Specify a B2B Tape Using a Code Book

Specify the code book name and the algorithm to use for encryption.

The syntax for the character string value has the following format:

BESn=(BOOK(codebook_name).algorithm)

n

Specifies an identifying number for a CA Tape Encryption subsystem other than BES1.

BOOK(codebook_name)

Specifies that a B2B tape uses the code book methodology for selecting and communicating a symmetric key. The codebook_name in parenthesis specifies the value specified by the CodeBook attribute of the <B2BCodeBooks> section, which also names the related customizable section in PARMLIB.

algorithm

Specifies the algorithm for creating the randomly-generated symmetric key that is used to encrypt the data on the tape.

Example: Specify a code book

In this example, BES2=(BOOK(CodeBook1).AES192) indicates that this tape uses the code book identified as CodeBook1 to generate the symmetric key that is used to encrypt the data on the tape. AES192 indicates the encryption algorithm to use for the symmetric key that encrypts the data on the tape. BES2 indicates that this is a tape for subsystem BES2.
