Pairing-free secure-channel establishment in mobile networks with fine-grained lawful interception
Xavier Bultel, Cristina Onete · Proceedings of the 37th ACM/SIGAPP Symposium on Applied Computing · 2022
Modern-day mobile communications allow users to connect from any place, at any time. However, this ubiquitous access comes at the expense of their privacy. Currently, the operators providing mobile service to users learn call metadata, and even the contents of those exchanges. A main reason behind this is the Lawful-Interception (LI) requirement, by which serving networks must provide this (meta-)data to authorities, given a warrant.
