Abstract
Embodiments relate to wrapping of a common cryptographic architecture (CCA) key token. An aspect includes wrapping, by an exporting computer, the CCA key token using a key wrapping export function, the CCA key token comprising a CCA key data section and an unencrypted control vector. Another aspect includes splitting the control vector into a first control vector portion and a second control vector portion. Another aspect includes encrypting the CCA key data section and the first control vector portion using an key encrypting key (KEK) to generate a wrapped key block. Another aspect includes binding the second control vector portion to the wrapped key block to form an associated data section, wherein the associated data section is not encrypted, and wherein the wrapped key block and the associated data section comprise a wrapped key token.
