Embodiment approach
[0074] like figure 1 As shown, according to the first embodiment of the present invention, a method for enhancing the randomness of a random number of an SSL / TLS client is provided, including the following steps:
[0075] (1) The SSL / TLS client uses a pseudo-random number generator to generate a random number CR, and encapsulates the random number CR in a first handshake message and sends it to the SSL / TLS server.
[0076] Specifically, the first handshake message in this step is a Client Hello message, and the random number CR is embedded in a random number (Random) field in the Client Hello message for transmission.
[0077] (2) After receiving the second handshake message sent by the SSL / TLS server in response to the first handshake message from the SSL / TLS server, the SSL / TLS client parses the second handshake message to obtain the server random number SR;
[0078] Specifically, the second handshake message in this step is a Server Hello message.
[0079] In this step, t...
