Alternative Security Options in the 5G and IoT Era

  • Schinianakis D.

This article attempts to provide a set of new directions and ideas for research in the ever vibrant fields of telecom and IoT security. It attempts by no means to present a complete set of security solutions; this would be by definition impossible. It rather serves as a short but comprehensive introduction to various technologies and cryptographic techniques in the area of lightweight cryptography in our quest to address the security challenges in the IoT and 5G-connectivity era. We use the term lightweight cryptography interchangeably both for symmetric and suitable asymmetric ciphers, thus covering all aspects of traditional cryptography namely encryption/decryption, authentication, identification, nonrepudiation, integrity protection, and key exchange. Possible usecases that challenge the applicability of lightweight cryptography as well future projections for further discussions are also offered.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

  • Wu Q.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
