Cybersecurity and non-state actors: a historical analogy with mercantile companies, privateers, and pirates by Egloff, F

“…Second, the analogy to mercantile companies focuses on the attacks against Google (2009), the attacks against Sony Pictures Entertainment (2014), and the collaboration between large technology companies and Five-Eyes signals intelligence agencies. </p> <p>The thesis makes three main claims: first, the analogy to piracy and privateering provides a new understanding of how state proximity is used politically by attackers and defenders, and offers lessons for understanding attribution in cyberspace. …”

Joint reconstruction of Reed-Solomon encoder and convolutional interleaver in a noisy environment by Swaminathan, Ramabadran, Madhukumar, A. S., Wang, Guohua, Ting, Shang Kee

“…Blind estimation of code and interleaver parameters plays a vital role in various applications such as non-cooperative systems, adaptive modulation and coding, signal intelligence, etc. The present paper proposes novel algorithms to jointly estimate code and interleaver parameters from Reed-Solomon (RS) coded and convolutionally interleaved data stream based on the rank ratio and non-zero-mean-ratio values for noiseless and noisy environments, respectively. …”
