ABSTRACT In 2010, a new cipher Hummingbird by [Engels, D.-Fan, X.- -Gong, G.-Hu, H.-Smith, E. M. Hummingbird: Ultra-Lightweight Cryptography for Resource-Constrained Devices, in: 1st International Workshop on Lightweight Cryptography for Resource-Constrained Devices. Tenerife, Canary Islands, Spain, January 2010] was proposed. It is a combination of both block and stream cipher and its design was inspired and motivated by the Enigma machine. The encryption process of the cipher can be considered as a continuous running of a rotor-cipher. Four block ciphers play the role of the rotors that apply the permutation to the 16-bit words. This cipher motivated us to investigate a new cipher design based on a Fialka cipher machine. Fialka M-125 is an Enigma based rotor-cipher machine used during the Cold War. It is considered one of the most secure cipher machines. Advantages of this cipher are based on the elimination of the Enigma’s known weaknesses. There are no known attacks on this cipher. In this paper we introduce a new cipher based on the Fialka machine. We transform the Fialka encryption algorithm to a modern stream cipher. The rotors are represented as S-boxes and shift registers are used to provide the rotor clocking. We propose three different versions of the cipher and investigate the statistical properties of their outputs. In the article we also provide basic implementation details and basic performance analysis.

Abstract The information transmitted in IoT is susceptible to affect the user’s privacy, and hence the information ought to be transmitted securely. The conventional method to assure integrity, confidentiality, and non-repudiation is to first sign the message and then encrypt it. Signcryption is a technique where the signature and the encryption are performed in a single round. The current Signcryption system uses traditional cryptographic approaches that are overloaded for IoT, as it consists of resource-constrained devices and uses the weak session key to encrypt the data. We propose a hybrid Signcryption scheme that employs PRESENT, a lightweight block cipher algorithm to encrypt the data, and the session key is encrypted by ECC. The time taken to signcrypt the proposed Signcryption is better when compared to current Signcryption techniques, as it deploys lightweight cryptography techniques that are devoted to resource-constrained devices.

IoT and cloud computing are the novel fields that are rapidly progressing in the world of internet technology. A huge and massive amount of data are communicating via IoT and cloud devices. Along with the highly configured devices, IoT and cloud also empowered many resource-constrained devices to communicate and compute information through network. But the major problem that they face is how to provide data security through conventional cryptographic algorithms in such resource-constrained devices having smaller size, limited memory spaces, low computation capabilities, and limited power. In this scenario, the biggest driver towards the problem is lightweight cryptography (LWC). This chapter discusses thoroughly the LWC, different schemes of LWC, and cryptanalysis of different LWC schemes.

Lightweight cryptography is an important element in smart devices that require data security as one of the features. These smart devices utilize cryptography when transferring sensitive data. Most of the smart devices are resource constrained devices and thus possess limited computing capability and low memory space. The PHOTON hash function algorithm is a promising lightweight cryptography approach for resource-constrained devices. It has a complex operation called MixColumns. This paper presents a new MixColumns architecture for PHOTON implemented on Field Programmable Gate Array (FPGA) device. In our design, the number of complex multiplication opera-tions is reduced by utilizing comparators that are based on four-bit Galois operations. The efficient PHOTON hardware design was coded using a very high speed integrated circuit hardware description language, VHDL. The design was successfully synthesized, mapped, simu-lated and tested on two FPGA evaluation boards namely, Sparten3 and Artix-7. The results show that the proposed design achieve a throughput of 582 Mbps and an efficiency of 1.55 Gbps/slice for Spartan3, while a throughput of 1.41 Gbps and efficiency of 8.66 Gbps/slice are obtained for Artix-7. The performance on both platforms has superseded performance of existing implementations in litera-ture.
