Data Center Management Systems

• Not reversible to the original production data
  
• Repeatable – Maintains referential integrity between key fields
  
• Customizable
• Specify which characters are changed
  
• Change to similar character types (numbers to numbers, lower-case to lower-case, etc.)
• Supports customizable scramble business rules

• Scrambles sequential files in batch mode
  
• Scrambles sequential backups of VSAM and DB2 data
  
• Processes multiple fields during a single pass of the file
  
• Supports character, packed-decimal and binary field types
  
• Supports fields that are defined as arrays (OCCURS clause)
  
• When file has multiple record formats, provides selection criteria to process specific records
  
• Online facility facilitates selection of scramble fields from COBOL record layout
  
  

• Uses SHA-256 hash of “salt” value to prevent reverse-engineering the original data
  
• Site can choose to encrypt the salt value using DES or AES to prevent others from obtaining the same results
  
• TDS includes utility to create the randomized encryption key using IBM’s ICSF
