摘要:Wireless communications faces less hacking immunity than wired communications. With the increase of dependability on wireless data transfer and calling, the need to develop new rigid algorithm is needed to add more levels of security on the wireless data. In the fact, the effort that is continuously putted in hacking the wireless transmitted data is more than the effort that is putted in building secure communication channels. This paper presents a packet transfer security model for wireless communication by the mean of cryptography and complex transformation. A secret key encryption / decryption algorithm was invented and presented in this paper. The encryption algorithm is demonstrated to decrypt the message and convert it to meaningless rapish data. The cryptographic encryption / decryption of the wireless packet is a first level security procedure, while the second level of security is being added by sending not the encrypted packet itself, but the complex transformation of that packet. This paper compares two reliable transforms; discrete cosine transforms (DCT) and discrete wavelet transform (DWT). The comparison between those two transforms is made, and conclusion is shown in the last.
