Cryptography

Today’s world mandates that your systems are secure and available 24/7. The z10 EC employs some of the most advanced security technologies in the industry—helping you to meet rigid regulatory requirements that include encryption solutions, access control management, and extensive auditing features. It also provides disaster recov- ery confi gurations and is designed to deliver 99.999% application availability to help avoid the downside of planned downtime, equipment failure, or the complete loss of a data center.

When you need to be more secure, more resilient —

z Can Do IT. The z10 processor chip has on board cryp- tographic functions. Standard clear key integrated crypto- graphic coprocessors provide high speed cryptography for protecting data in storage. CP Assist for Cryptographic Function (CPACF) supports DES, TDES, Secure Hash Algorithms (SHA) for up to 512 bits, Advanced Encryption Standard (AES) for up to 256 bits and Pseudo Random Number Generation (PRNG). Logging has been added to the TKE workstation to enable better problem tracking.

System z is investing in accelerators that provide improved performance for specialized functions. The Crypto Express2 feature for cryptography is an example. The Crypto Express2 feature can be confi gured as a secure key coprocessor or for Secure Sockets Layer (SSL) accel- eration. The feature includes support for 13, 14, 15, 16, 17, 18 and 19 digit Personal Account Numbers for stronger protection of data. And the tamper-resistant cryptographic coprocessor is certifi ed at FIPS 140-2 Level 4.

In 2008, the z10 EC received Common Criteria Evalua- tion Assurance Level 5 (EAL5) certifi cation for security of logical partitions. System z security is one of the many reasons why the world’s top banks and retailers rely on the IBM mainframe to help secure sensitive business transac- tions.

z Can Do IT securely.

The z10 EC includes both standard cryptographic hard- ware and optional cryptographic features for fl exibility and growth capability. IBM has a long history of providing hard- ware cryptographic solutions, from the development of Data Encryption Standard (DES) in the 1970s to delivering integrated cryptographic hardware in a server to achieve the US Government’s highest FIPS 140-2 Level 4 rating for secure cryptographic hardware.

The IBM System z10 EC cryptographic functions include the full range of cryptographic operations needed for e- business, e-commerce, and fi nancial institution applica- tions. In addition, custom cryptographic functions can be added to the set of functions that the z10 EC offers.

New integrated clear key encryption security features on z10 EC include support for a higher advanced encryption standard and more secure hashing algorithms. Performing these functions in hardware is designed to contribute to improved performance.

Enhancements to eliminate preplanning in the cryptogra- phy area include the System z10 function to dynamically add Crypto to a logical partition. Changes to image pro-

les, to support Crypto Express2 features, are available without an outage to the logical partition. Crypto Express2 features can also be dynamically deleted or moved.

CP Assist for Cryptographic Function (CPACF)

CPACF supports clear-key encryption. All CPACF func- tions can be invoked by problem state instructions defi ned by an extension of System z architecture. The function is activated using a no-charge enablement feature and offers the following on every CPACF that is shared between two Processor Units (PUs) and designated as CPs and/or Inte- grated Facility for Linux (IFL):

DES, TDES, AES-128, AES-192, AES-256

SHA-1, SHA-224, SHA-256, SHA-384, SHA-512

Pseudo Random Number Generation (PRNG)
