“…To avoid the feeble keys recognized in the earlier DDP-based ciphering techniques, Switchable procedures are proposed in Cobra-H64 and Cobra-H128 [8]. Moreover, though these ciphers are suitable for high speed hardware architectures, they are identified to be area inefficient.…”

Our proposed method L2D-CASKE, the lightweight 2-dimensional (2-D) Cellular Automata (CA) based symmetric key encryption algorithm is a 128 bit length that allows a key length of 128 bits. It is designed as a lightweight encryption algorithm. As being light weight, it can be easily applied on small devices such as wireless sensor motes, smart cards and other PDAs. An encryption algorithm having simple loop operations, based on iterative parameters is used in this work. A number of sequences and operations are used for this purpose. In this paper, the well designed algorithm was verified using MATLAB 7.7 (R2008) tool and the hardware synthesized on Field Programmable Gate Arrays (FPGAs). To achieve this, our algorithm uses loop design based on iterations and the same is realized on FPGA. Advantages of our algorithm can be listed in terms of its flexibility for a set of given constraints, less complexity involved in its performance. This is achieved through the usage of generic VHDL coding. Virtex-4 XC4VL25 -10ff668 is used as a test device in Xilinx 9.1 for realizing our algorithm.

“…Thus, due to non-linearity and better DCs the F 2/1 and F 2/2 elements are significantly more attractive as cryptographic primitives than P 2/1 . Replacing the switching elements P 2/1 by CEs F 2/1 or F 2/2 in the linear DDP boxes (a number of which are considered in [17,13] we get non-linear DDO boxes with significantly advanced contribution to the avalanche. While FPGA implementation, this improvement does not increase the cost, since the switching elements and arbitrary CEs of the F 2/1 and F 2/2 types are implemented using the same hardware resources.…”

“…The DDPs have been used as main design primitive in a number of fast block ciphers CIKS-1 [10], Spectr-H64 [11], Cobra-H64 [12], and Cobra-H128 [13] suitable to cheap hardware implementation). Security analysis of these ciphers has shown that efficiency of the DDPs as cryptographic primitive is caused by the variability of this operation while ciphering different data blocks.…”

This work considers the problem of increasing the performance of the ciphers based on Data-Dependent (DD) operations (DDO) for VLSI implementations. New minimum size primitives are proposed to design DDOs. Using advanced DDOs instead of DD permutations (DDP) in the DDP-based iterative ciphers Cobra-H64 and Cobra-H128 the number of rounds has been significantly reduced yielding enhancement of the "performance per cost" value and retaining security at the level of indistinguishability from a random transformation. To obtain further enhancement of this parameter a new crypto-scheme based on the advanced DDOs is proposed. The FPGA implementation of the proposed crypto-scheme achieves higher throughput value and minimizes the allocated resources than the conventional designs. Design of the DDO boxes of different orders is considered and their ASIC implementation is estimated.

COSB-128 is a type of fast controllable permutation block (CPB), which is designed to ensure a high speed of data transformation and high stability to differential analysis. In this paper, we present the possibility to distinguish between a 10-round COSB-128 and a 128-bit random permutation through a full 10-round related-key difference characteristic by proposing a distinguishing attack with high probability on this cipher. This attack is another result from previous study of related-key attack on . From that point, it reveals the potential to extend to the related-key recovery attack on this algorithm in the future.
