Overcoming Problems Combination of Server and Client Side Encryption on Web Code Security Using the Slice Code Method

Web security protection that is carried out by some web developers is to protect the source code of web applications by encrypting the source code, both the source code that runs on the web server or the source code that runs on the client browser. Combining these two encryption technologies is a problem for web developers. If using server side encryption, the client side source code is not protected. However, if you use client-side encryption, the server source code becomes unreadable by the web server. This study aims to overcome the problem of the combination of these two encryption technologies, so the Slice Code method is used, which is a method that the researchers themselves have developed and used to encrypt server and client source code simultaneously and combine the two. With this method, the original source code is separated into 2 parts, then the pure client source code is encrypted using client encryption technology, then embedded into the pure server source code. The next step is to encrypt the pure server source code. The result is that web applications can run perfectly by having source code encryption from both sides, namely the server side and the client side.

Hybrid Encryption Scheme for Medical Imaging Using AutoEncoder and Advanced Encryption Standard

Recently, medical image encryption has gained special attention due to the nature and sensitivity of medical data and the lack of effective image encryption using innovative encryption techniques. Several encryption schemes have been recommended and developed in an attempt to improve medical image encryption. The majority of these studies rely on conventional encryption techniques. However, such improvements have come with increased computational complexity and slower processing for encryption and decryption processes. Alternatively, the engagement of intelligent models such as deep learning along with encryption schemes exhibited more effective outcomes, especially when used with digital images. This paper aims to reduce and change the transferred data between interested parties and overcome the problem of building negative conclusions from encrypted medical images. In order to do so, the target was to transfer from the domain of encrypting an image to encrypting features of an image, which are extracted as float number values. Therefore, we propose a deep learning-based image encryption scheme using the autoencoder (AE) technique and the advanced encryption standard (AES). Specifically, the proposed encryption scheme is supposed to encrypt the digest of the medical image prepared by the encoder from the autoencoder model on the encryption side. On the decryption side, the analogous decoder from the auto-decoder is used after decrypting the carried data. The autoencoder was used to enhance the quality of corrupted medical images with different types of noise. In addition, we investigated the scores of structure similarity (SSIM) and mean square error (MSE) for the proposed model by applying four different types of noise: salt and pepper, speckle, Poisson, and Gaussian. It has been noticed that for all types of noise added, the decoder reduced this noise in the resulting images. Finally, the performance evaluation demonstrated that our proposed system improved the encryption/decryption overhead by 50–75% over other existing models.

Comparative Study of Cryptography for Cloud Computing for Data Security

Background: Cloud computing is an emerging technique by which anyone can access the applications as utilities over the internet. Cloud computing is the technology which comprises of all the characteristics of the technologies like distributed computing, grid computing, and ubiquitous computing. Cloud computing allows everyone to create, to configure as well as to customize the business applications online. So the cloud computing techniques need security of information communicated between the sending and receiving entities. Objective: The secure data storage disadvantage of Cloud computing can be resolve up to some extent with the help of the implementation of the cryptographic algorithms during the storing and accessing of the data from the cloud servers. Method: In this paper we have compared four different recently implemented Cryptographic Algorithms which are Modified RSA (SRNN), Elliptic Curve Cryptography Algorithm, Client Side Encryption Technique and Hybrid Encryption Technique. Conclusion: Client Side Encryption Technique and Hybrid Encryption Technique are better than Modified RSA and Elliptic Curve Cryptography because Client Side Encryption Technique has an advantage that in this data is encrypted prior to upload the data on the cloud i.e. encryption at the client side which provides an additional layer of security to the data on the cloud. On the other hand, Hybrid Encryption Technique has an advantage that it uses the rapidity of the processing time of Symmetric Key Cryptography and robustness in key length of the Asymmetric Key Cryptography.

