In business-oriented chat applications, end-to-end encryption is needed to prevent governments and service providers from eavesdropping or leaking information.At NTT Secure Platform Laboratories, we are working on a prototype secure business chat system that not only prevents leakage from terminals by not leaving any data on the terminals, but also makes it possible to exchange and search messages without disclosing any secrets to the server.This article introduces the encryption technology used in this prototype system.
