Abstract: The process is initiated by the recipient's requesting an artifact (100) from the sender, who then obtains the recipient's transmission key (102) and separately encrypts the requested artifact and an acknowledgement such that they are decryptable with first and second strictly private keys, respectively, known to and controlled by the sender (104). Next, the sender encrypts the encrypted artifact and encrypted acknowledgement together using the transmission key such that the message is decryptble only with a third strictly private key known to and controlled by the recipient (106), and transmits the encrypted message to the recipient (108). The recipient decrypts the message (110) to recover the encrypted artifact, as well as the encrypted acknowledgement which is returned to the sender (112). The sender decrypts the acknowledgement using the second strictly private key (114) to verify receipt by the recipient of the encrypted artifact and then sends the first strictly private key to the recipient (116) to enable decryption of the encrypted artifact (118).

Abstract translation: 该过程由接收者从发送者请求伪装（100）发起，然后他们分别获得接收者的传输密钥（102）并分别加密所请求的伪像和确认，使得它们可以分别用第一和第二严格私钥解密 已知和由发送者（104）控制。 接下来，发送者使用传输密钥一起加密加密的伪像和加密的确认，使得消息只能被接收者（106）已知和控制的第三严格私有密钥进行解密，并将加密的消息发送到接收者（108） ）。 接收方解密消息（110）以恢复加密伪像，以及返回给发送器（112）的加密确认。 发送者使用第二严格私钥（114）解密确认，以验证接收者是否收到加密伪像，然后将第一严格私钥发送给接收者（116），以使加密神器产生解密（118）。
