Generalization 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 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 کاملOn the Hardware Implementation of the MICKEY-128 Stream Cipher
2Digital Systems and Media Computing Laboratory School of Science & Technology Hellenic Open University Patras, Greece e-mail: [email protected] ABSTRACT Encryption algorithms are becoming more necessary to ensure the securely transmitted data over insecure communication channels. MICKEY-128 is a recently developed stream cipher with two major advantages: (i) the low hardware complexity, which r...
متن کاملideological and cultural orientations in translation of narrative text: the case of hajji baba of isfahan
در میان عواملی که ممکن است ذهن مترجم را هنگام ترجمه تحت تأثیر قرار دهند، می توان به مقوله انتقال ایدئولوژی از طریق متن یا گفتمان اشاره کرد. هدف از این تحقیق تجزیه و تحلیل جنبه های ایدئولوژیکی و فرهنگی متن مبدأ انگلیسی نوشته جیمز موریه تحت عنوان سرگذشت حاجی بابای اصفهانی ( 1823) و ترجمه فارسی میرزا حبیب اصفهانی(1880) بوده است.
Aes - 128 Cipher . Minimum Area , Low Cost Fpga Implementation
−− The Rijndael cipher, designed by Joan Daemen and Vincent Rijmen and recently selected as the official Advanced Encryption Standard (AES) is well suited for hardware use. This implementation can be carried out through several trade-offs between area and speed. This paper presents an 8-bit FPGA implementation of the 128-bit block and 128 bit-key AES cipher. Selected FPGA Family is Altera Flex ...
