متن کاملGeneralization of Vigenere Cipher
A generalized way of Vigenere cipher is proposed. Instead of using a Vigenere square for encryption and decryption, any two reversible square matrices whose rows or columns are unique are used for encryption and decryption purpose. One matrix can be easily obtained from the other and hence any one of them can be used for encryption while the other can be derived from the other for decryption. T...
متن کاملModified Least Significant Bit (MLSB)
Steganography is the science of writing hidden messages is such a way that no one except sender and intended recipient can realize there is a hidden message. Compared with cryptography we can say that, steganography’s in security work as supplement to cryptography, not replace it. So to add another layer of protection we can encrypt the hidden message (Johnson & Jajodia, 1998). A survey of curr...
متن کاملAn Improvement of RC4 Cipher Using Vigenere Cipher
This paper develops a new algorithm to improve the security of RC4. Given that RC4 cipher is widely used in the wireless communication and has some weaknesses in the security of RC4 cipher, our idea is based on the combination of the RC4 and the poly alphabetic cipher Vigenère to give a new and more secure algorithm which we called VRC4. In this technique the plain text is encrypted using the c...
متن کاملImage Watermarking Using LSB (Least Significant Bit)
With the rapid development and wide use of Internet, information transmission faces a big challenge of security. People need a safe and secured way to transmit information. Digital watermarking is a technique of data hiding, which provide security of data. This paper presents a watermarking technique which least significant bits (LSB), its steps and its process with matlab images.
