Revelation of Underlying Feistel Structure in Stream Ciphers
Gongliang Chen · Information Security and Communications Privacy · 2009
In this paper, we reveal a restructuring method which might change the explicit complex structures or partof the structures in the algorithm into the framework of Feistel. By this method, we can change several algorithms inthe Program of eStream into Feistel Structure, and we hope this will reveal new attacking method for the cryptanalysis.
