Steganography Using Aes

International Journal of Advanced Trends in Computer Science and Engineering , 2021

The transmission of information through any channel of correspondence needs solid encryption procedures with the end goal of information security. The computerized watermarking assumes a significant part in inserting data into an advanced picture signal, for the check and character of its proprietors. In discrete wavelet change, "investigation channel bank" can be utilized for dissecting picture signals by going through. The channel bank comprises high and low pass channels at every deterioration stage. In this paper, a technique to consolidate steganography (Least Significant Method-LSM) and cryptography Advanced Encryption Standard (AES) is thought to give a safer method to information transmission through any unstable or public organizations. Prior to inserting the content in the picture, the text is scrambled utilizing AES calculation. Utilizing least significant bit (LSB) strategy, encoded the text installed in low-low (LL) subband wavelet decayed of a picture. Converse wavelet changes applied will lead to the output picture is communicated to the recipient. Presently at the collector's end, the picture changed utilizing wavelet and encoded text will be extricated by utilizing the LSB technique. This paper shows how AES calculation is utilized in the decoding of the outcome.

The rate at which encrypted messages are being sent over the internet and other electronic means will easily capture the attention of hackers and possibly make them try to disrupt or even hack those messages so as view the original message. Steganography is designed to hide the presence of a message by hiding the secret message inside an innocent file. For effective security, steganography is sometimes combined with cryptography. In this paper, steganography and cryptography are combined to provide a robust system capable of encrypting a secret message using RSA algorithm. To hide the message, advanced LSB method is used. The original message is encrypted at the initial stage and then separated into two portions P1 and P2. An XOR operation is applied to the first portion (P1) using the odd location and to the second portion (P2) using the even position of the LSB+1.The Position of the LSB is then used to hide the XORed encrypted message.

Steganography and Cryptography are two popular ways of sending vital information in a secret way. One hides the existence of the message and the other distorts the message itself. There are many cryptography techniques available; among them AES is one of the most powerful techniques. In Steganography we have various techniques in different domains like spatial domain, frequency domain etc. to hide the message. It is very difficult to detect hidden message in frequency domain and for this domain we use various transformations like DCT, FFT and Wavelets etc. In this project we are developing a system where we develop a new technique in which Cryptography and Steganography are used as integrated part along with newly developed enhanced security module. In Cryptography we are using AES algorithm to encrypt a message and a part of the message is hidden in DCT of an image; remaining part of the message is used to generate two secret keys which make this system highly secured.

Steganography is the technique of hiding information so that any intermediate third party is unaware about the presence of secret message. Digital steganography uses some digital media as the cover for the secret message, like in our case, we have used digital images as the cover media. Essence of steganography is that the third party should never be able to detect the presence of secret message in the cover image. Once the third party detects the secret message, it is assumed that the steganography technique has failed to serve its purpose. The proposed model presents a novel approach of develop a secure data hiding technique of Steganography using wavelet transform, Some logical operations, binary convertor, along with random number generation method.

As use of computer networks and internet is growing very fast and admiring day by day, information security is become a major concern in computer networks. There is always risk in violation of network security which leads a need of an efficient and simple way of securing the electronic documents from being read or used by people other than who are authorized to do it. Encryption is one of the security technique widely used to ensure secrecy. Encryption is an entirely mathematical process that takes in data, performs some predefined mathematical operations on the data, and then outputs the result. Blowfish is one of the superlative encryption algorithms because it requires less execution time, memory and has high throughput. However if any eavesdropper detects the presence of encrypted data he or she can try several attacks in order to get the original data. So there is a need to provide a two layer approach for better security. That's why this work presents a security system using combination of cryptography and steganography to enhance the security.

The two important aspects of security that deal with transmitting information or data over some medium like Internet are steganography and cryptography. Steganography deals with hiding the presence of a message and cryptography deals with hiding the contents of a message. Both of them are used to ensure security. But none of them can simply fulfill the basic requirements of security i.e. the features such as robustness, undetectability and capacity etc. So a new method based on the combination of both cryptography and steganography known as Crypto-Steganography which overcome each other's weaknesses and make difficult for the intruders to attack or steal sensitive information is being proposed. This paper also describes the basics concepts of steganography and cryptography on the basis of previous literatures available on the topic.

