An efficient stream cipher for resistive RAM

2SC: An Efficient Code-Based Stream Cipher

In this article, we present a new code-based stream cipher called 2SC, based on the sponge construction. The security of the keystream generation of 2SC is reducible to the conjectured intractability of the Syndrome Decoding (SD) problem, which is believed to be hard in the average case. Our stream cipher compares favorably with other provably secure stream ciphers such as QUAD and SYND in term...

An 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...

Efficient FPGA Implementation of the RC4 Stream Cipher using Block RAM and Pipelining

RC4 is a popular stream cipher, which is widely used in many security protocols and standards due to its speed and flexibility. Several hardware implementations were previously suggested in the literature with the goal of improving the performance, area, or both. In this paper, a new hardware implementation of the RC4 algorithm using FPGA is proposed. The main idea of this design is the use of ...

Efficient Implementation of "Large" Stream Cipher Systems

Scream: A Software-Efficient Stream Cipher

We report on the design of Scream, a new software-efficient stream cipher, which was designedto be a “more secure SEAL”. Following SEAL, the design of Scream resembles in many ways ablock-cipher design. The new cipher is roughly as fast as SEAL, but we believe that it offers asignificantly higher security level. In the process of designing this cipher, we re-visit the SEALdesign...
