Abstract
A system for securing wireless communication between a transmitter and a receiver through a physical layer control and a data channel is disclosed. The transmitter includes a pseudo random sequence generator module and an encryption module. The pseudo random sequence generator module receives a protocol input, and an additional input. The pseudo random sequence generator module initializes an initial state with the protocol input and the additional input to obtain a pseudo random sequence code. The encryption module receives a ciphering key and encrypts the pseudo random sequence code with the ciphering to obtain an encrypted secure scrambling code to secure the system through the physical layer control and the data channel.
Claims10
A system for securing wireless communication between a transmitter and a receiver through a physical layer control and a data channel, wherein said system comprises:
- (a) a transmitter memory unit;
- and
- (b) a transmitter processor that is configured to receive a protocol input and an additional input, and initialize an initial state with said protocol input and said additional input to generate a pseudo random sequence code, wherein said pseudo random sequence code comprises plain text;
- receive a ciphering key;
- encrypt said pseudo random sequence code with said ciphering key to generate an encrypted secure scrambling code;
- and
- replace a known scrambling code with said encrypted secure scrambling code in said physical layer control and said data channel to encrypt said physical layer control and said data channel for securing a wireless communication system, wherein said physical layer control comprises said known scrambling code.
A method for securing wireless communication between a transmitter and a receiver through a physical layer control and a data channel, said method comprising:
- receiving a protocol input and an additional input, at said transmitter;
- generating a pseudo random sequence code, at said transmitter, by performing initialization of an initial state with said protocol input and said additional input;
- receiving a ciphering key, at said transmitter;
- encrypting said pseudo random sequence code with said ciphering key to generate an encrypted secure scrambling code;
- and
- replacing a known scrambling code with said encrypted secure scrambling code in said physical layer control and said data channel to encrypt said physical layer control and said data channel for securing a wireless communication system, wherein said physical layer control comprises said known scrambling code.
