The quality of protection (QOP) defines the strength of the encryption algorithms the system uses when transmitting messages between Teradata Database and its clients.
There are 2 types of policy subject to Quality of Protection (QOP):
- An integrity QOP determines the strength of the algorithm the system uses for calculating the checksum that guarantees message integrity.
- A confidentiality QOP determines the strength of the algorithm for encrypting a message exchange between a client and Teradata Database. In the absence of a confidentiality QOP policy, client requests for confidentiality use the DEFAULT QOP. See Encryption.
You can assign confidentiality and integrity policies by:
- Database user name or directory user name
- Database profile
- Client IP address
You can also enforce use of the DEFAULT confidentiality QOP by host group ID. See Requiring Confidentiality.
