197, Advanced Encryption Standard (AES) is a new cryptographic algorithm
standard developed to replace DES. AES is a symmetric block cipher that can
process data blocks of 128 bits, using cipher keys with lengths of 128, 192, and 256
bits, which are referred to as AES-128, AES-192, and AES-256, respectively. All three
versions operate in outer-CBC mode.

Data Integrity
To ensure the integrity
Security can generate a cryptographically secure message digest—using MD5 or
SHA-1 hashing algorithms—and include it with each message sent across a
network.
Data integrity algorithms add little overhead, and protect against the following
attacks:
Data modification
Deleted packets
Replay attacks
SHA-1 is slightly slower than MD5, but produces a larger

message digest, making it more secure against brute-force collision
and inversion attacks.

Federal Information Processing Standard
Oracle Advanced Security Release 8.1.6 has been validated under U.S. Federal
Information Processing Standard 140-1 (FIPS) at the Level 2 security level. This
provides independent confirmation that Oracle Advanced Security conforms to
federal government standards. FIPS configuration settings are described by
