Oracle Advanced Security provides industry standards-based data privacy, integrity, authentication, single sign-on, and access authorization in a variety of ways. Sensitive information that is stored in your database or that travels over enterprise networks and the Internet can be protected by encryption algorithms. An encryption algorithm transforms information into a form that cannot be deciphered without a decryption key. Oracle Advanced Security supports multiple industry standard encryption algorithms such as RC4, DES3 and Triple-DES. To ensure the integrity of data packets during transmission, Oracle Advanced 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.
