According to Straub, OMEMO uses the Double Ratchet Algorithm 'to provide multi-end to multi-end encryption, allowing messages to be synchronized securely across multiple clients, even if some of them are offline'. The name 'OMEMO' is a recursive acronym for 'OMEMO Multi-End Message and Object Encryption'. It is an open standard based on the Double Ratchet Algorithm and the Personal Eventing Protocol (PEP, XEP-0163). OMEMO offers future and forward secrecy and deniability with message synchronization and offline delivery.",

This session key is then used to encrypt data flowing between the parties. This allows for data/message confidentiality, and message authentication codes for message integrity and as a by-product message authentication.",
