Authenticated Encryption (AE) and Authenticated Encryption with Associated Data (AEAD) play a significant role in cryptography as they simultaneously provide confidentiality, integrity, and authenticity assurances on the data. The Competition for Authenticated Encryption, Security, Applicability, and Robustness (CAESAR) seeks optimal authenticated ciphers based on multiple criteria, including security, performance, area, and energy-efficiency. Low power consumption is one of the main requirements for any chip design targeting the Internet of Things (IoT) applications. In this research paper, low area and low power implementations of selected ciphers from the CAESAR candidates namely NORX, Tiaoxin, SILC, COLM, and JAMBU are provided and Implemented in both Application Specific Integrated Circuits (ASIC) and Field Programmable Gate Arrays (FPGA). For FPGA Implementations a reduction in area with an average of 32% and a reduction in dynamic power with an average of 56% are achieved compared to their corresponding high-speed architectures. While for ASIC Implementations a reduction in area with an average of 36% and a reduction in dynamic power with an average of 43% are achieved compared to their corresponding high-speed architectures. Moreover, throughput (TP) decreases by an average of 70%.

Ascon v1.2: Lightweight Authenticated Encryption and Hashing

et al. 2021

View full text Add to dashboard Cite

Authenticated encryption satisfies the basic need for authenticity and confidentiality in our information infrastructure. In this paper, we provide the specification of Ascon-128 and Ascon-128a. Both authenticated encryption algorithms provide efficient authenticated encryption on resource-constrained devices and on high-end CPUs. Furthermore, they have been selected as the “primary choice” for lightweight authenticated encryption in the final portfolio of the CAESAR competition. In addition, we specify the hash function Ascon-Hash, and the extendable output function Ascon-Xof. Moreover, we complement the specification by providing a detailed overview of existing cryptanalysis and implementation results.
