Allot CTO outlines post-quantum readiness steps for mobile operators

Dr. Yaakov Stein, VP CTO of Allot, discusses post-quantum readiness inside mobile networks in an interview with Help Net Security. He explains which operator traffic remains sensitive for years, such as subscriber identity mappings, billing records and call metadata, and which becomes worthless within hours.

Stein recommends starting with a comprehensive crypto inventory, then migrating TLS interfaces to hybrid key exchange, followed by IPsec links and other public-key protocols. He warns that vendor responses like ‘we are waiting for the standards to stabilize’ indicate a lack of understanding, and that missing a single interface can undermine the entire PQC effort.
