Opportunistic Wireless Encryption (OWE) is a Wi-Fi standard which ensures that the communication between each pair of endpoints is protected from other endpoints. Unlike conventional Wi-Fi, it provides "Individualized Data Protection" such that data traffic between a client and access point is "individualized". Other clients can still sniff and record this traffic, but they can't decrypt it.
OWE is an extension to IEEE 802.11.[1] it is an encryption technique similar to that of Simultaneous Authentication of Equals (SAE) and is specified by Internet Engineering Task Force (IETF) in RFC 8110 with devices certified as Wi-Fi Certified Enhanced Open by the Wi-Fi Alliance.[2] [3]
