Receiving terminal also can comprise: the accumulation module divided data that receives is accumulated, and the data of being accumulated are carried out threshold decision, and the data that will reach threshold value sends to the data check module.
Whether this data check module can further be obtained the cryptographic Hash of the data that reach threshold value, and correct according to the described data that reach threshold value of cryptographic Hash verification, and the data that verification is correct are stored.
Should default cut apart unit and can be 1K, this threshold value can be greater than 1K.
According to another aspect of the present invention, provide based on point-to-point data transmission method, be used to send the transfer of data of being undertaken by network channel between terminal and the receiving terminal, may further comprise the steps: A. sends terminal to be cut apart unit and cuts apart data waiting for transmission according to default, and divided data is transferred to receiving terminal by network channel; B. receiving terminal carries out verification to the divided data that receives.
Wherein, also can comprise before the steps A: the default unit of cutting apart is set in sending terminal.
Wherein, step B can comprise:
B1. receiving terminal is accumulated divided data, and the data of being accumulated are carried out threshold decision;
B2. the data that reach threshold value are carried out verification.
Step B2 can further comprise: obtain the cryptographic Hash of the data that reach threshold value, and whether correct according to the described data that reach threshold value of described cryptographic Hash verification, and the data that verification is correct are stored.
Before step B1, also can comprise: threshold value is set at receiving terminal.
Should default cut apart unit and can be 1K, this threshold value can be greater than 1K.
According to said system of the present invention and method, can make that the data volume in the network channel diminishes, therefore the bandwidth that takies is less, thereby has improved data transmission bauds.
