Κ-Cipher: A Low Latency, Bit Length Parameterizable Cipher

Michael Kounavis and Sergej Deutsch and Santosh Ghosh and David Durham

Abstract: We present the design of a novel low latency, bit length parameterizable cipher, called the K-Cipher''. K-Cipher is particularly useful to applications that need to support ultra low latency encryption at arbitrary ciphertext lengths. We can think of a range of networking, gaming and computing applications that may require encrypting data at unusual block lengths for many different reasons, such as to make space for other unencrypted state values. Furthermore, in modern applications, encryption is typically required to complete inside stringent time frames in order not to affect performance. K-Cipher has been designed to meet these requirements. In the paper we present the K-Cipher design and discuss its rationale.
