“…There have been a number of results demonstrating record-breaking FPGA implementations [8,23], some with side channel mitigations [12,28], and highly efficient microcontroller implementations [11,17,20]. Novel uses have been proposed, including explorations showing the suitability of Simon in the decidedly non-lightweight realm of homomorphic encryption [27,18].…”

Invited ABSTRACTThe Simon and Speck families of block ciphers were designed specifically to offer security on constrained devices, where simplicity of design is crucial. However, the intended use cases are diverse and demand flexibility in implementation. Simplicity, security, and flexibility are ever-present yet conflicting goals in cryptographic design. This paper outlines how these goals were balanced in the design of Simon and Speck.

“…Because of its lightweight structure, SIMON circuit has weak resistance to power analysis attack. Some studies have clearly demonstrated or implemented the crack of SIMON circuits through power analysis such as Refs [2,8,10,11]. The purpose of this section is to show intuitively through analysis and experiment that the SIMON circuit can be cracked by simple differential power analysis.…”

“…The encrypted operation of fault plaintext is randomly inserted into the first half cycle or the second half cycle of normal encrypted operation by double rate technology so that the attacker cannot accurately locate the position of each round of encryption operations in the power curve. Compared with existing countermeasure based on the threshold implementation and bool mask [2,6,11], our scheme is area-efficient.…”

Differential power analysis (DPA) is an effective side channel attack method, which poses a critical threat to cryptographic algorithms, especially lightweight ciphers such as SIMON. In this paper, we propose an area-efficient countermeasure against DPA on SIMON based on the power randomization. Firstly, we review and analyze the architecture of SIMON algorithm. Secondly, we prove the threat of DPA attack to SIMON by launching actual DPA attack on SIMON 32/64 circuit. Thirdly, a low-cost power randomization scheme is proposed by combining fault injection with double rate technology, and the corresponding circuit design is implemented. To the best of our knowledge, this is the first scheme that applies the combination of fault injection and double rate technology to the DPA-resistance. Finally, the t-test is used to evaluate the security mechanism of the proposed designs with leakage quantification. Our experimental results show that the proposed design implements DPA-resistance of SIMON algorithm at certain overhead the cost of 47.7% LUTs utilization and 39.6% registers consumption. As compared to threshold implementation and bool mask, the proposed scheme has greater advantages in resource consumption.

“…7 and reported in [68], in every clock cycle, 1-bit of internal state is processed. So if the circuit takes nbit size plaintext as input, n/2-clock cycles will be required to complete the whole round.…”

An Evaluation of Lightweight Block Ciphers for Resource-Constrained Applications: Area, Performance, and Security

et al. 2017

In March 2017, NIST (National Institute of Standards and Technology) has announced to create a portfolio of lightweight algorithms through an open process. The report emphasizes that with emerging applications like automotive systems, sensor networks, healthcare, distributed control systems, the Internet of Things (IoT), cyber-physical systems, and the smart grid, a detailed evaluation of the so called light-weight ciphers helps to recommend algorithms in the context of profiles, which describe physical, performance, and security characteristics. In recent years, a number of lightweight block ciphers have been proposed for encryption/decryption of data which makes such choices complex. Each such cipher offers a unique combination of resistance to classical cryptanalysis and resource-efficient implementations. At the same time, these implementations must be protected against implementation-based attacks such as side-channel analysis. In this paper, we present a holistic comparison study of four lightweight block ciphers, PRESENT, SIMON, SPECK, and KHUDRA, along with the more traditional Advanced Encryption Standard (AES). We present a uniform comparison of the performance and efficiency of these block ciphers in terms of area and power consumption, on ASIC and FPGA-based platforms. Additionally, we also compare the amenability to side-channel secure implementations for these ciphers on ASIC-based platforms. Our study is expected to help designers make suitable choices when securing a given application, across a wide range of implementation platforms.
