![]() Based on an example on a magic square of order 3 and the inverse of modular magic square some results are obtained. In this paper, a new method for constructing semi-magic squares depends on the proposition of the arithmetic modular together with the operations of addition, subtraction, multiplication, rotation, and reflection is introduced. The constructions of magic squares are discussed by many research using different approaches. Order magic square such that, each of its row, column and diagonals is summed to the same constant. Magic square is a rich source of mathematical properties that related with a great deal of branches of mathematics and its applications. The work can be considered significant in the field of encrypting databases because the repetition of encrypted data inside databases is considered an important vulnerability that helps to guess the plaintext from the encrypted text. The proposed technique is robust against disclosing the repetition encrypted data based on the result of Avalanche Effect in an accepted ratio (62%) and the results of the output of the proposed encryption method have acceptable randomness based on the results of the p-values (0.629515) of the National Institute of Standards and Technology (NIST) randomness tests. Where, all elements that uses were polynomial numbers of a finite field of degree Galois Fields GF (28). In the hiding stage, the ciphertext was hidden into a 16×16 matrix that includes 16 sub-magic squares to eliminate the duplicates in the ciphertext. Two techniques of encrypted and hiding were executed in the encryption stage by using a magic square size 3×3 and Latin square size 3x3 to providing more permutation and also to ensure an inverse matrix of decryption operation be available. Therefore, the proposed method was established to prevent the attackers from exploiting the vulnerabilities of the redundancy in the ciphertext and enhances the substitution and permutation operations of the encryption process the solution was performed by eliminates these duplicates by hiding the ciphertext into a submatrix 4x4 that chooses randomly from magic square 16x16 in each ciphering process. Which would not be possible without weakening the encryption that currently protects all messages.Hackers should be prevented from disclosing sensitive data when sent from one device to another over the network. ![]() It allows the government or regulator Ofcom to demand that apps scan messages for terrorist or child sexual abuse material. The Online Safety Bill, introduced by Boris Johnson, is currently on its way through parliament. But officials have argued that it should be weakened so that messages can be scanned for illegal content. It is necessary to protect messages from hacking and other threats. And even the services themselves do not have access. Which has said that it would absolutely, 100% leave the UK if it received such a request.Įnd-to-end encryption secures messages by ensuring that only those sending and receiving them can read them. This has brought criticism from not only WhatsApp but also rival secure messaging app Signal. If the UK government were to demand that WhatsApp weaken its encryption, Mr Cathcart confirmed that the company would refuse, leaving open the possibility that the app would be banned entirely within the country.
