An asynchronous communication system and method are configured for secured communication between a sender and a recipient without a need for pre-arrangement of shared static encryption key secrets. In one embodiment a system receives an initiation request for authentication from a sender seeking to transmit a message. The system generates an asymmetric key set, which includes a private key and a public key associated with a key reference. The system stores the private key with the key reference and transmits the public key to the sender. The sender uses the public key to encrypt the message to be sent to the recipient. The system will then receive a request for the private key from a recipient of the encrypted message. The system will authenticate the recipient identity. Once authenticated, the system transmits the private key to the recipient, which uses the private key to decrypt the encrypted message.
