A TDGSS Global Quality of Protection (QOP) defines the set of encryption methods and attributes used by the TD2 and LDAP security mechanisms to support confidentiality and integrity.

For Kerberos authentication (KRB5 or SPNEGO mechanisms), the system uses the encryption standard negotiated by Kerberos. See Message Encryption for Kerberos Authentication.

A QOP is based on a TDGSS algorithm, and has some of the same attributes. Algorithm definitions specify all allowable attribute values, whereas an individual QOP contains only one value for each attribute.

The following table describes the attributes present in a QOP.

Attribute Description
Value Global QOP Identifier

Each security mechanism calls out a QOP to define how it performs encryption.

ConfidentialityAlgorithm The algorithm designated by the QOP to perform encryption.
KeyLength The length of the key used for message encryption.
Mode The encryption mode type used by the encryption algorithm.
Padding The encryption padding type used by the encryption algorithm.
IntegrityAlgorithm The algorithm that the QOP designates to maintain message integrity during the encryption/transmission/decryption cycle.
KeyExchangeAlgorithm The algorithm used to perform the encryption key exchange.
KeyLengthP The length of the key used to perform the encryption key exchange
