A data security protection method generates dynamic encryption keys and dynamic decryption keys for a host and a client during data transmission between the host and the client. The host stores a host initial key K, and determines a host key Kusing a one-way hash function based on the host initial key K. The client stores a client initial key K', and determines a client key K′using the one-way hash function based on the client initial key K′. Original data Ris encrypted as encrypted data Xusing the host key Kbefore being sent to the client. The client decrypts the encrypted data Xusing the client key K′, to obtain the original data R.
