Scalable block ciphers based on Feistel-like structure

Rok, strany: 2002, 39 - 66

Scalability of symmetric ciphers is still not as natural as for public-key cryptosystems. Most of the current block ciphers do not support freely variable block and key lengths, nor do they allow free memory-speed balancing. In this work we discuss possible approaches to a scalable block cipher design and propose a new scalable scheme related to the Feistel structure. We analyze the desirable properties of the used building blocks and present one possible implementation. In addition to a security discussion of the cipher we present some experimental results regarding its statistical properties and efficiency. A nice property of the new cryptosystem is its unlimited scalability and the possibility of a memory-speed tradeoff by a controlled security level.
