Abstract: An automatic self-calibrated oscillation method and an apparatus using the same are provided. After a static time tuning (STT) table and a run time tuning (RTT) table have been established, the apparatus converts an output clock signal to generate a current RTT value at every predefined time and then compares the current RTT value with a reference RTT value generated in response to a STT value of the STT table, or with an interpolated result generated in response to the reference RTT value to generate a deviation value. Thus, through the deviation value, the output clock signal may be calibrated to address the target frequency without the assistance of external reference clock unit or locked loop unit after the STT table and the RTT table are established.

Abstract: 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 K0, and determines a host key Kn using a one-way hash function based on the host initial key K0. The client stores a client initial key K?0, and determines a client key K?n using the one-way hash function based on the client initial key K?0. Original data Rn is encrypted as encrypted data Xn using the host key Kn before being sent to the client. The client decrypts the encrypted data Xn using the client key K?n, to obtain the original data Rn.
