Randomness properties of stream ciphers for wireless communications

In this paper we evaluate the randomness properties of four synchronous stream ciphers for use in wireless communications. These ciphers are: SNOW 3G, ZUC, and AES, all of which are a part of the current LTE standard, and the WG-16 stream cipher. The randomness testing is performed with the NIST SP 800-22 test suite, and its results are accordingly tabulated. In addition, we also examine the autocorrelation properties of the keystreams.
