7.116. libica 7.116.1. RHEA-2013:0399 - libica enhancement update Updated libica packages that add one enhancement are now available for Red Hat Enterprise Linux 6. The libica library contains a set of functions and utilities for accessing the IBM eServer Cryptographic Accelerator (ICA) hardware on IBM System z. Enhancement BZ#738835 The libica library has been modified to allow usage of new algorithms that support the Message Security Assist Extension 4 instructions in the Central Processor Assist for Cryptographic Function (CPACF) feature. For the DES and 3DES block ciphers, the new feature supports the following modes of operation: Cipher Block Chaining with Ciphertext Stealing (CBC-CS) Cipher-based Message Authentication Code (CMAC) For the AES block cipher, this feature supports the following modes of operation: Cipher Block Chaining with Ciphertext Stealing (CBC-CS) Counter with Cipher Block Chaining Message Authentication Code (CCM) Galois/Counter (GCM) With this acceleration of complex cryptographic algorithms, performance of IBM System z machines significantly improves. All users of libica are advised to upgrade to these updated packages, which add this enhancement.
