Abstract: A device for transmitting and receiving is disclosed that includes: a) an antenna, b) a transmitting/receiving unit for transmitting and receiving data according to a communications standard, which has a transmitting unit, connected to the antenna, for transmitting first data frames to a second transmitting/receiving device and a receiving unit, connected to the antenna, for receiving second data frames from the second transmitting/receiving device, and c) a control unit, connected to the transmitting/receiving unit for controlling the transmitting/receiving unit, whereby the control unit is designed (c1) to instruct the transmitting/receiving unit to transmit a first data frame and (c2) to receive the second data frame from the transmitting/receiving unit.

Abstract: A block transfer technique is provided for controlling a data transfer to and/or from a WLAN (Wireless Local Area Network) device connected to a data processing system. The data processing system comprises an operating system independent access controller and a platform specific data block transfer engine. The operating system independent access controller is configured to prepare the platform specific data block transfer engine to perform the data transfer to and/or from the WLAN device.

Abstract: A communication device for performing cryptographically secured communication in a WLAN (Wireless Local Area Network) network is provided that comprises a security enhancement unit and a MAC (Medium Access Control) unit. The security enhancement unit is for encrypting plaintext data frames into encrypted data frames and/or decrypting encrypted data frames into plaintext data frames. The MAC unit is for managing communication between communication devices within the WLAN network by coordinating access to a shared wireless communication medium through which communication signals are transmitted. The security enhancement unit and the MAC unit are adapted to perform an on-the-fly encryption process and/or on-the-fly decryption process thereby exchanging the encrypted data frames without buffering the encrypted data frames after encryption or prior to decryption, respectively.