Square chain offers a creative way to deal with putting away data, executing exchanges, performing capacities, and building up trust in an open situation. Many consider the square chain as an innovative leap forward for cryptography and digital security. Square chain administrations incorporate verification, secrecy, security and access control list (ACL), information and asset provenance, and uprightness affirmation. Every one of these administrations is basic for the current appropriated applications, particularly because of the huge measure of information being handled over the systems and the utilization of distributed computing. Square chain method is furnished with validation, inspecting, and responsibility, and consequently, it can fill in as a promising instrument for giving secure information correspondence on the system. Validation guarantees that the client is who he/she professes to be. Privacy ensures that information can't be perused by unapproved clients. Protection gives the clients the capacity to control who can get to their information. Provenance permits an effective following of the information and assets alongside their proprietorship and usage over the system. Trustworthiness helps in checking that the information has not been changed or adjusted. These administrations are right now overseen by concentrated controllers, for instance, a declaration authority. Along these lines, the administrations are inclined to assaults on the incorporated controller. Then again, the square chain is made sure about and disseminated records that can help settle a large number of the issues with centralization. From a security viewpoint, the square chain is made and kept up utilizing a distributed overlay arrangement and made sure about through shrewd and decentralized use of cryptography with swarm processing. Block chain offers an imaginative way to deal with putting away data, executing exchanges, performing capacities, and setting up a trust in an open environment. Many consider the square chain as an innovative leap forward for cryptography and digital security, with use cases running from internationally conveyed digital money frameworks. A decentralized distributed storage arranges has been presented with numerous favorable circumstances over the server farm based capacity. Comparable to conventional arrangement, decentralized distributed storage organize use customer side encryption to keep up information security.

Secured Cloud Data Transmission using Cross ABE Algorithm

Cloud security is becoming more essential than ever with the tremendous development of delicate cloud data. The cloud information and services are located in massively scalable data centers and can be accessed anywhere. Unfortunately, the development of cloud users has been followed by an increase in cloud malicious activity. More and more vulnerabilities are being found, and fresh safety advisories are being released almost every day. Millions of customers surf the cloud for different reasons, so they need extremely secure and persistent services. The cloud storage system interconnect with the a load of potential security risks. So the cross encryption of Ciphertext Policy Attribute Based Encryption (CPAB) and Key Policy Attribute-based encryption algorithm which increases the security level in the encryption side. A segmentation part helps in splitting the encrypted file in storing the data in the cloud side, the Desegmentation part in the receiver side can easily combines spitted data into the single file for validation examine an authentication level in the received data. Here the cloud storage easily with the file fragmentation processes. This processes research over the storing mass amount of data on off- site installation, which can eliminate the cost in maintaining the physical hardware. Cloud's future includes a much greater degree of privacy and authentication, particularly in extending the variety of apps. We suggest a straightforward data protection model where data is encrypted before it is introduced in the cloud using key policy attribute-based encryption to ensure data confidentiality and safety. The storing data is the most common application for the cloud server.

Encryption to Decryption Statistics for Secure Data with Independent Servers for Deduplication

Encoding information on the customer side before transferring it to distributed storage is fundamental for ensuring clients’ protection. Anyway customer side encryption is inconsistent with the standard routine with regards to deduplication in distributed storage administrations. Deduplication of records on the capacity servers has been very much clarified on different arrangements which utilized autonomous servers. An answer has been proposed considering customer side encryption and server side deduplication and guaranteeing security while utilizing a solitary server for the entire procedure. This arrangement was tended to at record level and had the thought to actualize square level deduplication utilizing a similar deduplication convention. We examined the odds of executing square level deduplication considering the single server record level deduplication plan of the base convention. We executed and examined this situation and played out an unpleasant examination with the record level deduplication by recreation. Both the plans appeared to be similar. We exhibit that our plan gives preferable security ensures over past efforts. We present the main secure cross-client deduplication plot that supports customer side encryption without requiring any extra autonomous servers. Curiously, the plan depends on utilizing a PAKE (secret word confirmed key trade) convention.

A framework for critical security factors that influence the decision of cloud adoption by Saudi government agencies

