11.22. BATON mechanisms

11.22.1. BATON key generation


The BATON key generation mechanism, denoted CKM_BATON_KEY_GEN, is a key generation mechanism for BATON. The output of this mechanism is called a Message Encryption Key (MEK).
It does not have a parameter.
This mechanism contributes the CKA_CLASS, CKA_KEY_TYPE, and CKA_VALUE attributes to the new key.

11.22.2. BATON-ECB128


BATON-ECB128, denoted CKM_BATON_ECB128, is a mechanism for single- and multiple-part encryption and decryption with BATON in 128-bit electronic codebook mode.
It has a parameter, a 24-byte initialization vector. During an encryption operation, this IV is set to some value generated by the token—in other words, the application cannot specify a particular IV when encrypting. It can, of course, specify a particular IV when decrypting.
Constraints on key types and the length of data are summarized in the following table:
