“…Our result enables us to build a secure GFS cipher having a fewer rounds than Type-II without increasing the implementation cost. From practical viewpoint, the primal application of our result would be the construction of small-scale block ciphers, where many ciphers are recently proposed in this category [4] [11]. Additionally, it will also be useful to build large-block ciphers, such as 256 or 512-bit block.…”

“…Recently, Type-II GFS receives a lot of attention for its simplicity and high parallelism. We have some modern Type-II-based block ciphers, e.g., CLEFIA [25] (k = 4), and HIGHT [11] (k = 8). When the length of message is fixed, the width (i.e., I/O lengths) of round function gets shorter as the partition number grows.…”

Abstract. The generalized Feistel structure (GFS) is a generalized form of the classical Feistel cipher. A popular version of GFS, called Type-II, divides a message into k > 2 sub blocks and applies a (classical) Feistel transformation for every two sub blocks, and then performs a cyclic shift of k sub blocks. Type-II GFS has many desirable features for implementation. A drawback, however, is its low diffusion property with a large k. This weakness can be exploited by some attacks, such as impossible differential attack. To protect from them, Type-II GFS generally needs a large number of rounds.In this paper, we improve the Type-II GFS's diffusion property by replacing the cyclic shift with a different permutation. Our proposal enables to reduce the number of rounds to attain a sufficient level of security. Thus, we improve the security-efficiency treading off of Type-II GFS. In particular, when k is a power of two, we obtain a significant improvement using a highly effective permutation based on the de Bruijn graph.

“…XTEA is vulnerable to related key differential attack. Like SEA, HIGHT [12] is also another Block Cipher for resource constrained systems, but it is non-scalable and consumes more number of gates and the throughput and operating frequency are much less when compared to SEA. So, implementing SEA for constrained systems is a better option.…”

SEA -Scalable Encryption Algorithm is a block cipher based symmetric encryption scheme, specially designed for resource constrained devices. SEA proposes low computational encryption routines (i.e. less code size, memory and power) for processors with a restricted instruction set. SEA is parametric with plain-text, key and microprocessor size, and meant for efficient combination of encryption/decryption and key derivation. The performance of modified SEA using efficient architectures of 2 b and 2 b -1 modular adders in a Field programmable gate array (FPGA) device is investigated. In this paper, an iterative based loop design of the block cipher is first implemented on FPGA. The proposed modular adders in SEA achieve lower area and power consumption on the target platform VIRTEX-4, xc4vl25-10ff668. Beyond its low cost performances, the proposed architecture is fully flexible with any parameters and takes advantage of generic VHDL coding.
