate multiple operations and/or commands, where the results (e.g., database documents and computations) captured from the distributed database are transformed as they pass through an aggregation operation. The aggregation operation can be defined as a pipeline which enables the results from a first operation to be redirected into the input of a subsequent operation, which output can be redirected into further subsequent operations. Computations may also be executed at each stage of the pipeline, where each result at each stage can be evaluated by the computation to return a result. Execution of the pipeline can be optimized based on data dependencies and re-ordering of the pipeline operations.Type: GrantFiled: September 15, 2017Date of Patent: April 27, 2021Assignee: MongoDB, Inc.Inventors: Dwight Merriman, Eliot Horowitz, Chris Todd Westin
