Enhanced Secure Comparison Schemes Using Homomorphic Encryption
Comparing two integers under the encrypted form is useful for privacy-preserving data mining, secure auction, and so on. Based on the ring-learning with errors (ring-LWE) assumption, Saha and Koshiba proposed ...

Can We Securely Use CBC Mode in TLS1.0?
Currently, TLS1.0 is one of the most widely deployed protocol versions for SSL/TLS. In TLS1.0, there are only two choices for the bulk encryption, i.e., RC4 or block ciphers in the CBC mode, which have been cr...

Differential and Impossible Differential Related-Key Attacks on Hierocrypt-L1
Hierocrypt-L1 is one of the Japanese e-Government Recommended Ciphers listed by CRYPTREC in 2003, and its security was reconfirmed as secure by CRYPTREC in 2013. In this paper we first find differential charac...

The 128-Bit Blockcipher CLEFIA (Extended Abstract)
We propose a new 128-bit blockcipher CLEFIA supporting key lengths of 128, 192 and 256 bits, which is compatible with AES. CLEFIA achieves enough immunity against known attacks and flexibility for efficient im...

Impossible Differential Cryptanalysis of Zodiac
We discuss the impossible differential cryptanalysis of the block cipher Zodiac [7]. The main design principles of Zodiac are simplicity and efficiency. However the diffusion layer in its round function is too si...

Efficient Algorithms for Computing Differential Properties of Addition
In this paper we systematically study the differential properties of addition modulo 2n. We derive Θ(logn)-time algorithms for most of the properties, including differential probability of addition. We also prese...

Camellia: A 128-Bit Block Cipher Suitable for Multiple Platforms — Design andAnalysis
We present a new 128-bit block cipher called Camellia. Camellia supports 128-bit block size and 128-, 192-, and 256-bit keys, i.e., the same interface specifications as the Advanced Encryption Standard (AES). Eff...

On the Pseudorandomness of Top-Level Schemes of Block Ciphers
Block ciphers are usually basedon one top-level scheme into which we plug “roundf unctions”. To analyze security, it is important to study the intrinsic security provided by the top-level scheme from the viewp...
