|Title||Examining Authenticated Encryption Proposals|
|Presenter||Leonie Simpson (Queensland University of Technology)|
|Session||Cryptography, Coding and Compression|
This research examines cryptographic methods for securing communications between small devices. The transmission of data between devices is often over untrusted wireless or public networks, which gives rise to security concerns: the transmitted data may be exposed to the actions of other entities. Cryptographic algorithms can be used to provide confidentiality for a transmission and also an authenticator; enabling the recipient to detect modifications to the transmission. Simultaneously performing both encryption for confidentiality and computing a message authentication code to provide integrity assurance is known as authenticated encryption (AE). This has potential to provide these two security services more efficiently than providing them independently. However, flaws exist in some current AE proposals.
