Described security management entity uses the basic secret key decryption of transmission side to go out note expressly and/or real-time short data, is sent to take over party after then using the basic key of take over party to encrypt;
Take over party uses local basis secret key decryption to go out note expressly and/or real-time short data.
In aforesaid method, transmission side send a note and/or in real time short data time, it is also possible to generating a session key, transmissions side uses and is encrypted by note and/or real-time short data content described in the work double secret key of session key and basic secret generating; Transmission side sends described session key, and ciphertext note and/or real-time short data; Security management entity use transmission side's basis key and the session secret generating transmission side work secret key decryption received go out note expressly and/or real-time short data, re-use described session key and take over party basis secret generating take over party work described in double secret key note expressly and/or in real time short data be encrypted, send is to take over party; Take over party uses the session key received and local basis secret generating work secret key decryption to go out note expressly and/or real-time short data.
Further, described transmission side sends after using session key described in local basic double secret key to be encrypted again; After described security management entity uses the basic secret key decryption of transmissions side to go out plaintext session key, re-use plaintext session key described in the basic double secret key of take over party and it is sent to take over party after being encrypted; Described take over party uses local basis secret key decryption to go out expressly session key.
Session key in above-mentioned each method can adopt sequence number, time stamp or randomized number; Basis key can adopt static preset, it is also possible to is derived by authentication mechanism. Especially, the basic key of each user can be all identical, naturally it is also possible to different. In addition, to each user, the basic key of many notes and/or real-time short data can be adopted same with one by the basic key of note and/or real-time short data one to one, it is possible to use two different.
For McWiLL group system, the encryption method that the present invention proposes is described in detail below.
Please refer to accompanying drawing 1, the function of each integral part is described as follows:
UT: the termination function module realizing McWiLL broadband multimedia cluster system network.
McBTS:McWiLL base station network element, it is achieved air interface function, comprises air interface physical layer, MAC layer and Network layer function, and user is linked into different business service networks.
SMC: sms center, is responsible for the forwarding of process note/real-time short data.
SeS: security server.
Embodiment 1: SMS encryption processes
Please refer to accompanying drawing 2, encryption note treatment scheme comprises the steps:
Step 101, UT1 send MO short message sending request message to the McBTS at place;
Step 102, McBTS forward MO short message sending request message to SMC;
Step 103, SMC send MO short message sending response message to McBTS;
Step 104, McBTS send MO short message sending response message to UT1;
Step 105, SMC send note decoding request to SeS, carry the identification number of the short message content after encryption and UT1;
Step 106, SeS inquire corresponding key according to the identification number of UT1, are decrypted by the short message content after encryption, then send deciphering response to SMC, carry the short message content after deciphering;
Short message content after deciphering is stored by step 107, SMC, then sends SMS encryption request to SeS, carries the identification number of expressly short message content and UT2;
Step 108, SeS inquire corresponding key according to the identification number of UT2, are encrypted by short message content, then send SMS encryption and reply to SMC, carry the short message content after encryption;
Step 109, SMC send MT short message sending request to McBTS;
Step 110, McBTS forward MT short message sending request to UT2;
Step 111, UT2 perform deciphering, obtain expressly short message content, then send MT short message sending and reply to McBTS;
Step 112, McBTS forward MT short message sending and reply to SMC.
Embodiment 2: short data encrypt treatment in real time (assuming that each user has identical basic key, it may also be useful to the time stabs as session key)
Please refer to accompanying drawing 3, the flow process that encryption short data sends specifically comprises the steps:
Step 201, UT1 obtain local time stamp, and use basis key and time stamp evaluation work key, after using work double secret key short data content to be encrypted, sending MO short data to the McBTS at place and send a request message, wherein time stamp uses basis key to be encrypted;
Step 202, McBTS forward MO short data to SMC and send a request message;
Step 203, SMC send session secret key request message to SeS, carry the identification number of UT1 and UT2, and the stamp of the time through encryption that UT1 sends;
First step 204, SeS inquire the basic key of UT1 and UT2, and the basic key comparing UT1 with UT2 is identical, then SeS directly sends session key response message to SMC, still carries the time stamp of the encryption in session secret key request message in message;
Step 205, SMC send MT short data request message to McBTS, and wherein time stamp extends this as SeS and replys in message the ciphertext time stamp returned at session key;
Step 206, McBTS forward MT short data request message to UT2;
Step 207, UT2 use basis double secret key ciphertext time stamp to be decrypted, recover expressly time stamp, then use basis key and time stamp evaluation work key, then use work double secret key ciphertext note to be decrypted and recover expressly note, finally send MT short data response message to McTBS;
Step 208, McBTS forward MT short data response message to SMC;
Step 209, SMC send MO short data response message to McBTS;
Step 210, McBTS send MO short data response message to UT1.
In the present embodiment, if the basic key of UT1 and UT2 is different, then SeS needs first decrypted session key, calculates transmission side's work key and deciphers real-time short data; And then calculate take over party and work key and encrypt real-time short data, and use take over party basis key encrypted session key, then the two is sent to take over party, concrete process is similar to the encrypt treatment of note to embodiment 1, repeats no more.
