Secure, efficient execution of AES is an essential requirement on most computing platforms.
Dedicated Instruction Set Extensions (ISEs) are often included for this purpose. RISC-V is a …

In recent years, some countermeasures against Differential Power Analysis (DPA) at the
logic level have been proposed. At CHES 2005 conference, Popp and Mangard proposed a …

Secure communication over public networks like the Internet requires the use of
cryptographic algorithms as basic building blocks. Most cryptographic workloads pose a …

A flexible instruction set for a general purpose processor is provided. The instruction set
includes instructions to perform a “one round” pass for encryption or decryption and also …

This paper describes a high performance, low power, and highly flexible cryptographic
processor, Cryptoraptor, which is designed to support both today's and tomorrow's …

Framed within the general context of cyber-security, standard cryptographic constructions
often represent an enabling technology for associated solutions. Alongside or in …

In recent years, different instruction set extensions for cryptography have been proposed for
integration into general-purpose RISC processors. Both public-key and secret-key …

Bit-slicing is a non-conventional implementation technique for cryptographic software where
an n-bit processor is considered as a collection of n 1-bit execution units operating in SIMD …

In this work, we provide a software benchmark for a large range of 256-bit blockcipher-
based hash functions. We instantiate the underlying blockcipher with AES, which allows us …

Notwithstanding the tremendous increase in performance of desktop computers, more and
more computational work is performed on small embedded microprocessors. Particularly …
