The independent password of sending end input, above-mentioned second user name can be the box name of receiving terminal, and the first above-mentioned password can
Be receiving terminal input independent password.
In a kind of optional scheme, before transmitting terminal A obtains first key K from privacy enhanced mail server ES, send
End A needs to log in privacy enhanced mail server ES, and transmitting terminal A can send first user name and the first password PA2To privacy enhanced mail
Server ES is logged in.
In another kind of optional scheme, the second Mail Contents C is obtained from privacy enhanced mail server ES in receiving terminal B1With
3rd key K2Before, receiving terminal B needs to log in privacy enhanced mail server ES, and receiving terminal B can send second user name and the
Two password PB2Logged in privacy enhanced mail server ES.
Alternatively, in the above embodiment of the present invention, in transmitting terminal or receiving terminal privacy enhanced mail server is first logged into
In the case of, said method also includes：
What step S122, the first registration request that privacy enhanced mail server receiving end/sending end sends, or receiving terminal sent
Second registration request, wherein, the first registration request includes：First user name and the 3rd password, the second registration request includes：Second
User name and the 4th password.
Specifically, the 3rd above-mentioned password can be send end subscriber mailbox entry password, the 4th above-mentioned password
It can be the entry password of the mailbox for receiving end subscriber.
Step S124, privacy enhanced mail server is set up with mail server and is connected, and to the first registration request or the second note
Volume request is verified.
Step S126, if the first registration request or the second registration request are proved to be successful, privacy enhanced mail server sends
Information to transmitting terminal or receiving terminal, wherein, information be used for point out the password of user input first or the second password.
Step S128, privacy enhanced mail server receiving end/sending end send the first password or receiving terminal send second mouthful
Order.
In a kind of optional scheme, if needed without registering on privacy enhanced mail server ES before transmitting terminal A
To be registered on privacy enhanced mail server ES, registered user name can be the first user name of transmitting terminal A, and log-in password can
Being the 3rd password PA of transmitting terminal A1, privacy enhanced mail server ES can connect the mail server S at mailbox place to be carried out
Checking, is verified, and proves that transmitting terminal A is the validated user of the mailbox, while privacy enhanced mail server ES can require that A is defeated
Enter the first password PA independent on a privacy enhanced mail server ES2, first password PA2Can be used for privacy enhanced mail server
Belong to the key of all privacy enhanced mails of transmitting terminal A on ES.
In another kind of optional scheme, if no on privacy enhanced mail server ES before receiving terminal B registered,
Needs are registered on privacy enhanced mail server ES, and registered user name can be the second user name of receiving terminal B, log-in password
Can be the 4th password PB of receiving terminal B1, privacy enhanced mail server ES can connect the mail server S that the mailbox is located and enter
Row checking, is verified, and proves that receiving terminal B is the validated user of the mailbox, while privacy enhanced mail server ES can require B
The second independent password PB on one privacy enhanced mail server ES of input2, second password PB2Can be used for privacy enhanced mail service
Belong to the key of all privacy enhanced mails of receiving terminal B on device ES.
Alternatively, in the above embodiment of the present invention, in step S110, receiving terminal uses second user name and the second password
After logging in privacy enhanced mail server, said method also includes：
Step S130, privacy enhanced mail server obtains the label information of key corresponding with second user name, wherein, label
Information at least includes：Turn to encrypt or do not turn encryption.
Specifically, each key for storing in privacy enhanced mail server ES has label, the key is recorded in label whether
Turned encryption.
Step S132, from key corresponding with the second user name, obtain label information is privacy enhanced mail server
The second key encrypted is not turned.
Step S134, privacy enhanced mail server is decrypted to the second key, obtains first key.
Step S136, privacy enhanced mail server is encrypted using the second password to first key, obtains the 3rd key.
Second key is replaced with the 3rd key by step S138, privacy enhanced mail server.
In a kind of optional scheme, receiving terminal B receive transmitting terminal A transmission Email C0 after, if with
It is front to register in privacy enhanced mail server ES, then can be input into second user name and the second password PB2Log in privacy enhanced mail service
Device ES, privacy enhanced mail server ES can search the key of all privacy enhanced mails of receiving terminal B, then read the mark of each key
Sign, it is the key for not turning to encrypt to obtain all labels, i.e., be not decrypted first by the key ESK of privacy enhanced mail server ES
Reuse the second password PB2The key being encrypted, namely the second key K1, it is possible to use the key of privacy enhanced mail server ES
ESK decrypts the second key K1After obtain first key K, reuse the second password PB2It is encrypted and obtains turning the key after encryption,
That is the 3rd key K2, while privacy enhanced mail server ES can use the 3rd key K2The second key K that covering finds1。
A kind of preferred embodiment of the invention is described in detail with reference to Fig. 2, as shown in Figure 2, there is provided a kind of
