(1) Loading locally stored downloaded advertisements;
(2) Loading the content pushed by the locally stored system, decrypting the content by using the filled terminal RSA private key to obtain an advertisement signature and a platform RSA public key;
(3) The loaded advertisement content uses RSA algorithm, advertisement signature and platform RSA public key to make signature verification;
(4) And playing the advertisement with the signature verification passed.
The RSA algorithm is an asymmetric encryption algorithm. Decryption may be accomplished without directly passing the key. This ensures the security of the information and avoids the risk of hacking caused by direct transfer of the key. Is a process of encrypting and decrypting by a pair of keys, which are respectively called a public key and a private key. The two are related mathematically, the principle of the encryption algorithm is to guarantee the security by the difficulty of factoring a very large integer.
Compared with the prior art, the invention has the beneficial effects that:
The invention adds the link of authorization verification on the basis of conventional account password verification, can effectively avoid the risk of the account being stolen, replaces plaintext communication by using a bidirectional encryption communication method, can protect advertisement content from being hijacked and tampered by a network, and can prevent the situation that advertisement files locally cached by advertisement terminal equipment are directly replaced by signature verification during each play. The terminal is guaranteed to finally play the expected advertisement content.
