Asic crypto accelerator
After seeing the growth of the computing market, hardware manufacturers are keen to jump onto the next trend; AI compute. Even as existing hardware such as GPUs and CPUs are being programmed to be better for training algorithms, solutions are emerging that promise an order-of-magnitude improvement over existing solutions. Training and running large AI algorithms take a lot of time. Therefore, there is a big need for a concept known as hardware acceleration.

In this paper, the REDEFINE polymorphic architecture is presented as an architecture framework that can optimally support a varied set of crypto algorithms without losing high performance. The presented solution is capable of accelerating the advanced encryption standard AES and elliptic curve cryptography ECC cryptographic protocols, while still supporting different lavors of these algorithms as well as different underlying inite ield sizes.
The compelling feature of this cryptosystem is the ability to provide acceleration support for new ield sizes as well as new possibly proprietary cryptographic algorithms decided upon after the cryptosystem is deployed. With quality-of-service based hardware units are replaced by more basic hardware units communications proliferating, there is also the need to be able to that can be dynamically recomposed to provide different rapidly tune the performance of these accelerators according to functionalities required to accelerate higher-level applications.
Such through a NoC. The REDEFINE platform includes its own circumstances make it an attractive proposition to have a compiler1,2, which performs this decomposition in an extremely uniied cryptographic accelerator that can accelerate at least a eficient, hardware-aware manner.
Since, application synthesis canonical set of existing cryptographic algorithms, while still in REDEFINE is from a high level speciication in C, new providing some means to support performance tuning as well applications as well as application enhancements decided upon as new cryptographic algorithms.
Of course, it is vital not to after deployment can be easily realised within the REDEFINE lose too much of the high performance that makes specialised framework, by simply creating a new software functional accelerators attractive, in the process.
In communications where the highest possible security Further, the REDEFINE framework allows the is absolutely necessary, for instance in national security customisation of the basic processing units within the related communications, moving away from standards based architecture, in order to support special instructions algorithms and devising custom cryptographic algorithms is accelerating the common low-level operations occurring in all an option that is desirable and often practiced.
It may also be the applications. Processing units thus added are called custom desired to change the crypto algorithm in use at a particular functional units CFUs. This makes it possible to integrate time on-the-ly. If high performance is needed together with ASIC-like speed of execution, with the lexibility coming proprietary algorithms, one simply cannot obtain a solution from being able to describe applications in C, which is an ideal in currently available cryptographic accelerators.
Designing combination for uniied accelerator for different existing as a uniied platform for this purpose requires a careful shift well as proprietary cryptographic algorithms. When designing a lexible Listing 1. The throughput obtained for the AES application is code to generate HyperOps that span an appropriate listed in Table 1.
An example mapping of the AES 3. A snippet of the corresponding Elliptic curve cryptography ECC -based algorithms basically operate on a subset of points over an elliptic curve. The coordinates of these points are deined over an underlying inite ield or Galois ield. The central operation in all ECC-based protocols is the point scalar multiplication operation5,10, The performance of all ECC-based schemes is inally determined by the performance of multiplication in the underlying inite ield8.
The numbers show the used the Montgomery algorithm for the random base mapping of data blocks onto CEs while running 10 AES instances in point case, and the ixed base comb method for the parallel. Some of the sections are Algorithm Performance reproduced here to illustrate the essential concepts. Knezevic3, et al. Equation 1 shows the reduction process in this case3.
The hierarchy of operations in the elliptic curve point From Eqn 1 it is evident the reduction process requires scalar multiplication operation. Note that, the module and inite ield operations is accelerated by using CFUs. Thus, we use division operations in the two methods translate to partitioning two CFUs, one for GF 2m squaring of a term polynomial and of the polynomials into lower and higher half and therefore do one for polynomial multiplication of two term polynomials not require any arithmetic operation.
These CFUs can be used in a scalable manner, i. It should also be noted that The general purpose method of performing reduction the only other operations involved in reduction are addition is repeated subtractions or equivalent , which is too slow over GF 2m.
Since, there is no carry involved in addition, to be of use in practice, especially for the inite ield sizes addition of two m-bit polynomials which span more than one of cryptographic importance. However, xOR operations. Multiplication on the other hand requires these schemes assume the modulus of the inite ield to be multi-word shift and accumulation of results.
Consider the a priori decided, and this is where the lexibility of the crypto two polynomials C x and P x of degree m and k respectively. Eqn 2 implementation of the fast reduction methods, that can scale shows the representation. Arrangement of partial products. The product of these in Fig. As can be seen from Fig. This added hardware as shown entire polynomial C x and xr can be computed as follows: inside the shaded rectangle in Fig.
Hence forward we will refer to 3. In a w-bit instance of the multiplier, two sets Figure 3 shows how the partial products are aligned. The irst set of w two input AND gates are used for masking the irreducible polynomial 3. The second set of w two input as a Hardware Assist for Reduction AND gates are used for enabling two-word shift operation.
A reduction method is only as fast as the underlying This increase in hardware complexity is compensated by the multiplication operations. Therefore it is obvious that signiicant reduction in the number of operations brought about polynomial multiplication kernels are the candidates by using this multiplier as a hardware assist for reduction.
Therefore each word in the input polynomial C x produces a pair of words and these pairs need to be added i. In this subsection we propose a technique for combining the addition operations with the polynomial multiplications. Instead of considering one word of the polynomial C x we focus on one word of the partial product i.
Ci, j x. It is evident from Eqn 5 that to produce Ci,j x two words from the polynomial C x and one word from P x are necessary. In a shift-and-add IGF multiplier, the multiplicand operand is successively left shifted and the multiplier operand is used to selectively accumulate the results of the left shift operations. The IGF multiplier always produces a reduced result. Reduction over large ields Figure 4.
One stage of the modiied IGF multiplier. The proposed reduction method also leads to a reduction 5. Table 1 details the performance obtained on the The overall system architecture is shown in Fig. Supporting of the component modules using Synopsys Design Compiler, non-streaming applications in the context of Fig. The results in Table 1 are For streaming applications, it would be beneicial to make an comparable to the performance of individual accelerators for application stay on the computation fabric for an indeinite the respective algorithms available in the market.
As another amount of time, until end of streaming input is signaled by point of comparison, the OpenSSl implementation of the ECC some external entity. While the can be obtained again without changing any hardware, by speeds achieved are comparable to those listed in Table 1, introducing the while 1 loop.
A sample code snippet for a the power dissipation is signiicantly higher due to the higher streaming application is shown in listing 2.
Similarly, the results for the ECC point scalar multiplication with a ixed Listing 2. A code snippet for implementing a streaming application base point have been obtained with only points of storage.

A Flexible Crypto-system Based upon the REDEFINE Polymorphic ASIC Architecture
PQC introduces new mathematical elements and operations which are usually not easy to implement on standard processors. Especially for low cost and resource constraint devices, hardware acceleration is usually required. In addition, as the standardization process of PQC is still ongoing, a focus on maintaining flexibility is mandatory. RISQ-V efficiently reuses processor resources and reduces the amount of memory accesses. This significantly increases the performance while keeping the silicon area overhead low. We present three contributions.

This was fully ratified by the NIST in November , since which time AES has become the encryption algorithm of choice for all new commercial developments requiring a high degree of data security. AES is a bit block cipher, which supports a choice of three key sizes , and bits according to the level of security required. It is a fast and efficient algorithm, and is considered secure enough for most current data security applications; for example in the US Government approved it for use with classified US government data. Since its launch as a NIST standard, its use has become widespread across the world, where it forms the basis for many security protocols; for example There are more details on these cores below.
