| Abstract | ||||
| The wide spread of WLAN and the popularity of mobile devices increase the frequency of data transmission among mobile users. However, most of the data encryption technology is location-independent. Indeed, an encrypted data can be decrypted anywhere. The encryption technology cannot restrict the location of data decryption. Therefore, our objective is to add a layer of security to the network without breaking the network rules and to decrease network traffic. These aims can be achieved by two ways. First, almost all the fractionally encrypted messages sent by senders are decrypted by the receivers by applying the inverse fractional Fourier transform in the same order of rotations. Second, a decrease in the message queuing delay occurs due to the no need for encryption technique as it was achieved by the fractional Fourier transform. In order to meet the demand of mobile users in the future, a location-dependent approach is proposed in this paper. Firstly a target latitude/longitude coordinate must be determined. The coordinate is incorporated with a random key for data encryption by fractional Fourier transform. The receiver can only decrypt the ciphertext when the coordinate acquired from GPS receiver is matched with the target coordinate, and the exact key for fractional transformation is applied. | ||||
