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.
It is widely used in different markets: wireless telecommunications within SIM cards and embedded SIM, payment within banking cards [2] and NFC mobile payment and for identity cards, healthcare cards, and passports. Several IoT products like gateways are also using Java Card based products to secure communications with a cloud service for instance.
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 oracle returns the bitwise exclusive-or of the key with the string of zeroes. 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 ...
Multi-tier enterprise applications such as Oracle EBS, PeopleSoft, JD Edwards, SAP, Siebel Systems, Business Intelligence, and custom applications built on standard middle-tier servers such as IBM WebSphere and Oracle WebLogic Server mask the identity of end-users at the database transaction level. This is done with an optimization mechanism ...
Encryption takes place within the confines of a security hardened and validated card reading device and data remains encrypted until received by the processing host, an approach pioneered by Heartland Payment Systems [19] as a means to secure payment data from advanced threats, now widely adopted by industry payment processing companies and ...
The attacker can then combine the oracle with a systematic search of the problem space to complete their attack. [1] The padding oracle attack, and compression oracle attacks such as BREACH, are examples of oracle attacks, as was the practice of "crib-dragging" in the cryptanalysis of the Enigma machine. An oracle need not be 100% accurate ...
Network Security Services (NSS) is a collection of cryptographic computer libraries designed to support cross-platform development of security-enabled client and server applications with optional support for hardware TLS/SSL acceleration on the server side and hardware smart cards on the client side.
