SUPER ENKRIPSI ALGORITMA ROUTE CIPHER DAN ALGORITMA VARIABLY MODIFIED PERMUTATION COMPOSITION (VMPC) UNTUK PENGAMAN FILE CITRA

Securing image files is a crucial aspect in addressing information security challenges. Super encryption is an approach that combines various cryptographic algorithms to enhance data security. In this research, we implement Super Encryption by combining two algorithms, namely Route Cipher and VMPC (Variably Modified Permutation Composition). Firstly, we employ the Route Cipher to encrypt image files by rearranging the pixels in the image using a specific mapping scheme. Subsequently, we apply VMPC, a key-symmetric encryption algorithm, to encrypt the previously modified image. The use of VMPC as the second layer aims to provide additional security by incorporating efficient and secure key-symmetric encryption. The results of this research demonstrate that the combination of Route Cipher and VMPC provides strong security for image files. This method introduces a high level of complexity for attackers attempting to decrypt the image without the correct key. Moreover, this Super Encryption offers higher confidentiality and resilience against attacks on image files compared to using a single encryption algorithm.

A Layered Encryption Model PABB Based on User Privacy in E-commerce Platforms

In the era of big data, e-commerce platforms have increasingly strict requirements for encryption systems to prevent user privacy breaches. Traditional encryption systems use a single encryption algorithm, which cannot achieve a balance between efficiency and security. The layered encryption model PABB classifies and layers user data of different security levels, using targeted different encryption algorithms for protection, balancing the requirements of security and efficiency.

Comparative analysis of enhanced hybrid encryption algorithm with single encryption algorithm

To accomplish end users data security, it appears that the methods currently used to ensure data security, privacy, integrity, and availability to cloud users are insufficient. An encryption method will be required to guarantee the private preservation of users data while it is in transit or persistent state. The security of cloud data is ensured by a hybrid encryption algorithm that includes the use of the symmetric Advanced Encryption Standard (AES) and an asymmetric RSA algorithm ,combining an asymmetric algorithm (public-key cryptography, or PKC) with a symmetric algorithm (also called private key cryptography), which employs a single key for encryption and decryption, to increase the security of cloud data. Hybird encryption has significant benefits over single encryption in terms of security, speed and computation time. By first encrypting data with AES and then encrypting the AES key with RSA while in the cloud, the suggested method offers a hybrid encryption scheme that improves the security of cloud data. This paper examines various forms of cryptographic encryption and also offers a enchanced hybrid encryption technique for online applications.

Hadoop-based secure storage solution for big data in cloud computing environment

In order to address the problems of the single encryption algorithm, such as low encryption efficiency and unreliable metadata for static data storage of big data platforms in the cloud computing environment, we propose a Hadoop based big data secure storage scheme. Firstly, in order to disperse the NameNode service from a single server to multiple servers, we combine HDFS federation and HDFS high-availability mechanisms, and use the Zookeeper distributed coordination mechanism to coordinate each node to achieve dual-channel storage. Then, we improve the ECC encryption algorithm for the encryption of ordinary data, and adopt a homomorphic encryption algorithm to encrypt data that needs to be calculated. To accelerate the encryption, we adopt the dual-thread encryption mode. Finally, the HDFS control module is designed to combine the encryption algorithm with the storage model. Experimental results show that the proposed solution solves the problem of a single point of failure of metadata, performs well in terms of metadata reliability, and can realize the fault tolerance of the server. The improved encryption algorithm integrates the dual-channel storage mode, and the encryption storage efficiency improves by 27.6% on average.

DESIGN AND SIMULATION OF NEW AND FAST AUTHENTICATED ENCRYPTION ARCHITECTURE (AESSEA3)

Authenticated Encryption (AE) is a very important technique that ensures the security of data transportation. AE combines encryption and authentication to provide both privacy and authenticity of the data. In this paper, design, analysis and simulation of a fast and new Authenticated Encryption architecture called Authenticated Encryption SSEA3 (AESSEA3) is introduced on the basis of unpredictability concept. Unpredictability is a concept based on dynamic use of encryption algorithms, where instead of using single encryption algorithm for producing the ciphertext, multiple encryption algorithms are used in the same structure. Pseudo Random Number Generator (PRNG) is used to select which encryption algorithm will be used. Two double AES-256 are used with only 3 rounds to add the unpredictability concept which provide high speed and high security level. The plaintext enters one Double AES-256 and RC4 output enters the other Double AES-256. Also, the security increased by Xoring between the two outputs from the two algorithms to get the ciphertext. The proposed algorithm is faster than AGEIS which is one of the fastest AE algorithms. A new structure for AE is introduced to confirm authenticity. Tag partitioning concept is used. The proposed algorithm can resist different types ofcryptanalysis attacks.

Dynamically Changing the Symmetric Encryption Algorithm for Improving Security and Performance during Data Transfer in Grid Networks

In grid design authentication, authorization and confidentiality of the communication between computers are important security requirements. Without the functionality, the integrity and confidentiality of the data processed, the grid would be at risk. There are many different tools and technologies, which are available to ensure secured grid environment. The symmetric and asymmetric encryption algorithms are commonly used algorithms in grid software to provide necessary security, even though symmetric encryption algorithm significantly will affect the network communication performance. The previous work relied on the use of encryption and decryption at the application layer has an impact on the application layer performance and in the network layer performance. In the proposed work, instead of using a single encryption algorithm different encryption algorithms were selected arbitrarily during processing of each packet. The performance has been measured through simulation studies on NS2 by simulating these algorithms on GARUDA Grid Network Topology.
