  • Patent number: 11829794
    Abstract: A vendor of virtual machine images accesses a virtual computer system service to upload a digitally signed virtual machine image to a data store usable by customers of the virtual computer system service to select an image for creating a virtual machine instance. If a digital certificate is uploaded along with the virtual machine image, the virtual computer system service may determine whether the digital certificate has been trusted for use. If the digital certificate has been trusted for use, the virtual computer system service may use a public cryptographic key to decrypt a hash signature included with the image to obtain a first hash value. The service may additionally apply a hash function to the image itself to obtain a second hash value. If the two hash values match, then the virtual machine image may be deemed to be authentic.

  • Patent number: 11115223
    Abstract: A method and apparatus for distributing cryptographic material are disclosed. In the method and apparatus, cryptographic material is obtained and it is determined that the cryptographic material is to be made available for use by one or more computing resources. The cryptographic material is then sent to one or more secure modules, whereby a secure module of the one or more secure modules is programmatically accessible to a computing resource of the one or more computing resources and programmatic access enables the computing resource to request performance of one or more cryptographic operations using the cryptographic material while exporting the cryptographic material to the computing resource is denied.

  • Patent number: 10460114
    Abstract: Techniques are disclosed for mitigating against registering a domain name that is confusingly similar to a pre-existing domain name, possibly for the purpose of fooling users. In embodiments, a domain name is presented for registration. The domain name is rendered as an image, and optical character recognition is performed on the image to extract the rendered text. This extracted text is compared against a list of domain names for which confusingly similar domain names cannot be registered, and when the extracted text matches a domain name in this list of domain names, registration of the domain name is denied.

  • Patent number: 10362032
    Abstract: Devices, such as hardware security modules, are provided as a service. A customer of a computing resource provider is able to request the addition of a device to a network of the customer hosted by the computing resource provider. The computing resource provider reconfigures a set of computing resources so that the devices of the customer are able to communicate with the device as if the device was in the customer's own network.

  • Patent number: 9552485
    Abstract: A method and apparatus for renewing cryptographic material are disclosed. In the method and apparatus a cryptographic material renewal entity of a computing resource service provider detects that cryptographic material stored by a secure module is to be renewed. Renewing the cryptographic material may include rekeying a private key associated with a certificate. Further, a digital certificate may be renewed, and the renewed certificate may be provided for use by the computing resource. The cryptographic material is used to fulfill requests made by a computing resource provisioned by the computing resource service provider for a customer. The renewed cryptographic material is provided to the secure module, whereby the renewed cryptographic material is used by the secure module to fulfill further requests made by the computing resource.

  • Patent number: 9525672
    Abstract: A compute instance of a virtual computing service (VCS) is assigned first and second cryptographically verifiable identities (CVIs) within respective namespaces. A cryptographic key pair associated with the first CVI includes a non-transferable private key managed by a secure key store which does not permit the private key to be copied. The VCS enables the instance to use the private key for asserting the CVIs. In response to a first identity query, the instance indicates the first CVI. In response to a second identity query, the instance indicates the second CVI.
