Differential Cache Trace Attack Against CLEFIA
نویسندگان
چکیده
The paper presents a differential cache trace attack against CLEFIA, a 128 bit block cipher designed by Sony Corporation. The attack shows that such ciphers based on the generalized Feistel structures leak information of the secret key if the cache trace pattern is revealed to an adversary. The attack that we propose is a three staged attack and reveals the entire key with 2 CLEFIA encryptions. The attack is simulated on an Intel Core 2 Duo Processor with a cache architecture with 32 byte lines as a target platform.

An Enhanced Differential Cache Attack on CLEFIA for Large Cache Lines
Reported results on cache trace attacks on CLEFIA do not work with increased cache line size. In this paper we present an enhanced cache trace attack on CLEFIA using the differential property of the s-boxes of the cipher and the diffusion properties of the linear transformations of the underlying Feistel structures. The attack requires 3 round keys, which are obtained by monitoring cache access...
متن کاملImproved Cache Trace Attack on AES and CLEFIA by Considering Cache Miss and S-box Misalignment
This paper presents an improved Cache trace attack on AES and CLEFIA by considering Cache miss trace information and S-box misalignment. In 2006, O. Acıiçmez et al. present a trace driven Cache attack on AES first two rounds, and point out that if the Cache element number of the Cache block is 16, at most 48-bit of AES key can be obtained in the first round attack. Their attack is based on the ...
متن کاملProtecting Last Four Rounds of CLEFIA is Not Enough Against Differential Fault Analysis
In this paper we propose a new differential fault analysis (DFA) on CLEFIA of 128-bit key. The proposed attack requires to induce byte faults at the fourteenth round of CLEFIA encryption. The attack uses only two pairs of fault-free and faulty ciphertexts and uniquely determines the 128-bit secret key. The attacker does not need to know the plaintext. The most efficient reported fault attack on...
متن کاملCompact and High Speed Hardware Implementation of the Block- Cipher Clefia
Main fundamental directions which are considered as important for practical ciphers are (1) security, (2) speed, and (3) cost for implementations. To realize these fundamental directions CLEFIA is designed. Clefia is a first block cipher employing the Diffusion Switching Mechanism (DSM) to enhance the immunity against the differential attack and the linear attack. Clefia uses lightweight compon...
متن کاملImpossible Differential-Linear Cryptanalysis of Reduced-Round CLEFIA-128
CLEFIA is a 128-bit block cipher proposed by Sony Corporation in 2007. Our paper introduces a new chosen text attack, impossible differential-linear attack, on iterated cryptosystems. The attack is efficient for 16-round CLEFIA with whitening keys. In the paper, we construct a 13-round impossible differential-linear distinguisher. Based on the distinguisher, we present an effective attack on 16...
