Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 5,   Pages 688-702 doi: 10.1631/FITEE.2200468

Abstract: (PM) s have been developed to achieve high performance by exploiting the advanced features of PMs, including nonvolatility, byte addressability, and dynamic random access memory (DRAM) like performance. Unfortunately, these PMs suffer from limited write endurance. Existing space management strategies of PM s can induce a severely unbalanced wear problem, which can damage the underlying PMs quickly. In this paper, we propose a -aware , called WMAlloc, to achieve the wear leveling of PMs while improving the performance of s. WMAlloc adopts multiple min-heaps to manage the unused space of PMs. Each heap represents an allocation granularity. Then, WMAlloc allocates less-worn blocks from the corresponding min-heap for allocation requests. Moreover, to avoid recursive split and inefficient heap locations in WMAlloc, we further propose a bitmap-based multi-heap tree (BMT) to enhance WMAlloc, namely, WMAlloc-BMT. We implement WMAlloc and WMAlloc-BMT in the Linux kernel based on NOVA, a typical PM . Experimental results show that, compared with the original NOVA and dynamic wear-aware range management (DWARM), which is the state-of-the-art -aware allocator of PM s, WMAlloc can, respectively, achieve 4.11× and 1.81× maximum write number reduction and 1.02× and 1.64× performance with four workloads on average. Furthermore, WMAlloc-BMT outperforms WMAlloc with 1.08× performance and achieves 1.17× maximum write number reduction with four workloads on average.

Abstract: Emergence of new hardware, including and , has brought new opportunities to design. In this paper, we design and implement a new named NICFS based on and SmartNIC. We divide the into two parts: the front end and the back end. In the front end, data writes are appended to the in a log-structured way, leveraging the fast persistence advantage of . In the back end, the data in logs are fetched, processed, and patched to files in the background, leveraging the processing capacity of SmartNIC. Evaluation results show that NICFS outperforms Ext4 by about 21%/10% and about 19%/50% on large and small reads/writes, respectively.

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 11,   Pages 1578-1586 doi: 10.1631/FITEE.1800458

Abstract: based on cryptography is a new paradigm in the field of nanotechnology. The overall performance of QCA is high compared to traditional complementary metal-oxide semiconductor (CMOS) technology. To achieve data security during nanocommunication, a cryptography-based application is proposed. The devised circuit encrypts the input data and passes it to an output channel through a cum data path selector, where the data is decrypted back to its original form. The results along with theoretical implication prove the accuracy of the circuit. Power dissipation and circuit complexity of the circuit have been analyzed.

The Cryptographic Properties of Select Logic Functions

Liang Zeng,Li Shiqu

Strategic Study of CAE 2005, Volume 7, Issue 7,   Pages 50-54

Abstract:

In this paper, the main results are concerned with the Walsh transform and the autocorrelation function of select logic functions. Select logic functions with large number of variables have perfect stability and can resist towards cryptanalysis of best affine approximation, but they can't resist towards differential cryptanalysis efficiently because of weak propagation property. By a linear transformation of coordinates, an explicit construction for functions satisfying the strict avalanche criterion or Being correlation immune is provided.

Mengni BIE, Wei LI, Tao CHEN, Longmei NAN, Danyang YANG,raspberry0213@126.com,liwei12@fudan.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 1,   Pages 134-144 doi: 10.1631/FITEE.2000325

Abstract: RSA and ellipse curve cryptography (ECC) algorithms are widely used in authentication, data security, and access control. In this paper, we analyze the basic operation of the ECC and RSA algorithms and optimize their modular multiplication and modular inversion algorithms. We then propose a modular operation architecture, with a mix-memory unit and double multiply-accumulate structures, to realize our unified, asymmetric cryptosystem structure in an operational unit. Synthesized with 55-nm CMOS process, our design runs at 588 MHz and requires only 437 801 μm of hardware resources. Our proposed design takes 21.92 and 23.36 mW for 2048-bit RSA modular multiplication and modular inversion respectively, as well as 16.16 and 15.88 mW to complete 512-bit ECC dual-field modular multiplication and modular inversion respectively. It is more energy-efficient and flexible than existing single algorithm units. Compared with existing multiple algorithm units, our proposed method shows better performance. The operation unit is embedded in a 64-bit RISC-V processor, realizing key generation, encryption and decryption, and digital signature functions of both RSA and ECC. Our proposed design takes 0.224 and 0.153 ms for 256-bit ECC point multiplication in and respectively, as well as 0.96 ms to complete 1024-bit RSA exponentiation, meeting the demand for .
