摘要： 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. According to the invention, the transmitting/receiving unit has a controller, which is connected to the receiving unit and the control unit and is designed d) to evaluate a second data frame, received by the receiving unit within a predefined time interval after the transmission of the first data frame, and to determine whether the second data frame contains an acknowledgment message for the successful receipt of the first data frame by the second transmitting/receiving device, and e) not to relay the second data frame to the control unit, if it is determined that it contains the acknowledgment message.

摘要： 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. The embodiments may provide an improved encryption/decryption architecture including an on-chip memory for performing on-the-fly encryption and/or on-the-fly decryption in the framework of 802.11i security enhancement.
