Abstract
Methods and apparatus for a secure time service are disclosed. A time server including a time source, a cryptographic key and a cryptographic engine is instantiated within a provider network. A time service endpoint receives a timestamp request from a client. The endpoint transmits a representation of the request to the time server, and receives, from the time server, an encryption of at least a timestamp generated using the time source. A response comprising the encryption of at least the timestamp is transmitted to the requesting client.
