Synopsis

libica enhancement update

Type/Severity

Product Enhancement Advisory

Topic

Updated libica packages that add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The libica library contains a set of functions and utilities for accessing the IBM eServer Cryptographic Accelerator (ICA) hardware on IBM System z.

This update adds the following enhancement:

  • 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. (BZ#738835)

All users of libica are advised to upgrade to these updated packages, which add this enhancement.
