• Cryptanalysis of a Pseudorandom Generator for Cross-Border E-Commerce 

  Shi, Lelai; Liu, Suhui; Petrovic, Slobodan (Journal article; Peer reviewed, 2019)

  In this paper, we study ciphertext-only cryptanalysis of a cascade of pseudorandom sequence generators employing linear feedback shift registers (LFSRs) with so-called irregular clocking. The cascade of LFSRs is a well-known ...

• A conceptual framework for smart city international standards 

  Guo, Hong; Gao, Shang; Li, Jingyue; Xue, Haona (Journal article; Peer reviewed, 2018)
