A Chaos-Based Authenticated Cipher with Associated Data

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...

COBRA: A Parallelizable Authenticated Online Cipher Without Block Cipher Inverse

We present a new, misuse-resistant scheme for online authenticated encryption, following the framework set forth by Fleischmann et al. (FSE 2012). Our scheme, COBRA, is roughly as efficient as the GCM mode of operation for nonce-based authenticated encryption, performing one block cipher call plus one finite field multiplication per message block in a parallelizable way. The major difference fr...

VMPC-MAC: A Stream Cipher Based Authenticated Encryption Scheme

A stream cipher based algorithm for computing Message Authentication Codes is described. The algorithm employs the internal state of the underlying cipher to minimize the required additional-toencryption computational effort and maintain general simplicity of the design. The scheme appears to provide proper statistical properties, a comfortable level of resistance against forgery attacks in a c...

LAC: A Lightweight Authenticated Encryption Cipher

A Novel Authenticated Cipher for Rfid Systems

In this paper, we present RBS (Redundant Bit Security) algorithm which is a low-complexity symmetric encryption with a 132-bit secret key. In this algorithm redundant bits are distributed among plaintext data bits to change the location of the plaintext bits in the transmitted data without changing their order. The location of redundant bits inside the transmitted data represents the secret key...
