A New Type of Cipher: DICING_csb

TL;DR

This paper introduces DICING_csb, a novel cipher combining stream and block cipher features, offering high speed without requiring a MAC, based on previous work DICING.

Contribution

It presents a new cipher design that integrates stream and block cipher elements, expanding the cryptographic landscape.

Findings

Fast encryption rate comparable to stream ciphers

No need for MAC in the encryption process

Derived from the previous DICING cipher

Abstract

In this paper, we will propose a new type of cipher named DICING_csb, which is derived from our previous stream cipher DICING. It has applied a stream of subkey and an encryption form of block ciphers, so it may be viewed as a combinative of stream cipher and block cipher. Hence, the new type of cipher has fast rate like a stream cipher and need no MAC.
