A New Type of Cipher: DICING_CSB
Li An-Ping
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.

A new stream cipher: DICING
Li An-Ping
In this paper, we will propose a new synchronous stream cipher named DICING, which can be taken as a clock-controlled one but with a new mechanism of altering steps. With the simple construction, DICING has satisfactory performance, faster than AES about two times. For the security, there have not been found weakness for the known attacks, the key sizes can be 128bits and 256bits respectively.

A NEW MAC: LAMA
Li An-Ping
In this paper, we will propose a MAC with two versions, which is called LAMA. The proposal MAC has the input size of 128 bits and 256 bits in the versions 1, 2 respectively, and output size of 128 bits. There have not been found a attack better than the exhaustive search attack for the MAC, and it has a fast implementations in about 5 cycles/byte in the both versions.

Linear Approximating to Integer Addition
Li An-Ping
The integer addition is often applied in ciphers as a cryptographic means. In this paper we will present some results about the linear approximating for the integer addition.
