Abstract
The invention relates to an encryption and authentication method for communication software, which is applicable to encryption and authentication for intercommunication software. The applied environment of the invention requires that a receiver can obtain the characteristics of a sender when the receiver receives the communication message sent by the sender in the communication system. The invention is applicable to communication between part A and part B, the process of part B sending message to part A is the same as that of part A sending message to part B. The keypoint of the invention is that in every process of the communication, identity authentication is carried out on the sender by the receiver, if identity password sent by the sender is wrong, the receiver discards the received communication message so that illegal sender cannot send messages correctly. The method in the invention ensures that if the software of the sender is decrypted, the decrypted software of the sender can not be in normal use as long as the software of the receiver is not decrypted.
Description
Technical field
The present invention relates to software technology field.
Technical background
Encrypt, just might be decrypted.Common encryption method is as long as the cracker deciphers the function that just can use encryption software behind the software of own use.
At communication software, this encryption method has overcome this drawback.In communication software, this encryption method can all will prevent that transmit leg from using decryption software through a transmit leg validity checking when each communication.
Even if cracked the communication software that self uses so this encryption method can be guaranteed the cracker, but as long as recipient's communication software is not cracked, the cracker also can't use normally to crack and send message to the recipient so.
The characteristics of this encryption and authentication method are exactly: each communication all can be carried out the transmit leg authentication by the recipient.Unless this has guaranteed all recipient's software is all cracked, otherwise can't guarantee that the recipient can normally receive the message that sends from a transmit leg that cracks.
Summary of the invention
For solving the decrypted problem of communication software, the invention provides a kind of communication software encrypted authentication system, comprising: communication system S, transmit leg A, recipient B, transmit leg identification cipher P
A, recipient's identification cipher P
B, transmit leg feature V
A, recipient's feature V
B, encryption algorithm F, transmission content T.
Described communication system S is used to described transmit leg A and described recipient B that a kind of platform of communication capacity is provided;
Described transmit leg A is used for described transmit leg identification cipher P
AWith send the communication end point that content T sends to the described communication system S of described recipient B;
Described recipient B, whether be used to receive message and can analyze described transmit leg A is the communication end point of the described communication system S of validated user;
Described transmit leg feature V
A, be used for character pair at the described transmit leg A of described communication system S sign;
Described recipient's feature V
B, be used for character pair at the described recipient B of described communication system S sign;
Described transmit leg identification cipher P
A, whether be used at the described transmit leg A of described communication system S sign is one group of information of validated user;
Described recipient's identification cipher P
B, whether be used at the described recipient B of described communication system S sign is one group of information of validated user;
Described encryption algorithm F is used for described communication system S, utilizes described transmit leg feature V
A(or described recipient's feature V
B) calculate transmit leg identification cipher P
A(or recipient's identification cipher P
B) a kind of cryptographic algorithm.
Wherein, described transmit leg A will send the identification cipher P of described transmit leg
ASo that whether described recipient B can judge described transmit leg A is validated user.
Wherein, described recipient B can receive the identification cipher P that comprises described transmit leg
AInformation and can be according to described transmit leg feature V
AComputations goes out the identification cipher F (V of described transmit leg A
A), and the identification cipher F (V of the described transmit leg A that will calculate
A) with the identification cipher P of the described transmit leg that receives
ACompare, judge whether transmit leg is validated user.
If it is legitimate sender that described recipient B judges described transmit leg A, then receive message.Otherwise dropping packets.
Description of drawings
Fig. 1 is the implementation process of system among the embodiment.
Embodiment
1, encryption algorithm F has all been realized in transmit leg A and recipient B inside.Encryption algorithm F is maintained secrecy to the user.Transmit leg A to the message content that recipient B sends is: identification cipher P
A+ transmission content T;
2, after recipient B received communication message, recipient B was at first with the S of query communication system, thus the feature V of acquisition transmit leg
A, recipient B uses the feature V of encryption algorithm F according to transmit leg then
AComputations goes out its identification cipher F (V
A), recipient B compares F (V then
A) and P
AIf, F (V
A)=P
A, transmit leg A is exactly a validated user so, and recipient B can receive this message, otherwise transmit leg A is exactly the disabled user, and recipient B abandons this message.
The present invention judges the identity of transmit leg by the recipient at every turn in communication process, thereby the software that can avoid being cracked uses normal communication function.
