P. Hoyer, M. Pei, S. Machani · 2010
This document specifies a symmetric key format for transport and provisioning of symmetric keys to different types of crypto modules. For example One Time Password (OTP) shared secrets or symmetric cryptographic keys to strong authentication devices. The standard key transport format enables enterprises to deploy best-of-breed solutions combining components from different vendors into the same infrastructure.
