A New Type of Cipher: DICING_CSB

Li An-Ping

Abstract: In this paper, we will propose a new type of cipher named DICING_CSB, which come from our previous a synchronous stream cipher DICING. It applies a stream of subkeys and a encryption form of block ciphers, so, it can be viewed a combinative of stream cipher and block cipher. Hence, the new type of cipher has fast speed like a stream cipher and no need MAC.

Category / Keywords: secret-key cryptography / stream cipher, block cipher,finite field.
