    Abstract:

    ZUC is a data stream cipher, easy to implement, one of the fastest algorithms to encrypt messages in mobile communications. Because of the key and initialization vector large size (128-bits), ZUC provides high security and is enough resistant to many types of attacks: Weak Key Attacks, Guess-and-Determine Attacks, Algebraic Attacks, Timing Attacks, but not enough robust to withstand the DPA (Differential Power Analysis) type attack. This article makes an analysis of ZUC algorithm and presents the encryption efficiency, and its vulnerabilities; also it is made a comparison with other algorithms used in telecommunications (SNOW 3G, Kasumi, DES/3DES and AES).
