Abstract
Communications, such as system event log messages, can be authenticated using a secondary message, as may be sent over a common channel. Each secondary message can be a copy of a corresponding primary message signed with a hash, where that hash can be generated using a secret, such as a secret key. In some embodiments, the secret can be stored in BIOS where the messages are generated, such that an operating system executing on a computing device cannot access the secret in order to send valid secondary messages that match content of the corresponding first messages.
