- Dragon (cipher)
-
Dragon is a stream cipher developed at the Information Security Institute by Ed Dawson, Kevin Chen, Matt Henricksen, William Millan, Leonie Simpson, HoonJae Lee, and SangJae Moon.
The cipher is a Phase 3 Focus candidate for the eSTREAM project. The cipher is targeted for fast software implementations and versions with different key lengths exists. The version selected for Phase 3 is Dragon-128. It is not patented.
Dragon has not been successfully attacked to date, but Cho and Pieprzyk found biases within the primary non-linear component of the cipher[1]. This suggests that the security of the cipher is weaker than intended by its designers.
