With the recent technological developments,massive vehicular ad hoc networks(VANETs)have been established,enabling numerous vehicles and their respective Road Side Unit(RSU)components to communicate with oneanother.The best way to enhance traffic flow for vehicles and traffic management departments is to share thedata they receive.There needs to be more protection for the VANET systems.An effective and safe methodof outsourcing is suggested,which reduces computation costs by achieving data security using a homomorphicmapping based on the conjugate operation of matrices.This research proposes a VANET-based data outsourcingsystem to fix the issues.To keep data outsourcing secure,the suggested model takes cryptography models intoaccount.Fog will keep the generated keys for the purpose of vehicle authentication.For controlling and overseeingthe outsourced data while preserving privacy,the suggested approach considers the Trusted Certified Auditor(TCA).Using the secret key,TCA can identify the genuine identity of VANETs when harmful messages aredetected.The proposed model develops a TCA-based unique static vehicle labeling system using cryptography(TCA-USVLC)for secure data outsourcing and privacy preservation in VANETs.The proposed model calculatesthe trust of vehicles in 16 ms for an average of 180 vehicles and achieves 98.6%accuracy for data encryption toprovide security.The proposedmodel achieved 98.5%accuracy in data outsourcing and 98.6%accuracy in privacypreservation in fog-enabled VANETs.Elliptical curve cryptography models can be applied in the future for betterencryption and decryption rates with lightweight cryptography operations.

cryptography circuits for portable electronic devices provide user authentication and secure data communication.These circuits should,achieve high performance,occupy small chip area,and handle several cryptographic algorithms.This paper proposes a highperformance ASIP(Application specific instruction set processor)for five standard cryptographic algorithms including both block ciphers(AES,Camellia,and ARIA)and stream ciphers(ZUC and SNOW 3G).The processor reaches ASIC-like performance such as 11.6 Gb/s for AES encryption,16.0 Gb/s for ZUC,and 32.0 Gb/s for SNOW3G,etc under the clock frequency of 1.0 GHz with the area consumption of 0.56 mm2(65 nm).Compared with stateof-the-art VLSI designs,our design achieves high performance,low silicon cost,low power consumption,and sufficient programmability.For its programmability,our design can offer algorithm modification when an algorithm supported is unfortunately cracked and invalid to use.The product lifetime of our design can thus be extended.

Quantum cryptography for Internet of Things Security

引用

Journal of Electronic Science and Technology 2019年第3期17卷 213-220页

作者： Alekha Parimal Bhatt Anand Sharma the Department of Computer Science and Engineering Mody University of Science and Technology

Internet of things (IoT) is a developing technology with a lot of scope in the future. It can ease various different tasks for us. On one hand, IoT is useful for us, on the other hand, it has many serious security threats, like data breaches, side-channel attacks, and virus and data authentication. Classical cryptographic algorithms, like the Rivest-Shamir-Adleman (RSA) algorithm, work well under the classical computers. But the technology is slowly shifting towards quantum computing, which has immense processing power and is more than enough to break the current cryptographic algorithms easily. So it is required that we have to design quantum cryptographic algorithms to prevent our systems from security breaches even before quantum computers come in the market for commercial uses. IoT will also be one of the disciplines, which needs to be secured to prevent any malicious activities. In this paper, we review the common security threats in IoT and the presently available solutions with their drawbacks. Then quantum cryptography is introduced with some of its variations. And finally, the analysis has been carried out in terms of the pros and cons of implementing quantum cryptography for IoT security.

White-box cryptography(WBC) aims to resist attacks from attackers who can control all the implementation details of cryptographic schemes. In 2009, Saxena et al. proposed a fundamental of white-box cryptography via the notion "white-box property"(WBP). Under this model, they proved that there do not exist obfuscators that can satisfy every security notion for a program(the negative result). On the other hand,they proved that there exists an obfuscator satisfying WBP for some security notion(the positive result). These contributions provide us a general cognition of WBC, which is big progress for the theoretical research. To better understand them, we make discussion on each result and achieve some new results. For the negative result, we prove that insufficiently secure obfuscator is the real cause of the negative result. We point out that the security of a white-box scheme cannot be guaranteed if it is instantiated by a less secure obfuscator, since the obfuscator used in their proof does not satisfy the "Virtual Black-box Property" with auxiliary input. From our proof,we also conclude that the notion WBP is equal to "Virtual Black-box Property with auxiliary input". For the positive result, we prove that security notion under black-box model should not be used in white-box context without any modification; although the positive result is meaningful, it is unlikely to prove that an obfuscator satisfies WBP for IND-CPA, since the security notion "IND-CPA" is under black-box model, which has different adversary with WBP.

