“…Of course, our baseline implementation on MSP430 can be improved by using assembly codes. A recent work on similar ciphers (SPECK‐96) shows that assembly coding can improve the efficiency on MSP430 by 4× [29] which is, as expected, not enough to compensate for an efficiency gap of three orders of magnitude. Moving to a dedicated solution [5] further improves the efficiency at the expense of flexibility.…”

“…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.

“…Indeed, several improvements have been realized to reach this goal in both hardware and software implementations. Examples of these variations include AES-128 hardware ASCI implementation with 2400 Gate Equivalents (GE) is presented in [13], while efficient software AES implementations for 8-bit in [14], 16-bit in [15] and 32-bit in [16]. Moreover, AES optimized instructions were added to the instruction set of Intel's [17,18].…”

With the exponential growth in Internet-of-Things (IoT) devices, security and privacy issues have emerged as critical challenges that can potentially compromise their successful deployment in many data-sensitive applications. Hence, there is a pressing need to address these challenges, given that IoT systems suffer from different limitations, and IoT devices are constrained in terms of energy and computational power, which renders them extremely vulnerable to attacks. Traditional cryptographic algorithms use a static structure that requires several rounds of computations, which leads to significant overhead in terms of execution time and computational resources. Moreover, the problem is compounded when dealing with multimedia contents, since the associated algorithms have stringent QoS requirements. In this paper, we propose a lightweight cipher algorithm based on a dynamic structure with a single round that consists of simple operations, and that targets multimedia IoT. In this algorithm, a dynamic key is generated and then used to build two robust substitution tables, a dynamic permutation table, and two pseudo-random matrices. This dynamic cipher structure minimizes the number of rounds to a single one, while maintaining a high level of randomness and security. Moreover, the proposed cipher scheme is flexible as the dimensions of the input matrix can be selected to match the devices' memory capacity. Extensive security tests demonstrated the robustness of the cipher against various kinds of attacks. The speed, simplicity and high-security level, in addition to low error propagation, make of this approach a good encryption candidate for multimedia IoT devices.
