The specification and the reference implementation of PRIMATEs has been updated to v1.1, as a result of a ciphertext forgery by Serge Vaudenay and Damian Vizár. Only HANUMAN is updated; the evaluation of the permutation p1 after the processing of
PRIMATEs has advanced to the second round of the CAESAR competition. We have decided not to tweak PRIMATEs for the second round. The latest version of the specification can be found here: latest specification.
During the Paris Symmetric-Key research retreat, the PRIMATEs team handed over a crate of Westvleteren XII to Brice Minaud. We congratulate Brice Minaud again for winning the Drunkey Monkey Competition, and thank him for sharing his beers during the workshop.
The specification of PRIMATEs has been updated to v1.02. The change with the previous specification, is that we clarify the bounds on collision producing trails (Sect. 4.4.2).
We are happy to announce the winners of the Drunken Monkey Competition. Winner of the crate of Westvleteren XII Trappist beer: Brice Minaud for “Improved Beer-Recovery Attack against APE.” Winner of the 1 kg box of Leonidas chocolates: Phillip Rogaway for
PRIMATEs was be presented by Nicky Mouha at the DIAC 2014 workshop. The DIAC slides are available on-line.
PRIMATEs was presented by Begül Bilgin at the CrossFyre 2014 workshop. The PRIMATEs slides are available on-line.
The specification of PRIMATEs has been updated to v1.01. This specification makes our intention explicit that the nonce length is a fixed-length parameter. We thank Ivan Tjuawinata and Hongjun Wu for their observations regarding variable-length nonces.
PRIMATEs are a family of permutation-based authenticated encryption algorithms for lightweight applications. They are currently under submission to the CAESAR competition. There are three PRIMATEs: the basic SpongeWrap-variant HANUMAN, GIBBON for speed-critical applications, and APE for additional security when nonces
For the most interesting cryptanalysis of PRIMATEs as submitted to first round of the CAESAR competition, we give away an entire crate (24 bottles of 33 cl) of the best beer in the world: the Westvleteren XII Trappist beer. Entries
