iaik.security.cipher.AESCBCCMac192KeyGenerator

public class AESCBCCMac192KeyGenerator
extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating keys to be used with the AESCBCCMac192 authenticated encryption cipher as defined by the BSI Technical Guideline TR-03109-1.

An AES-CBC-CMAC key represents the concatenation of cipher (encryption) key and MAC key (see TR-03109-1): Key = Key_enc||Key_MAC. Thus keys generated by this key generator are 384 bits long: the first 192 bits represent the cipher (encryption) key, the second 192 bits represent the MAC key:

 KeyGenerator keyGen = KeyGenerator.getInstance("AESCBCCMac192");
 SecretKey key = keyGen.generateKey();
