摘要： A method for waking a device from a power save mode to an active mode includes: transmitting, by a first device, a magic packet through a predetermined channel to a second device, which operates in the power save mode by repeating a doze state and an awake state according to a predetermined period of time, for notifying the second device to switch to the active mode; and retransmitting the magic packet to the second device through the predetermined channel if a response to the magic packet has not been received from the second device and a predetermined time has not elapsed after transmitting the magic packet through the predetermined channel.

摘要： An encryption-based security protection method and apparatus are provided. The method includes generating a random key pattern table in order to allocate a plurality of random key patterns of original data to be transmitted; generating an address pattern table in order to allocate a plurality of address patterns of addresses in which the original data is stored; and generating a mapping table in order to map the plurality of random key patterns and the plurality of address patterns. The apparatus includes an address pattern table generation unit; a random key pattern table generation unit; a mapping table generation unit; and an internal memory unit which stores the address pattern table, the random key pattern table, and the mapping table.
