Lapin: An Efficient Authentication Protocol Based on Ring-LPN

WitrynaPerformance-wise, our protocol is more efficient than previous LPN-based schemes, such as the many variants of the Hopper-Blum (HB) protocol and the aforementioned protocol from Eurocrypt’11. Our implementation results show that it is even comparable to the standard challenge-and-response protocols based on the AES block-cipher.

WitrynaAn Algorithmic Framework for the Generalized Birthday Problem Itai Dinur Department of Computer Science, Ben-Gurion University, Israel Abstract. The generalized … The new attack combines linearization and generalized birthday attacks and thus, is faster than all these attacks. Furthermore, both algorithms are slightly improved. This leads to practical attacks against the cryptosystems. The algorithm was implemented and allowed to nd a collision in FSB-48 in far less ressources than previously in [3].
