Deniable encryption

The Counterfeit Coins Problem is a well-known complex search problem in mathematics as well as in computer science. It can be related to the data structure (such as binary tree) computer program, algorithm, Graph Theory, Therefore researching this problem is meaningful. The Counterfeit Coins problem can be described as given a set of n look-alike Coins containing One Counterfeit which is a bit heavier or lighter than the genuine Coins. The objective is to find the Counterfeit Coins in minimum…

Alan Turing was born June 23rd, 1912. He was the son of Julius Mathison and Ethel Sara Turing. He had an older brother, John Turing. John and Alan did not see their parents much because of their work. Turing was very smart, especially in science. He invented many machines that have helped us get to our point in technology. He saved millions of lives, changing the future forever. Alan Turing has done some major accomplishments in his life. He was not only a mathematician but also a cryptographer…

or secrete to the attacker. 21.6 To perform encryption and decryption using RSA algorithm: 1. Select two prime numbers: p and q 2. Calculate for n where n = pq 3. Calculate for the function of n where f(n) = (p-1)(q-1) 4. Select a letter e that is relatively prime to the function of n 5. Find d where de mode function of n and then correct the d got. 21.9 Majority of standards and products use public-key cryptography for digital signatures and encryption. The bits for RSA has increased in length…

provider that will help DO to perform a keyword search by calling BuildIndex(D,WDi,CP,DOpr). Each document Di comprising of an unique identifier IDi ∈ {0,1}n. Firstly, to protect the docu- ment Identifiers IDi, DO encrypts this IDiwith El Gamal encryption technique, such technique assurances that if the same document identifier is encrypted multiple times, it will create different ciphertexts but all decrypted to the same value. Then DO creates one Bloom filter BF for each document, this filter…

Steganography, or data hiding is the technique of embedding a message (pay¬load) in a medium (carrier), without causing suspicion about the existence of hidden data in the medium. The perturbations to the medium are carried out in such a manner that there is no perceivable noise component introduced. One way to illustrate the concept of steganography would be to analyze the Sim¬mons’ Prisoners’ problem. Two prisoners are allowed to communicate through a medium via an agent trusted by the warden.…

THE USEA 2.1. Data Encryption phase USEA encrypts 512-bit blocks of plaintext to cipher text by a 256-bit main key that from now we call it MK. In default, USEA consists of 20 identical rounds, but we can increase or decrease the rounds for amplification of our algorithm in specific hardware or software implementation. Note that Decreasing rounds of algorithm reduces its security against attacks. USEA uses different algebratic, logic and arithmetic operations for data encryption and decryption.…

IV Methodology The AES algorithm has 4 phases that execute the process in sequential manner. The encryption process is achieved by processing plain text and key for initial and 9 rounds, Same decryption is takes place but in reverse manner. A 4x4 state is formed in each round and particular length data is introduced in it for encryption process.The 10, 12, 14 rounds are there for 128, 192,256 bits in length respectively. Initially a key expansion process is used to expand the basic 16 byte key…

Abstract— the focus in this paper is on the symmetric encryption. There are some basic information about this type of cryptography will be reviewed. Then, symmetric cryptography advantages and problems will be covered. After that, comparison on several symmetric algorithms are discussed. These algorithms are DES, Triple DES, AES, RC2, RC4, RC6, and Blowfish. Keywords—Cryptography, Symmetric Encryption, Encryption, Decryption, DES, Triple DES, AES, RC2, RC4, RC6, Blowfish. I. INTRODUCTION…

misconception about the encryption that is required to be removed through focusing over the research and the latest findings in the relevant field of interest. Most of the organization believed that the data needs to be decrypted especially in the case when it is being used on mobiles. David was also having the similar views. He also explored the concerns of the organizations regarding the data being stolen from the The role of the third party in the process of encryption is also necessary to be…
