A Canonical Event Log Structure for IMA - David Safford, GE

Sign up or log in to save this to your schedule and see who's attending!

IMA (Integrity Measurement Architecture) provides Linux systems with attestation of runtime components. This presentation will review work in progress to convey attestation information to a verifier in the form of a Canonical Event Log structure. This format will provide cryptographic algorithm agility and sequence numbers. Sequence numbering will enable Event Log list truncation and de-duplication which will optimize storage and transmission. This will allow IMA to bound the size of its internal data structures, including the measurement list and the hash table. This new format will support existing IMA templates while enabling extensible features such as attestation of file metadata. It will also support existing firmware Event Log such as those from UEFI systems. This presentation will demonstrate the current prototype, and discuss integration with an open source verifier.