Cloud computing technologies can play an essential role in public organisations and companies while it reduces the cost of using information technology services. It allows users to access the service anytime and anywhere, with paying for what they use. In developing countries, such as Saudi Arabia, the cloud computing is still not extensively adopted, compared to countries in the west. In order to encourage the adoption of cloud services, it is considerable to understand an important and particular complications regarding to cloud computing is the potential and perceived security risks and benefits posed by implementing such technology.This paper investigates the critical security factors that influence the decision to adopt cloud computing by Saudi government agencies. A framework was proposed for three categories, Social Factors category, Cloud Security Risks Category and Perceived Cloud Security Benefits that includes well-known cloud security features. The framework factors were identified by critically reviewing studies found in the literature together with factors from the industrial standards within the context of Saudi Arabia. An experiment study was conducted in five government agencies in Saudi Arabia by interview and questionnaire with experts in order to improve and confirm the framework. All the factors in the proposed framework were found to be statistically significant. An additional factor identified was Failure of client side encryption. Moreover, they suggested including this factor as a potential risk under Security Risk Factors Category. The initial framework was updated based on the expert reviews and questionnaires. The results were analysed via one-sample t-test with the data integrity analysed via Cronbach’s alpha. The outcome indicated the majority of cloud security adoption framework categories were statistically significant. Potential future study directions and contributions are discussed.

NEURAL NETWORK-BASED DOUBLE ENCRYPTION FOR JPEG2000 IMAGES

The JPEG2000 is the more efficient next generation coding standard than the current JPEG standard. It can code files witless visual loss, and the file format is less likely to be affected by system file or bit errors. On the encryption side, the current 128-bit image encryption schemes are reported to be vulnerable to brute force. So there is a need for stronger schemes that not only utilize the efficient coding structure of the JPEG2000, but also apply stronger encryption with better key management. This research investigated a two-layer 256-bit encryption technique proposed for the JPEG2000 compatible images. In the first step, the technique used a multilayer neural network with a 128-bit key to generate single layer encrypted sequences. The second step used a cellular neural network with a different 128-bit key to finally generate a two-layer encrypted image. The projected advantages were compatible with the JPEG2000, 256-bit long key, managing each 128-bit key at separate physical locations, and flexible to opt for a single or a two-layer encryption. In order to test the proposed encryption technique for robustness, randomness tests on random sequences, correlation and histogram tests on encrypted images were conducted. The results show that random sequences pass the NIST statistical tests and the 0/1 balancedness test; the bit sequences are decorrelated, and the histogram of the resulting encrypted images is fairly uniform with the statistical properties of those of the white noise.

A Developed Discrete Fourier Transform based Cryptosystem

This paper provides a developed cryptosystem for data encryption based on using the Discrete Fourier Transform (DFT). The encryption side using the DFT method for performing the main security development that is considered as the main encryption process in the developed cryptosystem. The primary ciphered plaintext data must be prepared as a block of (N) data, and entered to the DFT part. The decryption side uses as an inverse DFT method, to get back the primary ciphered plaintext from the received cipher text. The proposed method applied to classical encryption method, and can be applied to a stream cipher method. The validity of the developed encryption process is illustrated through many numerical examples.

A New Sender-Side Public-Key Deniable Encryption Scheme with Fast Decryption

Deniable encryption, introduced in 1997 by Canetti, Dwork, Naor, and Ostrovsky, guarantees that the sender or the receiver of a secret message is able to “fake” the message encrypted in a specific ciphertext in the presence of a coercing adversary, without the adversary detecting that he was not given the real message. Sender - side deniable encryption scheme is considered to be one of the classification of deniable encryption technique which defined as resilient against coercing the sender. M. H. Ibrahim presented a sender ? side deniable encryption scheme which based on public key and uncertainty of Jacobi Symbol [6]. This scheme has several problems; (1) it can’t be able to derive the fake message M f that belongs to a valid message set, (2) it is not secure against Quadratic Residue Problem (QRP), and (3) the decryption process is very slow because it is based dramatically on square root computation until reach the message as a Quadratic Non Residue (QNR). The first problem is solved by J. Howlader and S. Basu’s scheme [7]; they presented a sender side encryption scheme that allows the sender to present a fake message M f from a valid message set, but it still suffers from the last two mentioned problems. In this paper we present a new sender-side deniable public-key encryption scheme with fast decryption by which the sender is able to lie about the encrypted message to a coercer and hence escape coercion. While the receiver is able to decrypt for the true message, the sender has the ability to open a fake message of his choice to the coercer which, when verified, gives the same ciphertext as the true message. Compared with both Ibrahim’s scheme and J. Howlader and S. Basu’s scheme, our scheme enjoys nice two features which solved the mentioned problems: (1) It is semantically secure against Quadratic Residue Problem; (2) It is as fast, in the decryption process, as other schemes. Finally, applying the proposed deniable encryption, we originally give a coercion resistant internet voting model without physical assumptions.
