  • Publication number: 20250119286
    Abstract: A system for homomorphically generating rotation keys for use in homomorphic computation in association with a client, and a server coupled to the client machine over a network. Client-side code executes in the client to derive a set of Learning With Errors (LWE) ciphertexts from a secret key polynomial, the secret key polynomial having a set of coefficients. Each LWE ciphertext is derived from a coefficient of the secret key polynomial and having a single coefficient. The client-side code transmits the set of LWE ciphertexts to the server. Server-side code receives the set of LWE ciphertexts and processes them into a ring variant (R-LWE) ciphertext homomorphically to generate the one or more rotation keys. The R-LWE ciphertext encrypts a polynomial having the set of coefficients of the secret key polynomial; a given rotation key corresponds to rotated coefficients of that polynomial. The generated rotation keys are useful for FHE computation.

  • Publication number: 20250117296
    Abstract: An embodiment maps identifying information of a remote registry into a database within a local inventory at a local registry hub. An embodiment selects at least one remote registry from an index maintained in the local inventory in accordance with a policy received at a scheduler from an external client of the local registry hub. An embodiment selects a locally stored image in accordance with a policy received from an external client of the local registry hub. An embodiment uploads replicas of the selected image via one or more registry agents, each registry agent transmitting to its corresponding remote registry, transmitting constituent layers of the replica across multiple remote registries simultaneously such that a subset of the layers constituting the image are uploaded to each remote registry. An embodiment stores metadata for the uploaded image in a cache within a local metadata store.

  • Patent number: 12273451
    Abstract: Device-implemented methodology for enabling and/or performing crypto-erase via internal action and/or external action in a Key per IO-enabled system. In various approaches, crypto-erasure of the data stored in a Key per IO scheme is enabled by implementing an internal key, which is combined with an external key to generate a media encryption key, which is in turn used to encrypt/decrypt data. By restricting access to the internal key, destruction of the internal key and all media encryption key(s) created using the internal key, renders the data crypto-erased, and thus unrecoverable.

  • Patent number: 12270848
    Abstract: A signal-analysis-based process for detecting and correcting power feeds is provided. The process includes obtaining voltage waveform data for power feeds connected to a system, and determining for the power feeds, using the obtained voltage waveform data, at least one respective signal characteristic. Further, the process includes comparing the respective signal characteristics of the power feeds to ascertain at least one signal characteristic difference between the power feeds. Based on the at least one signal characteristic difference not exceeding at least one respective difference limit, the process determines that the power feeds are not separately-sourced redundant power feeds connected to the system, and based on determining that the power feeds are not separately-sourced redundant power feeds, the process initiates a corrective action to ensure that the system is connected to separately-sourced redundant power feeds.

  • Patent number: 12271469
    Abstract: A method, system, and computer program product implement a three-factor authorization in a trusted computing environment. The method includes triggering, by a hypervisor, a start of a secure guest by passing control regarding an image of the secure guest and metadata of the secure guest to a trusted firmware, where the secure guest is designed to access a hardware security module (HSM). Upon a successful integrity check of the metadata of the secure guest by the trusted firmware, the secure guest is started using the hypervisor and any sensitive request from the secure guest to the HSM is blocked. The secure guest submits a request with a request structure including a third authorization secret and a characterization of a requested HSM to the trusted firmware. The method also includes binding each HSM protected key generated in the requested HSM in response to the request to the third authorization secret.
