The proposed hybrid message embedded scheme consists of hill cipher combined with message embedded chaotic scheme. Hybrid Message-Embedded Cipher Using Logistic Map The problem of key management is discussed and circuits for the encryption and the decryption are suggested The novel algorithm can prevent a quantum attack strategy as well as a classical attack strategy. The other key is generated by the quantum shift register and used for the coding of the encryption message, where Alice and Bob share the key by using the BB84 protocol. One of them is the classical key that is used in the Hill cipher algorithm where Alice and Bob use the authenticated Diffie Hellman key exchange algorithm using the concept of digital signature for the authentication of the two communicating parties and so eliminate the man-in-the-middle attack. It is shown that, in the quantum block cryptographic algorithm, two keys can be used. The security of this algorithm is analysed in detail. The message is encoded and decoded by using a code generated by the quantum shift register. Khalaf, Rifaat Zaidan Abdullah, Alharith Abdulkareemīased on a quantum shift register, a novel quantum block cryptographic algorithm that can be used to encrypt classical messages is proposed. International Nuclear Information System (INIS) Novel Quantum Encryption Algorithm Based on Multiqubit Quantum Shift Register and Hill Cipher The result of the combination of these three methods is expected to generate new algorithms to improve the security of the data, especially images. This is a new modern and classic concept to maintain data integrity. ![]() Morse code is one of the communication codes used in the Scouting field. New techniques are used by combining several algorithms, one of which is the incorporation of hill cipher method and Morse code. ![]() A combination of Cryptography and Steganography is one effort to improve data integrity. Cryptography and Steganography is a growing data security science. Efforts are made to reduce the number of cybercrime is to find new techniques in securing data such as Cryptography, Steganography and Watermarking combination. Saleh Ahmar, Ansari Rahim, RobbiĬybercrime is one of the most serious threats. Nofriansyah, Dicky Defit, Sarjon Nurcahyo, Gunadi W. The larger dimensions of the image, then the smaller MSE that means error of image gets smaller.Ī New Image Encryption Technique Combining Hill Cipher Method, Morse Code and Least Significant Bit Algorithm MSE and PSNR results are not influenced file format or file size, but influenced by dimensions of image. jpg at a resolution of 512 x 512 pixels, 256 x 256 pixels. Message successfully inserted and extracted back on all samples with a good image formats *. The result of merging techniques can maintain the confidentiality of messages because people who do not know the secret key used will be difficult to get the message contained in the stego-image and the image that has been inserted can not be used as a cover image. The technique is combined with steganography techniques Least Significant Bit. In application of cryptographic techniques that will be used is Hill Cipher. Encryption algorithm that used to encrypt message to be sent (plaintext into messages that have been randomized (ciphertext is cryptography and steganography algorithms. It is necessary for the safety that can be used to protect data transmitted through the Internet. But in these activities can also pose a security risk for confidential information. Hill Cipher and Least Significant Bit for Image Messaging Securityĭirectory of Open Access Journals (Sweden)įull Text Available Exchange of information through cyberspace has many benefits as an example fast estimated time, unlimited physical distance and space limits, etc.
