Elastic block ciphers: the basic design

Download www.cs.columbia.edu

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. Categories and Subject Descriptors E.0 [General]: Data Encryption General Terms block ciphers, algorithms, encryption Keywords variable-length block ciphers, elastic block ciphers
