Tutorial: Post-Quantum Cryptography and 5G Security
Speaker: Dr. T. Charles Clancy, Virginia Tech
This tutorial will cover Fifth Generation (5G) mobile broadband standards that will make a fundamental shift in cryptography. Prior generations based their security and privacy principally on symmetric key cryptography. 5G, however, is shifting its core network over to a microservices, cloud-first architecture and is heavily leveraging protocols like TLS and OAuth2.0 to authenticate and authorize transactions. As a result, it is shifting to a PKI-based trust model. This shift is happening just as quantum computing threatens to unravel the security of traditional ciphers such as RSA and ECC. This tutorial highlights the need to advance the 3GPP 5G standards and NIST post-quantum cryptography standards in tandem, with the goal of launching a “quantum ready” 5G core network.
