Oracle Advanced Security, an extra-cost option for Oracle database environments, extends Oracle Net Services in the field of database computing to provide network security, enterprise-user security, public-key infrastructure security [1] and data encryption to users of Oracle databases.
Oracle Advanced Security TDE column encryption was introduced in Oracle Database 10g Release 2. Oracle Advanced Security TDE tablespace encryption and support for hardware security modules (HSMs) were introduced with Oracle Database 11gR1. Keys for TDE can be stored in an HSM to manage keys across servers, protect keys with hardware, and ...
Encryption can be employed to enhance the security of data stored in a database by converting the information into an unreadable format using an algorithm. The encrypted data can only be accessed and deciphered with a decryption key, ensuring that even if the database is compromised, the information remains confidential.
The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), [5] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. [6]
In cryptography, a padding oracle attack is an attack which uses the padding validation of a cryptographic message to decrypt the ciphertext. In cryptography, variable-length plaintext messages often have to be padded (expanded) to be compatible with the underlying cryptographic primitive .
The string returned by the oracle is the secret key. While the one-time pad is used as an example of an information-theoretically secure cryptosystem, this security only holds under security definitions weaker than CPA security. This is because under the formal definition of CPA security the encryption oracle has no state.
SocialDocs file encryption uses AES256 to provide a free-online file encryption tool XFire uses AES-128, AES-192 and AES 256 to encrypt usernames and passwords Certain games and engines, such as the Rockstar Advanced Game Engine used in Grand Theft Auto IV , use AES to encrypt game assets in order to deter hacking in multiplayer.
