An interesting way to partition a number

INFORMATION PROCESSING LETTERS 1999年第3-4期71卷 141-148页

作者： Bhatt, PCP Kochi Univ Technol Tosayamada Kochi 7828502 Japan

This note reports an interesting kind of partition, called an s-partition, for a natural number n. Each cell in an s-partition has an element of the form 2(r) - 1. We give a recurrence relation to enumerate all s-partitions of it and also derive an upper bound on the number of possible s-partitions. We define a relation of domination to get a lexical order on s-partitions and show that a unique partition, called d-partition, dominates all other s-partitions of n. A d-partition has the smallest cardinality of O(log n) and can be generated in O(log n) steps. A d-partition may have a potential application in cryptography as we demonstrate its use in a distributed algorithm to compute a(n) mod m, a key computation intensive step in many cryptographic algorithms.

The cryptographic algorithm has been gradually improved in design, but its implementations are vulnerable to side-channel analysis (SCA). Generally speaking, adding a mask to the primitive is the best way to counteract SCA. In the high-order mask, the key to affecting performance and security lies in the multiplication design. Based on the research of the advanced encryption standard (AES) algorithm, internal round function structure, and zero-knowledge proof, a high-order AES mask scheme is designed to optimise the implementation. In this scheme, the substitution-box protects sensitive variables in the algorithm with the use of secure multiplication and secure inversion by column. The scheme named as in columns higher-order mask (ICHM), features low cost and high security. The result of the experiment proves the security and effectiveness of the ICHM.

JOURNAL OF AMBIENT INTELLIGENCE AND HUMANIZED COMPUTING 2019年第7期10卷 2633-2643页

Due to the cost, power requirements and capacity, data are mainly stored off-chip rather than on-chip in embedded systems. The data exchanged between the processor and off-chip memory might be sensitive, security and efficiency of off-chip memory is a major concern in embedded systems. However, existing protection solutions often require significant overhead to achieve adequate protection. This paper proposes a security management method which can guarantee stronger data confidentiality and integrity with a reduced overhead in area, memory footprint, and performance cost. To reduce on-chip memory consumption and latency cost, protection scheduling and storage strategy are carefully studied, then our security management architecture is formed. Afterwards, confidentiality and integrity modules are designed respectively. Data confidentiality is protected through a Binary Additive Stream Cipher-AES-Time Stamp based on circuit and addresses scrambling network of Benes, and data integrity is safeguarded through an integrity checking module based on SHA3-TAH and MSet-XOR-Hash tree. Hardware implementation is designed and synthesized in a 0.18 mu m process. The experiment area is about 1.1mm(2) while frequency reaches 563MHz. The attack complexity is more than 2(224) while additional storage consumption is limited in about 26.6%.

According to the grey data generating techniques in grey system theory, we propose a novel cryptosystem, whose applications can develop a new direction in the field of information security. In this paper, we present the concepts of sum-lock, difference-lock, sum-ladder, and difference-ladder. By using these concepts, we can obtain a cryptosystem with lock generation and sum-difference replacement ladder. In addition, we provide the encryption and decryption algorithms of our cryptosystem and adopt an illustrative example to verify it.

IEEE DESIGN & TEST OF COMPUTERS 2007年第6期24卷 544-545页

作者： Kim, Chong Hee Quisquater, Jean-Jacques Univ Catholique Louvain Dept Elect Engn Crypto Grp B-1348 Louvain Belgium

In a fault attack, errors are induced during the computation of a cryptographic algorithm, and the faulty results are exploited to extract information about the secret key in embedded systems. Fault attacks can break an unprotected system more quickly than any other kind of side-channel attack. Furthermore, protecting against fault attacks is more costly in terms of chip area. This sidebar surveys fault injection methods, types of faults, and fault attack models.

INFORMATION TECHNOLOGY - SECURITY TECHNIQUES AND STANDARDIZATION

引用

COMPUTER STANDARDS & INTERFACES 1995年第1期17卷 63-67页

作者： KRAUSE, L NATL RES CTR COMP SCI GMDD-52737 ST AUGUSTINGERMANY

A brief history of international standardization of IT security techniques is given beginning with the first working group within ICO/TC97 in 1980. Nowadays security is dealt with by an increasing number of standardization committees. Many of these however are considering security techniques within the framework of other topics such as architecture or special applications. The GMD participates in some of these committees especially in the subcommittee ISO/IEC JTC 1/SC 27 which is standardizing generic IT security techniques and mechanisms. The emphasis of this article is on the work of SC27. The scope and a short description of the programme of work of SC27 is given including the most important security mechanisms based on cryptography relating, for instance, to authentication, access control, confidentiality, data integrity, and non-repudiation. The results of a discussion, whether cryptographic algorithms should be standardized or not, are described. The classification of IT security standards is given to set up a link to the environment of IT security techniques and mechanisms.

