In recent years, quantum key distribution (QKD) has been the object of intensive research activities and of rapid progress, and it is now developing into a competitive industry with commercial products. Once QKD systems are transferred from the controlled environment of physical laboratories into a real-world environment for practical use, a number of practical security, compatibility and connectivity issues need to be resolved. In particular, comprehensive security evaluation and watertight security proofs need to be addressed to increase trust in QKD. System interoperability with existing infrastructures and applications as well as conformance with specific user requirements have to be assured. Finding common solutions to these problems involving all actors can provide an advantage for the commercialization of QKD as well as for further technological development. The ETSI industry specification group for QKD (ISG-QKD) offers a forum for creating such universally accepted standards and will promote significant leverage effects on coordination, cooperation and convergence in research, technical development and business application of QKD.
