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.
