to the server 44 it uses the etls public key and associated url to communicate through the etls servlet 48 steps 62 68 illustrate two secure etls transmissions between the client 42 and the server 44 after the etls public key and associated url have been received and stored by the client 42 to establish a secure connection using the etls protocol the client 42 first establishes a random etls session key and encrypts it with the etls public key received from the custom http response header the client 42 then uses the etls session key to encrypt the bulk data that makes up its service request to the server 44 and also to encrypt a digital time stamp in step 62 the client 42 transmits the data to the etls servlet preferably in the form of an http post request that includes the encrypted session key service request and time stamp once the etls servlet 48 has received the http post request the request is decrypted and compared to a connection log to establish that the transmission is original at this point the security of the communication has been established and the etls servlet 48 may perform a fetch response operation with the http server 46 then once a response from the http server 46.
