Java

Design and implementation of recipient anonymity on the client side of AN.ON. Includes the design of a new key agreement protocol, with inspiration taken from TOR’s key agreement protocol. Uses a custom version of the Bouncy Castle crypto library. Encryption is done via AES-128 CTR, signatures are beeing generated via Ed25519 and Curve25519 is used as the underlying key agreement mechanism.

A Java-based tool to create Braille embosser text files for generic diagram representations, which then can be printed on an Braille embosser. To ensure extensibility and variability of the Software, the architecture was designed with these corresponding patterns in mind, so that generic Braille printers and embossers can be used interchangably. A visualization tool (also in Java) was created so that the user has a preview option of the Braille text which will be printed.

Project collaboration on a Java and C++ based simulator for interplanetary internet, which includes the bundle protocol for Delay Tolerant Networking.
