The ZTRUST working group exists to educate and inform members of the Z (mainframe) community about cryptographic trust issues, starting with code signing.
The working group also exists to provide a "trust anchor" which can be used for verifying delivered code ("artifacts") and related content.
- Education/Information
As of this writing, many members of the Z community remain unfamiliar with trust anchors, cryptographic signing, PKI and PGP, and related topics. This working group will fill the gaps.
- Trust Anchor
While many trust anchors, trust paths, and trust chains already exist, it seemed helpful to establish a community trust anchor for those software deliverables and related services which fall outside of established and commercial trust space.
