An Effective Method For Encryption

Public and private key is an encryption technique used to secure data. Explain the operation and use of any encryption technique from the list below.

With the rapid development of computer technologies and internet, one can get any information through internet very easily. To transfer or convey a message from one point to another is also very convenient in today’s era. People who have internet and computer can get any type of information related to any field without any difficulty [1]. While transferring or communicating on internet safety and security remains an issue. Steganography schemes are used to get rid of these type of safety and security issues. The standard phrase “What You See Is What You Get (WYSIWYG)” is not true if the misuse or hacking is there. One can transfer secret information through internet using Steganography

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

being attacked, encrypt it with a secret key to obtain an encrypted bit stream . For that AES encryption is used. After AES encryption, will embed at the fourth bit position of . Some related information about the mosaic image generation process into the mosaic image for use in the secret image recovery process are also embed at the last fourth bit position of . Such information, described as a bit stream I like M, includes the following data items: 1) encryption key; and 2) total length of before encryption. After all this process Target image with mosaic image, residual value and all information that required to recover original image are transmitted to receiver

M2 – Explain the operation and use of encryption technique in ensuring security of transmitted information

Utilising cryptography to secure medical images and prevent both tampering and the re-identification requires a two step process involving the insertion of cryptographic algorithms and watermarking onto the image, this is able to completed without amending or hindering the pixel quality and retaining the integrity of the images (Kester et al., 2015). Additionally, the watermark can be encrypted using an advanced encryptions standard (AES) to assist in maintaining patient privacy from being re-identified (Abd-Eldayem,

Multimedia content is also in collaboration with Encryption & Decryption standards (CBR).The below paper is the general

Information security is a major concept in today’s industrial and computer era, so security must be higher to protect the confidential data. Information security plays major role in computer and network security with the use of different cryptography algorithms that includes the encryption and decryption of data with the uses of the algorithm and the key. By means of text or numerical key for the encryption can be dangerous because with the several hack attacks that a key can be broken. So I have proposed a new mechanism that will replace the text key with the image pixels and can gain high security which cannot be easy to break without prior knowledge.

These algorithms have their own positives and negatives. New algorithms are evolving day by day. Two algorithms listed below are discussed in this essay.

There are many aspects to security and applications, from secure commerce and payment to private communications and protecting passwords. Cryptography, is the practice and study in securing communication between parties in the presence of potential adversaries (Yousuf, N.D.). This report focuses on modern methods of cryptography its operation, strengths and weaknesses, its application techniques in computing and some other aspects where cryptography deemed essential as discussed in this report.

In asymmetric encryption the public key can be distrusted to anybody while the private key which is kept by an individual. In order for this process to work, it is imperative that the two keys are mathematically paired in order to be able to encrypt and decrypt messages. Because they are mathematically paired, asymmetric encryption can work in both directions, where a message can be encrypted and decrypted with a public or private key, and encrypted and decrypted by the corresponding key. There are several disadvantages to using asymmetric encryption, some of which include that it is slow compared to symmetric encryption and the loss of the private key is an irreversible and unreplaceable action. Despite these disadvantages, the advantages of asymmetric encryption are its convenience in providing a solution for the distribution of the key found in symmetric encryption, and the combination of public and private keys provides us a method of authentication as private keys are needed in order to read the

Voice encryption system in wireless communication became very important. The advancement of modern wireless telecommunication and multimedia technologies makes a huge amount of sensitivity voice information travel over the open and shared networks. Voice based communication becomes prominent in the application areas of military, voice over IP, e learning, voice-conferencing, telephone banking, telephone services of market securities, etc. These applications are critical broadcast regarding the protection of data integrity and authorized user privacy.

We have also analyzed that without making motion vectors encryption, we can’t get temporal redundancy. Motion vector encryptions are proposed by many authors [4-9]. However, analysis shown in this paper said that 45-50% of motion vectors for each frame are not encrypted. Thus, better encryption method is proposed at here in expense with compression bandwidth. Overall, we have to make the balance between security and increase in compression bandwidth.

part uses random sequences generated from chaos system with the help of an encryption key. This key is then used to encrypt media contents with a neural network structure. However, the apparent disadvantage in this scheme is that more sub-keys need to be transmitted to the receiver. In another research [45], the authors propose an image encryption/decryption algorithm based on chaotic neural network. The employed network comprises two layers each with three layers: chaotic neuron layer (CNL) and permutation neuron layer (PNL). The approach uses a 160-bit-long authentication code to generate initial conditions and the parameters of both layers. The overall process is repeated several times to make it robust and increasingly complex. The proposed method uses two more keys where a slight mismatch in one of them fails in successfully decrypting an image. The authors in [46] propose an encryption method based on a hybrid chaos-based encryption algorithm. The algorithm employs permutation–diffusion architecture that uses chaotic control parameters for permutation. These control parameters for the permutation stage are generated by a logistic map. In the diffusion stage, another chaotic logistic map with different initial conditions and parameters is used to generate initial conditions for a hyper-chaotic Hopfield neural network to generate a key stream for image homogenization of the shuffled image. In order to provide summarized view, the authors in [47] present survey of
