Embodiment Construction
[0039] Such as Figure 10 As shown, this streaming media information security guarantee method is a symmetric encryption algorithm, and the encryption includes the following steps:
[0040] (1) Read in the password, and analyze the initial sign, the operation control word and the password, if the analysis is wrong, then exit and give an error message; if the analysis is correct, then perform step (2);
[0041] (2) De-align the operation control word and password according to the analytical value of the start flag;
[0042] (3) Carry out group calculation to the cipher controlled by each control operation word, and form the final cipher block;
[0043] (4) according to the length of each cipher block, the plaintext to be encrypted is grouped to form a group set;
[0044] (5) According to the encryption algorithm specified in the operation rule field of the operation control word, the corresponding password is used to encrypt and calculate the plaintext to be encrypted, and fi...
