Communication support modules for data transmission encryption

You can use the communication support modules (CSMs) to encrypt data transmissions, including distributed queries, over the network.

The encryption CSM (ENCCSM) provides network transmission encryption.

This option provides complete data encryption with a standard cryptography library, with many configurable options. A message authentication code (MAC) is transmitted as part of the encrypted data transmission to ensure data integrity. A MAC is an encrypted message digest.

CSMs have the following restrictions:

Secure Sockets Layer (SSL) communications, which encrypt data in end-to-end, secure TCP/IP and Distributed Relational Database Architecture™ (DRDA) connections between two points over a network, are an alternative to the HCL Informix®-specific encryption CSMs. For more information, see Secure sockets layer protocol.
