database access descriptor
A database access descriptor (DAD) is a set of values that specify how an
application connects to an Oracle database to fulfill an HTTP request. The
information in the DAD includes the username (which also specifies the schema
and the privileges), password, connect-string, error log file, standard error message,
and national language support (Globalization Support) parameters such as
Globalization Support language.
decryption
The process of converting the contents of an encrypted message ( ciphertext ) back
into its original readable format ( plaintext ).
DES
Data Encryption Standard. A commonly used symmetric key encryption method
that uses a 56-bit key.
Diffie-Hellman key negotiation algorithm
Diffie-Hellman key negotiation algorithm is a method that lets two parties
communicating over an insecure channel to agree upon a random number known
only to them. Though the parties exchange information over the insecure channel
during execution of the Diffie-Hellman key negotiation algorithm, it is
computationally infeasible for an attacker to deduce the random number they agree
upon by analyzing their network communications. Oracle Advanced Security uses
the Diffie-Hellman key negotiation algorithm to generate session keys.

directory information tree
