Encryption Support Provided by PDM

Encryption Support Provided by PDM
PDM provides the ability to encrypt data transferred between platforms. The discussion
below is an overview of PDM’s encryption capabilities.
E NCRYPTION S TANDAR D U SED - AES 256- BIT
The encryption standard used by PDM is Advanced Encryption Standard (AES). This
standard was established in 2001 by the National Institute of Standards and Technology
(NIST). NIST, an agency of the United States Department of Commerce, adopted this
standard after a five-year study of fifteen competing technologies. AES was fully
adopted by the United States government in 2002 and has since gained widespread
world-wide acceptance.
The AES standard allows the use of three key lengths: 128, 192 and 256 bits keys. PDM
uses 256-bit keys to provide maximum security.
PDM U SAGE
PDM generates separate random 256-bit keys for each encrypted transfer operation.
These keys are never externally stored and reside only within the protected memory of
the PDM tasks.
By default, PDM always encrypts security credentials transferred between systems.
Optionally, users may individually specify that data transfers for selected file transfer
operations also be encrypted. When specified for data transfers, the data is encrypted
on the sending system and de-encrypted on the receiving system before the data is
stored.
U SAGE R ECOMMENDATIONS
Specific usage of PDM encryption is the customer’s choice based on their particular
needs and security requirements. In general, Alebra recommends that customers
encrypt sensitive data that travels over public networks. Encryption, when used with
private networks, is a decision the customer must decide based on their confidence is
their existing network security and security mandates. Alebra does not recommend the
use of PDM encryption for intra-datacenter transfers using z/OpenGate technology due
to the inherent security provided by FICON/Fibre Channel topology and protocols.
