Optimized architecture for SNOW 3G

Abstract

SNOW 3G is a synchronous, word-oriented stream cipher used by the 3GPP standards as a confidentiality and integrity algorithms. It is used as first set in long term evolution (LTE) and as a second set in universal mobile telecommunications system (UMTS) networks. The cipher uses 128-bit key and 128 bit IV to produce 32-bit ciphertext. The paper presents two techniques for performance enhancement. The first technique uses novel CLA architecture to minimize the propagation delay of the 2<sup>32</sup> modulo adders. The second technique uses novel architecture for S-box to minimize the chip area. The presented work uses VHDL language for coding. The same is implemented on the FPGA device Virtex xc5vfx100e manufactured by Xilinx. The presented architecture achieved a maximum frequency of 254.9 MHz and throughput of 7.2235 Gbps.

4G Network Security Algorithms: Overview

“…This work proposed to enhance the SNOW-3G cipher stream [26,27] by using HCPRNG (Hyperchaotic Pseudo-Random Number Generator). The goal is to improve the complexity and randomness of the normal SNOW-3G encoding stream that is twice its initialization mode resulting in a fail based on the short key flow data set in the NIST test [28][29][30]. The digital disruption LFSR (Linear Feedback Shift Register) sequences and the digital production of the SNOW-3G uniform cipher element over one hyperchaotic generator used as a PRNG are depicted in figure (4) below to illustrate the proposed architecture (Pseudo-Random Number Generator).…”

“…Finally, the technology performs admirably and can be scaled up to 4G security by combining plain text The LTE 128-EEA1 confidentiality algorithm is combined with the EIA1-128 integrity control algorithm.

By using the architecture novel Modulo CLA more than 232 to reduce the publishing delay in the Federated States of Micronesia, which makes the decision decisive the algorithm of delay [15,[31][32][33] These designs save 6 KB of memory as compared to existing designs.…”
