π-Cipher: Authenticated Encryption for Big Data
In today’s world of big data and rapidly increasing telecommunications, using secure cryptographic primitives that are parallelizable and incremental is becoming ever more important design goal. π-Cipher is parallel, incremental, nonce based authenticated encryption cipher with associated data. It is designed with the special purpose of providing confidentiality and integrity for big data in tr...
متن کاملA Block Cipher using Rotation and Logical XOR Operations
Cryptography is the study of methods of sending messages in disguised form so that only the intended recipients can remove the disguise and read the messages. Information security has become a very critical aspect of modern communication systems. With the global acceptance of the Internet as a medium of communication, virtually every computer in the world is connected to every other. It has cre...
متن کاملImage Encryption Using Advanced Hill Cipher Algorithm
The Hill cipher algorithm is one of the symmetric key algorithms that have several advantages in data encryption. But, the inverse of the key matrix used for encrypting the plaintext does not always exist. Then if the key matrix is not invertible, then encrypted text cannot be decrypted. In the Involutory matrix generation method the key matrix used for the encryption is itself invertible. So, ...
متن کاملImage Encryption Using Chaos and Block Cipher
In this paper, a novel image encryption scheme is proposed based on combination of pixel shuffling and new modified version of simplified AES. Chaotic baker’s map is used for shuffling and improving S-AES efficiency through S-box design. Chaos is used to expand diffusion and confusion in the image. Due to sensitivity to initial conditions, chaotic baker’s map has a good potential for designing ...
متن کاملAn Efficient Stream Cipher Algorithm for Data Encryption
Nowadays the data telecommunication security has been provided by most of well-known stream cipher algorithms which are already implemented in different secure protocols such as GSM, SSL, TLS, WEP, Bluetooth etc. These algorithms are A5/1, A5/2, E0 and RC4. On the other hand, these public algorithms already faced to serious security weakness such that they do not provide enough security of prop...
