Elastic block ciphers

Debra L. Cook, Angelos D. Keromytis, Moti M. Yung

Abstract

We introduce the concept of an elastic block cipher, which refers to stretching the supported block size of a block cipher to any length up to twice the original block size while incurring a computational workload that is proportional to the block size. We define a method for converting any existing block cipher into an elastic block cipher and mention our analysis of the construction.
