Analytical evaluation of the stream cipher ZUC

Abstract

The new stream cipher algorithm ZUC has been adopted to be the kernel of the third set of the LTE cryptographic algorithms. These security algorithms are used to ensure the data confidentiality and integrity protection during its transmission over the air interface in the LTE Network. In the present paper, we are interested in studying the internal structure of ZUC algorithm and its different operation modes. In addition, we will focus on its analytical evaluation to give a clear idea of its efficiency.

4G Network Security Algorithms: Overview

“…This work is included in the security file of 3GPP LTE Advanced. The scheme with the highest productivity single carries out the stage of work of the ZUC [38][39][40]. Schemes realization ZUC fully ability single realize a lot of lower throughput, ago the self-feedback loop in the high path significantly reduces the operating frequency.…”

“…These algorithms achieved confidentiality and integrity despite their different implementation of time complexity, space complexity, and data complexity. The constant denotes the best running condition for the algorithm, while the exponential denotes the worst running condition [38]. The values will first show the complexity of LTE-based algorithms, and then slice the complexity of each category provided in Table 3 and Table 4 separately.…”

A High Flexible Shift Transformation Unit Design Approach for Coarse-Grained Reconfigurable Cryptographic Arrays

“…Shift transformation, also known as rotation transformation, is widely applied in numerous fields, such as cryptography, image processing, multimedia applications, and biostatistics [11][12][13]. In cryptography, to enhance the "diffusion degree" of plain text, most cryptographic algorithms, such as AES [14], ZUC [15], and SHA−256 [16], leverage shift operations or shift-based variant operations to improve security. The shifters in existing cryptographic processors are mainly the typical barrel shifter [4][5][6][7][8].…”
