“…The FL KECCAK architecture achieves 16.49 Gbps throughput which becomes almost double for LU2 architecture. The FL and LU2 KECCAK achieve better throughput than [27,[30][31][32][33][34][35][36][37][38][39][40]. Table 3 shows, the two-stage pipeline adopted in PP2-LU2 architecture achieved better throughput than the fastest KECCAK until date proposed in [41].…”

Internet protocol security (IPSec), secure sockets layer (SSL)/transport layer security (TLS) and other security protocols necessitate high throughput hardware implementation of cryptographic functions. In recent literature, cryptographic functions implemented in software, application specific integrated circuit (ASIC) and field programmable gate array (FPGA). They are not necessarily optimized for throughput. Due to the various side-channel based attacks on cache and memory, and various malware based exfiltration of security keys and other sensitive information, cryptographic enclave processors are implemented which isolates the cryptographically sensitive information like keys. We propose a partitioned enclave architecture targeting IPSec, TLS and SSL where the partitioned area ensures that the processor data-path is completely isolated from the secret-key memory. The security processor consists of a Trivium random number generator, Rivest-Shamir-Adleman (RSA), advanced encryption standard (AES) and KECCAK cryptos. We implement three different optimized KECCAK architectures. The processing element (PE) handles all communication interfaces, data paths, and control hazards of network security processor. The memory of KECCAK and AES communication is done via a direct memory access controller to reduce the PE overhead. The whole system is demonstrated by FPGA implementation using Vivado 2015.2 on Artix-7 (XC7A100T, CSG324). The performances of the implemented KECCAKs are better in terms of security, throughput and resource than the existing literature.

“…Even if the interface allows the user to enter inputs and extract outputs incrementally, everything fits in the 384 bits of the permutation plus a couple of pointers for bookkeeping. In a different (i.e., non-lightweight) context, Yalla et al showed the benefits of such a construction in terms of area in a hardware implementation [YHK15]. Not surprisingly, many candidates to the NIST Lightweight Cryptography Standardization Process adopted the same strategy [DHP + 19].…”

In this paper, we present Xoodyak, a cryptographic primitive that can be used for hashing, encryption, MAC computation and authenticated encryption. Essentially, it is a duplex object extended with an interface that allows absorbing strings of arbitrary length, their encryption and squeezing output of arbitrary length. It inherently hashes the history of all operations in its state, allowing to derive its resistance against generic attacks from that of the full-state keyed duplex. Internally, it uses the Xoodoo[12] permutation that, with its width of 48 bytes, allows for very compact implementations. The choice of 12 rounds justifies a security claim in the hermetic philosophy: It implies that there are no shortcut attacks with higher success probability than generic attacks. The claimed security strength is 128 bits. We illustrate the versatility of Xoodyak by describing a number of use cases, including the ones requested by NIST in the lightweight competition. For those use cases, we translate the relatively detailed security claim that we make for Xoodyak into simple ones.

“…A more recent configurable co-processor, CoARX, exploits operational similarity between cryptographic functions to implement different block ciphers, hash functions, stream ciphers that are based on ARX family of ciphers [27]. FPGA implementation of AES and Keccak multi functional cores have been compared with each other in [28].…”
