Very Compact Hardware Implementations of the Blockcipher CLEFIA
نویسندگان
چکیده
The 128-bit blockcipher CLEFIA is known to be highly efficient in hardware implementations. This paper proposes very compact hardware implementations of CLEFIA-128. Our implementations are based on novel serialized architectures in the data processing block. Three types of hardware architectures are implemented and synthesized using a 0.13 μm standard cell library. In the smallest implementation, the area requirements are only 2,488 GE, which are about half of the previous smallest implementation as far as we know. Furthermore, only additional 116 GE enable to support decryption.

The 128-Bit Blockcipher CLEFIA
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 implementation in both hardware and software by adopting several novel and state-of-the-art design techniques. CLEFIA achieves a good performance profile both in hardware and software. In ha...
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 کاملA Practical Chosen Message Power Analysis Method on the Feistel-SP ciphers with Applications to CLEFIA and Camellia
The Feistel-SP structure is a commonly adopted structure in symmetric cryptography with many practical instances. Differential power analysis (DPA) has proven to be effective against these ciphers with compact implementations within these years. However, the applications of DPA on Feistel-SP ciphers with loop hardware implementations are more complicated and less evaluated in literature, mainly...
متن کاملDual CLEFIA/AES Cipher Core on FPGA
In this paper a compact high throughput dual-cipher hardware structure is proposed, supporting the novel CLEFIA algorithm and the encryption standard AES. Currently, the more efficient and dedicated structures only allow to process the CLEFIA or the AES encryption algorithms. On the other hand, the existing multi-algorithm processors impose significantly higher area costs and are not able to ac...
