Deniable encryption

Abstract Introduction to Encryption Encryption is the process of encoding information in such a way that only the person (or computer) with the key can decode it. Encryption is a way to enhance the security of a message or file by scrambling the contents so that it can be read only by someone who has the right encryption key to unscramble it. Encryption has widely been used to protect data in numerous areas, such as e-commerce, online banking, cloud storage, online communication and so forth. For

A research project that synthesizes your knowledge of encryption, keys, and virtual private networks. Write a 5-7 page report on your findings. Encryption Encryption refers to a technique that facilitate the storage, transmission of information in a format that is unreadable to unintended audience. Unintended audience in this case may be hackers, sniffers, malwares e.t.c.the technique has been widely used to curb phishing in the current network security landscape. There are two fundamental techniques

first effort of searching encrypted data by keyword was tackled by Song, Wagner and Perrig cite{s1}. To securely search over encrypted data, searchable encryption schemes have been proposed in recent years cite{b2,b3,b5,c2,c4,g1,w2}, which can be divided into two schemes: symmetric searchable encryption (SSE) and asymmetric searchable encryption (ASE). To perform a search on a dataset, an user creates an index of keywords listed in the documents and later on executes the search on the index in a

encrypt their body using a specified encryption algorithm but using different keys at every infection. Each encrypted virus has a decryption routine that usually remains the same, despite the fact that the keys change between infections. Therefore, it is possible to detect this class of viruses by analyzing the decryptor in order to obtain a reasonable signature. Figure 1 shows an encrypted virus example. Encrypted viruses tend to use simple algorithms for encryption. Common variants use algorithms such

aspects of electrical engineering and computer science. In this chapter, our main focus is encryption of JPEG2000 compatible images. Though both stream and block cipher have been investigated in the literature, but this chapter provides a detailed study of block cipher as applied to images, since JPEG2000 generates various subband sizes as blocks. In the first section, we briefly define various encryption components like wavelet transform, bit plane decomposition, XOR operation, artificial neural

Confidentiality opt to keep big data secret in cloud computing for unauthorized access, in our model we are willing to keep data secret even from the cloud service provider, therefore we propose to encrypt data before send it to the cloud, the encryption method is discussed below. Integrity prevents any kind of alter (modify or delete) or fabricate of sensitive information by unauthorized persons, integrity is related to confidentiality because by preventing unauthorized access to big data we can

Background Cryptography is known as the method of writing secrets. The secured data and all of information from any external or internal hacks. Therefore, it provides confidentiality, integrity, authenticity and non-repudiation to secure data. The basic concepts of cryptography will be based on two terms namely plain text and cipher text. Plain text represents the message generated originally and cipher text is the message which is the encrypted text. We would decrypt the encrypted cipher text to

The paper proposes data hiding with codeword substitution in encrypted H.264/AVC video streams. Here video is encrypted and data is hided in the video to maintain the security and privacy. In this way data hiding in encrypted domain without decryption preserves confidentiality of the content. By analyzing the property of H.264/AVC codec, the codeword of the intra-prediction modes, the code words of motion vector differences and code words of residual coefficients are encrypted with the stream ciphers

hided in image due to which only less amount of data was made secure if the large amount of data is hided in the image then the image gets blur. 2. In previous project the AES algorithm was used for encrypting the data which required more time for encryption. 3. Only single level security was provided to the data while transmission of data. 4. PROJECT OBJECTIVE 1. In our project we are using video due to which large amount of data can be transmitted securely. 2. In our project we are using Blow fish

Abstract— Encryption is widely used to ensure security in data storage and communication systems. This paper introduces a new concept for image encryption using a new method we named it "Meaning Of Location (MOL)". In this method, the private key is an image that converted into RGB numbers and the public key is random integers used to permutate the image. The location of the RGB will be used to encrypt the plaintext. The performance of this algorithm is investigated against many different attacks
