Technologies related to shared secret identification for secure communication are generally described. In some examples, devices may exchange hashes, such as file deduplication hashes, to identify a matching hash. The identified matching hash represents a shared data item which may be used as a shared secret to encrypt and/or decrypt subsequent secure communications between the devices. Each device retrieves the shared data item from its respective secure memory and may use the shared data item to encrypt and/or decrypt subsequent secure communications. An eavesdropper may observe the hash exchange, but will not be able to decrypt the secure communications without access to the shared data item, because hashes may be effectively non-invertible. |
