Abstract

The invention discloses a kind of refreshing method for public key, and the method includes following steps: receiving system start download the corresponding public key according to the different trading time at different client. The receiving system sends the data which containing the index table of public key to the terminal; the terminal receives said data, if the index information of public key not exist in terminal, and then the terminal sends requirement for downloading the public key to the receiving unit according to the index of public key; the receiving system gets the corresponding public key and sends to the terminal according to the requirement of terminal; and the terminal refreshes the public key. Because the time of downloading public key for different client is different, it can avoid the network jam and system paralysis caused by download. At the same time, the terminal batch refreshes the index table of public key, and it can reduce the download time and the occupation for the network, and reduce the cost.