A CAD approach for pre-layout optimal PDN design and its post-layout verification

引用

MICROPROCESSORS AND MICROSYSTEMS 2019年 65卷 158-168页

Design of power distribution network (PDN) draws great attention to integrated circuit (IC) designers as it directly affects the circuit performance. The challenge is to immune the circuit from the noise arising due to PDN by means of effective placement of decoupling capacitance (decap) with optimal power, delay, energy and area utilization. Our work involves extraction of circuit parameters in the pre-layout stage and estimating decoupling capacitance as an early prediction activity based on dynamic power dissipation. We propose a new modular pre-layout PDN (MPLPDN) design approach, which modularizes the circuit and involves a computer aided design (CAD) methodology to investigate the changes in noise, power and delay parameter based on predictive decap allocation across the modules. A pruning methodology has been adopted to choose the best combination of the modules. The modularization algorithm is applied in a bottom up approach i.e. the lower level modules are combined at first and the top level module is created at the last stage. The experimental results based on pre and post layout simulation of application circuits show that MPLPDN achieves a considerable PDN noise suppression with a negligible increase in power, delay, energy and area. The comparison between pre-layout and post-layout simulation results also establishes the correctness of our early prediction. (C) 2019 Elsevier B.V. All rights reserved.

In recent days, cryptographic algorithm hardware is the need of IoT devices. However, limited resources demand an efficient approach towards designing the said cryptographic algorithm hardware. This paper introduces the PUF (Physical Unclonable Function) based approach to design the key generator used in cryptographic algorithm hardware to minimize the area and power consumption. A customizable key generation unit has been introduced in the form of a Standard Synchronization Unit (SSU) to match the desired key size requirements. The results were generated with PUF based designs from literature and compared with the proposed PDL (Programmable Delay Logic) PUF. All parameters considered, a proposed PDL PUF key generator is an efficient option that can be integrated with an Advanced Encryption System (AES) as the key generator. The modified AES design result was compared with the literature's results on the Xilinx Virtex XC7VX690T platform. The modified AES is an efficient solution with 12.10% less area consumption and a 44.51% increase in throughput.

Modern power grid is the most complex human-made system, which is monitored by wide-area monitoring system (WAMS). Providing time-synchronized data of power system operating states, WAMS will play a crucial role in next generation smart grid protection and control. WAMS helps secure efficient energy transmission as well as reliable and optimal grid management. As the key enabler of a smart grid, numerous sensors such as PMU and current sensors transmit real-time dynamic data, which is usually protected by encryption algorithm from malicious attacks, over wide-area-network (WAN) to power system control centers so that monitoring and control of the whole system is possible. Security algorithms for power grid need to consider both performance and energy efficiency through code optimization techniques on encryption and decryption. In this paper, we take power nodes (sites) as platforms to experimentally study ways of energy consumptions in different security algorithms. First, we measure energy consumptions of various security algorithms on CrossBow and Ember sensor nodes. Second, we propose an array of novel code optimization methods to increase energy consumption efficiency of different security algorithms. Finally, based on careful analysis of measurement results, we propose a set of principles on using security algorithms in WAMS nodes, such as cryptography selections, parameter configuration, and the like. Such principles can be used widely in other computing systems with energy constraints.

COMPUTERS & ELECTRICAL ENGINEERING 2018年 72卷 766-773页

作者： Amutha, S. Balasubramanian, Kannan PSR Engn Coll Dept Comp Sci & Engn Sivakasi Virudhunagar India Mepco Schlenk Engn Coll Dept Comp Sci & Engn Sivakasi Virudhunagar India

A Mobile Ad hoc network (MANET) forms a group of mobile nodes which are active and exchange messages using interconnections between the nodes. The mobile network is the new generation of wireless network and differs from the wired network in the use of power-aware routing protocols, ease of routing configuration and network infrastructure. The proposed work identifies and resolves the black hole attack and provides security to the routing protocol by using a secured energy-optimized expanding ring search (ERS) algorithm. Also, this technique reduces the energy consumption and improves the network lifetime. In addition, this work focuses on improving the packet delivery ratio (PDR), throughput and security using the advanced encryption standard (AES) cryptographic algorithm. (C) 2017 Elsevier Ltd.
