摘要： A key authentication method between a user equipment (UE) and a serving network (SN) for binary CDMA network and a key re-authentication method during which the UE performs a handover within the same SN in binary CDMA network are provided. The key authentication method for the user equipment includes receiving a terminal authentication request message from a wireless access point, transmitting a terminal authentication response message that includes identification information for the user terminal, receiving user authentication request message that includes at least two random numbers and code information for message authentication from the wireless access point, and transmitting a user authentication response message that comprises first information that is generated using a master key.

摘要： A method and apparatus for generating a keystream are provided. The method includes: (a) receiving a bitstream comprised of at least 4 bits; (b) selecting at least two bits from the received bitstream; (c) generating an operation value by performing a predetermined bitwise operation on the bits selected in (b); and (d) determining whether to discard the received bitstream or to output the rest of the received bitstream not selected in (b) according to the operation value. The method and apparatus for generating a keystream are expected to be suitable for a ubiquitous computing and network environment and to provide high security or high efficiency.
