D1 discloses a software startup method, wherein (1) a user installs a client terminal, launching software by running a launcher, the initiator is launched to read the configuration file and the encrypted data file, and obtain a current system timestamp N1, encrypting the obtained machine MC, software PID, public key B, encrypted cipher PU and time-stamp N1 encrypted with public key B with public key A and then sending to the authorization server in accordance with the service address of the authorization server, starting to request authentication authorization; (2) the authorization server, upon receiving the authorization verification request, decrypts the data packet carried by the verification authorization request using private key A, obtains the corresponding data and performs authorization verification; (3) upon verification by the authorization server, the encrypted timestamp N1, password PU, password PU’ and software hash hashA are encrypted with the public key B and returned to the client, informing the successful authentication; (4) upon receiving, by the client, an authorization response for which the authorization verification is successful, decrypting data carried by the authorization server response using private key B, obtaining an encrypted time N1, a cipher PU, a new cipher PU’ and a software hash value hashA, and decrypting the encrypted time N1 with private key B, resulting in time stamp N2, comparing time stamp N2 with n1 to verify that the communication has been tampered with, the initiator closes the connection with the authorization server, and authorizes the verification (see paragraphs [0066]-[0077], [0139]-[0170] and figures 2, 9-18).
