Summary:A real time decryption system. A real time decryption system and method utilizing content addressable memory (CAM) for synchronously comparing network addresses in wireless communications. First, a network address table and a decryption key table are provided, wherein the decryption key table comprises a plurality of decryption keys, and the network address table comprises a plurality of network addresses correspondingly. Thereafter, a packet is received, wherein the packet comprises a source address and a ciphertext. The source address is then compared with the network addresses, thus a decryption key from a location of the decryption key table can be obtained according to the network address if one network address matches the source address. At last, the ciphertext is decrypted with the decryption key to generate a plaintext.