Many organizations have insisted on protecting the cloud server from the outside,although the risks of attacking the cloud server are mostly from the inside.There are many algorithms designed to protect the cloud server from attacks that have been able to protect the cloud server attacks.Still,the attackers have designed even better mechanisms to break these security algorithms.Cloud cryptography is the best data protection algorithm that exchanges data between authentic users.In this article,one symmetric cryptography algorithm will be designed to secure cloud server data,used to send and receive cloud server data securely.A double encryption algorithm will be implemented to send data in a secure format.First,the XOR function will be applied to plain text,and then salt technique will be used.Finally,a reversing mechanism will be implemented on that data to provide more data security.To decrypt data,the cipher text will be reversed,salt will be removed,andXORwill be implemented.At the end of the paper,the proposed algorithm will be compared with other algorithms,and it will conclude how much better the existing algorithm is than other algorithms.

Internet of things(IoT)has become more popular due to the development and potential of smart technology aspects.Security concerns against IoT infrastructure,applications,and devices have grown along with the need for IoT technologies.Enhanced system security protocols are difficult due to the diverse capabilities of IoT devices and the dynamic,ever-changing environment,and simply applying basic security requirements is dangerous.Therefore,this proposed work designs a malware detection and prevention approach for secure data transmission among IoT gadgets.The malware detection approach is designed with the aid of a deep learning approach.The initial process is identifying attack nodes from normal nodes through a trust value using contextual features.After discovering attack nodes,these are considered for predicting different kinds of attacks present in the network,while some preprocessing and feature extraction strategies are applied for effective classification.The Deep LSTM classifier is applied for this malware detection approach.Once completed malware detection,prevention is performed with the help of the Improved Elliptic Curve cryptography(IECC)algorithm.A hybrid MA-BW optimization is adopted for selecting the optimal key during transmission.Python 3.8 software is used to test the performance of the proposed approach,and several existing techniques are considered to evaluate its performance.The proposed approach obtained 95%of accuracy,5%of error value and 92%of precision.In addition,the improved ECC algorithm is also compared with some existing algorithm which takes 6.02 s of execution time.Compared to the other methods,the proposed approach provides better security to IoT gadgets during data transmission.

Protecting the privacy of data in the multi-cloud is a crucial task.Data mining is a technique that protects the privacy of individual data while mining those data.The most significant task entails obtaining data from numerous remote databases.Mining algorithms can obtain sensitive information once the data is in the data warehouse.Many traditional algorithms/techniques promise to provide safe data transfer,storing,and retrieving over the cloud platform.These strategies are primarily concerned with protecting the privacy of user data.This study aims to present data mining with privacy protection(DMPP)using precise elliptic curve cryptography(PECC),which builds upon that algebraic elliptic curve infinitefields.This approach enables safe data exchange by utilizing a reliable data consolidation approach entirely reliant on rewritable data concealing techniques.Also,it outperforms data mining in terms of solid privacy procedures while maintaining the quality of the data.Average approximation error,computational cost,anonymizing time,and data loss are considered performance measures.The suggested approach is practical and applicable in real-world situations according to the experimentalfindings.

Quantum cryptography via Satellite

引用

Engineering 2019年第3期5卷 353-354页

作者： Mitch Leslie Senior Technology Writer

As it circled the Earth one night in 2017, the Chinese satellite Mozi, also called Micius, aimed a laser at a ground station in northeastern China (Fig. 1). Then, as it traveled toward Europe and into range, it directed a beam at a different receiver in Austria. These transmissions, delivered to sites 7600 km apart, were noteworthy because they marked the first time a satellite had relayed secret quantum keys for decrypting and viewing messages. With the keys, scientists in China and Austria were able to exchange and decipher encrypted images. And on 29 September 2017, the researchers used the system to set up an encrypted 75-minute video conference between members of the Chinese Academy of Sciences in Beijing and their counterparts at the Austrian Academy of Sciences in Vienna [1].

How to Integrate Abstract Algebra and Number Theory in the Teaching of Public Key cryptography Elegantly

引用

计算机教育 2018年第12期 136-137页

作者： Hu Xiong Ting Zhong Guobin Zhu Zhiguang Qin School of Information and Software Engineering University of Electronic Science and Technology of China

Different from traditional symmetric cryptography, public key cryptography allows each user to own a pair of public/private key pair. Given the public key of one user and the data to be encrypted, a ciphertext can be generated such that only the intended user is able to recover the data using his/her private key associated with public key involved in the encryption process. To really understand the philosophy behind the public key cryptography is not an easy task and sometimes it seems somewhat difficult, if not impossible, for the beginners without the knowledge of the abstract algebra and number theory. In this paper, we introduce briefly the basic definition of public key cryptography as well as the corresponding mathematical hard problems. Besides, we explain why the mathematical backgrounds, especially abstract algebra and number theory, matter in the study of public key cryptography.