In the cryptographic steganography system, the message will first be converted into unreadable cipher and then this cipher will be embedded into an image file. Hence this type of system will provide more security by achieving both data encoding as well as data hiding. In this paper we propose an advanced steganocryptic system that combines the features of cryptography and steganography. In this proposed steganocryptic system we will encrypt the message into cipher1 by using Kunal Secure Astro-Encryption and we again encrypt this cipher to cipher2 by using grid cipher technique. Advantage of Kunal Secure Astro-Encryption is that it generates random useless points in between, thus fixed size messages can be generated providing more security compared to other cryptographic algorithms as the number of characters in original message cannot be found from encrypted message without the knowing the black holes. Now we will embed this cipher2 into image file by using visual steganography .In this proposed steganocryptic system we will use modified bit insertion technique to achieve visual steganography. This proposed system will be more secure than cryptography or steganography techniques[digital steganography] alone and also as compared to steganography and cryptography combined systems.

Encryption system is the mechanism of protecting secrets by applying mathematical functions to original text to produce cipher text that is difficult to decrypt. In this paper, an encryption mechanism is presented which is the combination of cryptography and steganography technology. On the proposed system cryptography algorithm is chosen for encrypt plaintext by applying mathematical function. On the other hand steganographic algorithm is used for hiding the encrypted data into an image that no one can see the secret information. LSB (Least Significant Bit) method is used on the steganography part for hiding information into an image. Four keys are needed for decryption the information.

The need for security in data communication is as long as mankind; since eavesdroppers often intercept such communication for malicious purposes. Several techniques such as steganography and cryptography have been employed to hide the existence of communication and scramble such communication making it difficult to interpret in cases where steganography fails. Combining Cryptography and steganography has proven to have taken data communication security to another level. In this work, a review of these techniques is presented with major focus on two journals titled " Dual Layer Security of Data Using LSB Image Steganography Method and AES Encryption Algorithm " [1] and " An Efficient Data Hiding Scheme Using Steganography and Cryptography Technique " [2]were considered for review. A brief description of the techniques is provided. It is found that these techniques could improve security of data communication beyond the present levels if properly combined with little or no performance degradation.

In this paper we hide the message (data), using the concept of Steganography; in such a way that on-one apart from the sender and intended recipient even realizes there is a hidden message. The proposed method hides the secret message based on searching about the identical bits between the secret messages and image pixels values. The new approach is based on the LSB (Least Significant Bit) method. Also a new approach is proposed to securely sending the message using Cryptographic concept in Steganography. From the sender side the encrypted message is send and hides it in a saved picture and encodes the message. At the receiver side decryption is done to get original message.

A new technique proposed with the combination of cryptography and steganography enhanced with new secure feature for generating a new security system. Cryptography and Steganography are two popular ways for secure data transmission in which the former distorts a message so it cannot be understood and another hides a message so it cannot be seen. In cryptography, this system is used advanced encryption standard (AES) algorithm to encrypt secret message and then these are separated keys; one of which is used to hide in cover image. In steganography, a part of encrypted message as a key is used to hide in discrete cosine transform (DCT) of an image which is highly secured. This kind of system is to be introduced in applications such as transferring secret data that can be authentication of various fields.

Information security is becoming more important and attracting much attention nowadays, as the amount of data being exchanged over the internet increased. There are various techniques to secure data communication, but the well-known and widely used techniques are cryptography and steganography. Cryptography changes data into another form that is unreadable by anyone except the intended receiver. Steganography hides the existence of secret data in a cover medium, so that no one can detect the hidden data except the authorized receiver. In this paper, we proposed a new technique for securing data communication systems by combining cryptography and steganography techniques. The cryptography algorithm that was used in this paper is Modified Jamal Encryption Algorithm (MJEA); it is a symmetric (64-bit) block encryption algorithm with (120-bit) key. For steganography, we designed an enhanced form of Least Significant Bit (LSB) algorithm with (128-bit) steg-key. The performance of the proposed technique has been evaluated by considering several experimental tests, such as impressibility test, embedding capacity test and security test. For this purpose, the proposed technique was applied on several 24-bit colored PNG cover images. All experimental results proved the strength of the proposed algorithm in securing the transition of data over unsecure channels to protect it against any attack. Furthermore, the simulation results show the superiority of our proposed algorithm when compared with other algorithms in terms of PSNR and embedding capacity.

The art of concealing / hiding information or data bits on a cover or carrier file is known as Steganography. We can envisage Steganography being utilized in nearly any sort of file, including image files. Masking information, such as text, photos, or audio files, within other image files is known as Image Steganography. Image steganography enables the communication between one another, secretly and stealthily. To add even more security, the secret message, which is contained within the image file, is encrypted. Data compression is an important aspect of information security since compressed data is more secure and easier to manage. By encrypting data and hiding it from attackers, the primary purpose is to save physical space on storage devices and reduce the time it takes to transport data over the internet. The secret message is then coded and compressed before being combined into the compressed cover image file. The result stego-image is then sent to the receptor where the message is uncompressed, decoded and retrieved. This survey focuses on the methods implemented by authors of several works for hiding and securing the information.
