NORX8 and NORX16: Authenticated Encryption for Low-End Systems
This paper presents NORX8 and NORX16, the 8-bit and 16-bit versions of the authenticated cipher NORX, one of the CAESAR candidates. These new versions are better suited for low-end systems—such as “internet of things” devices—than the original 32-bit and 64-bit versions: whereas 32-bit NORX requires 64 bytes of RAM or cache memory, NORX8 and NORX16 require just 16 and 32 bytes, respectively. Bo...
متن کاملNORX: Parallel and Scalable AEAD
This paper introduces NORX, a novel authenticated encryption scheme supporting arbitrary parallelism degree and based on ARX primitives, yet not using modular additions. NORX has a unique parallel architecture based on the monkeyDuplex construction, with an original domain separation scheme for a simple processing of header/payload/trailer data. Furthermore, NORX specifies a dedicated datagram ...
متن کاملAnalysis of NORX: Investigating Differential and Rotational Properties
This paper presents a thorough analysis of the AEAD scheme NORX, focussing on differential and rotational properties. We first introduce mathematical models that describe differential propagation with respect to the non-linear operation of NORX. Afterwards, we adapt a framework previously proposed for ARX designs allowing us to automatise the search for differentials and characteristics. We giv...
متن کاملBLAKE and 256-bit advanced vector extensions
Intel recently documented its AVX2 instruction set extension that introduces support for 256-bit wide single-instruction multiple-data (SIMD) integer arithmetic over double (32-bit) and quad (64-bit) words. This will enable Intel’s future processors—starting with the Haswell architecture, to be released in 2013—to fully support 4-way SIMD com putation of 64-bit ARX algorithms (32-bit is alread...
متن کاملImplementing BLAKE with AVX, AVX2, and XOP
In 2013 Intel will release the AVX2 instructions, which introduce 256-bit singleinstruction multiple-data (SIMD) integer arithmetic. This will enable desktop and server processors from this vendor to support 4-way SIMD computation of 64-bit add-rotate-xor algorithms, as well as 8-way 32-bit SIMD computations. AVX2 also includes interesting instructions for cryptographic functions, like any-to-a...
