A new hybrid encryption and steganography technique: a survey

The improved technology in information security, now day has been being still developed. This, cause of the object called data which still has an important role in communications. There are two kinds of security technique, they are called steganography and cryptography. This paper will discuss growth of steganography technique from 2015 to 2019. The data obtained from journals and identified as a systematic literature review. The results are that improvement in steganography still developed by modifying the algorithm, combining the method and threating at parallel processing. Future, utilization of steganography is still needed, considered that communication channels are growing fast and sophisticated.

Steganography is used for invisible secured communication. In this technique, information is hidden on different medium like audio, video, text, or images by using different approaches or algorithms. This research has developed a novel steganography technique which combines grayscale image segmentation and least significant bit (LSB) substitution methods to hide information. In the proposed technique the cover image is segmented in a different number of blocks. Each block hides just one bit of information in its LSB. The number of blocks is directly proportional to the size of the information in bits. In such a way, information is hidden in the whole image, not in a specific area of an image, so there is no image degradation.

“…Encryption is the process of using an algorithm, called a cryptography algorithm, to convert plain text into an incomprehensible code and later convert it back to plain text [4] . The text relies mainly on the use of a numerical value, called the key, which is part of the encryption algorithm [4] . In [5] , encryption science is attributed to Arabs and is defined as the conversion of ordinary text to text not understood by those who do not know the particular encryption method used; i.e., only a person familiar with the encryption method and its rules would understand it.…”

“…The encryption algorithm is selected randomly by means of generating a number from 1-4. The numbers represent five types of encryption algorithm: AES (1), DES (2), 3DES (3), and Blowfish (4). Once the data are encrypted using one of the random algorithms, a table is populated with information about the file (i.e., file owner, file number, and algorithm used for encryption) and is stored as background information to be used in decryption and defragmentation in the final layer.…”

Most companies are sceptical about the security and insurance measures offered by cloud services and are reluctant to store sensitive data, such as employee records, in the cloud. Thus, more effort is needed to support the security of information in cloud computing. This paper proposes a cryptography algorithm called ―random algorithm‖ because it is built on the idea of randomising the encryption of uploaded files among four encryption algorithms. The proposed fragmentation technique helps add security and privacy to cloud storage applications. Based on earlier studies, we have created a file-level fragmentation technique that does not work at the database level, in contrast to commonly employed approaches in the case of fragmentation techniques such as horizontal fragmentation, vertical fragmentation, and hybrid fragmentation, which do work at the database level. The proposed encryption algorithm and fragmentation technique work within an integrated security framework that includes a user authentication gateway that encrypts user registration data through a cryptography algorithm called the RivestShamir-Adleman algorithm (RSA). The results of the proposed security framework were positive, as it contributed to reducing the encryption time and decoding time by approximately 99%, compared to earlier studies
