Cloud computing allows the users to store their data in its storage and use them whenever they need. While the data of user is traveling outside its physical infrastructure through Internet, it needs to use a very strong encryption to protect them against the hackers who attempt to steal or alter the data. Thus, the data security in transmission is so important. Most of the users send the data to cloud, but all the data do not have a high sensitivity. In this paper, K nearest neighbors algorithm is used to decide whether the data is normal sensitive or high sensitive, and then according to the level of sensitivity we proposed a framework to do data encryption. In order to ensure user authentication, we used one time password to authenticate the user, and for the data which belong to normal sensitivity level we have applied AES (advanced encryption standard)-192 algorithm. Finally, for the data which belong to high sensitivity level, AES-256 algorithm has been applied, and rsa (Rivest-Shamir-Adleman) algorithm is used to encrypt the key of AES 256, then we use hash-based massage authentication code to be attached in the end of message to ensure integrity and authenticity of message.

Knapsack based ECC for digital signature authentication

INTERNATIONAL JOURNAL OF COMMUNICATION NETWORKS AND DISTRIBUTED SYSTEMS 2009年第4期3卷 384-392页

Elliptic curve cryptography (ECC) provides a secure means of exchanging keys among communicating hosts using the Diffie Hellman key exchange algorithm. Encryption and decryption of texts and messages have also been attempted. This paper presents the ECC implementation for digital signature authentication and then applying the knapsack algorithm on ECC signing message. In this paper, we attempt to provide more secure digital signature scheme by using knapsack based ECC. We compare our proposed algorithm with rsa based digital signature authentication algorithm and show that our algorithm is better due to the high degree of sophistication and complexity involved. It is almost infeasible to attempt a brute force attack. Moreover, only one parameter namely the knapsack vector ai needs to be kept secret. On the contrary in rsa, three parameters such as the modulus n, its factors p and q need to be kept secret.

Comment on "An Enhanced and Secured rsa Key Generation Scheme (ESRKGS)"

引用

JOURNAL OF INFORMATION SECURITY AND APPLICATIONS 2016年 30卷 1-+页

作者： Luy, Erkam Karatas, Zekeriya Y. Ergin, Huseyin Erciyes Univ Kayseri Turkey Tuskegee Univ Tuskegee AL 36088 USA Univ Alabama Tuscaloosa AL USA

In this article, we do the cryptanalysis of the Enhanced and Secured rsa Key Generation Scheme (ESRKGS) given in Thangavel et al. (2015). The authors claimed that ESRKGS is a highly secure and not easily breakable scheme compared to the traditional rsa scheme. In their scheme, the public key n is a product of two large prime numbers, but the values of Encryption E and Decryption D keys are based on the product of four large prime numbers, N, which is a multiple of n. They claimed that even if someone factorizes n, in order to obtain the private key D, brute force must be used to obtain the other two primes. We prove that we can use an alternative private key D-1 to break the system. Someone does not need to employ brute force to break the system when n is factored. Hence, ESRKGS has the same security level as the traditional rsa. (C) 2016 Elsevier Ltd. All rights reserved.

Secure MIMO Visible Light Communication System Based on User's Location and Encryption

Visible light communication systems are rapidly growing research areas with wide applications ranging from illumination and data communication. To achieve high data rates in such systems, a number of techniques have been employed such as equalization of transmission signals, deployment of complex data modulation and the use of multiple input multiple output (MIMO) systems. However, security in wireless telecommunication systems is a common concern. This paper proposes a secure MIMO-VLC system that relies on the position of the user by incorporating a new modified version of the Rivest-Shamir-Adleman (rsa) technique for encrypting the transmitted data in the media access control MAC layer. The performance of the positioning method is evaluated showing a positioning accuracy of less than 5 cm for a signal-to-noise ratio of 15 dB. Furthermore, the ability of the proposed system to control the size of the encrypted cell, depending on the application environment, is demonstrated.

rsa algorithm is one of the most widely used public key encryption algorithm. Breaking rsa encryption is considered very difficult and is well-known as rsa problem. The difficulty of this problem lies in prime factorization of large integers. In this paper, we introduce the idea of factorizing large integers to break rsa encryption using weighted spiking neural P systems with rules on synapses. Moreover, parallelism of weighted spiking neural P systems with rules on synapses allows the system to perform a space-time trade-off, and it helps the system to factorize large integers in linear time.

MODERN DATA ENCRYPTION

引用

ELECTRONICS & COMMUNICATION ENGINEERING JOURNAL 1993年第5期5卷 271-278页

作者： BOYD, C Communications Research Group Electrical Engineering Laboratories University of Manchester Manchester UK

Communications security is increasing in importance as a result of the use of electronic communications in more and more business activities. Cryptography is the only practical means to provide security services in many applications. Research into cryptography has exploded in the last 18 years and a variety of cryptographic algorithms and techniques have emerged. Cryptographic algorithms may be classified as either symmetric, if the same key is shared by the sender and receiver, or asymmetric, if they use different keys. Symmetric algorithms have been dominated by the Data Encryption Standard since 1976, but a number of replacements are now being proposed. Asymmetric, or public key, algorithms allow provision of new security services such as digital signatures. The rsa algorithm is the most widely known of these, but a recently proposed standard for digital signatures is also of intense current interest.

This paper describes some properties of exponentiation modulo a polynomial and suggests its use for encryption in a mode that can be cryptanalyzed in approximatelyO(pd ³) time, whered is the size of the message frame andp is the prime modulo which the rankwise computations are carried out. While for sufficiently largepd (～10⁵) this appears to provide a one-way function which can be used in a public-key cryptosystem, we show that since encryption/ decryption effort is defined inO(d ² logpd log logp) time, a practical application of the proposed algorithm would be either in a secret key or in a tamper-proof, hardwired secret polynomial system.
