Disclosed is a cathode for a lithium secondary battery and a lithium secondary battery comprising the same. The cathode may include a current collector, a first composite layer formed from a mixture of olivine-type lithium iron phosphate cathode active material powder and a binder on the current collector, and a second composite layer formed from a mixture of olivine-type lithium iron phosphate cathode active material powder and a binder on the first composite layer. A specific surface area of the olivine-type lithium iron phosphate cathode active material powder in the second composite layer may be at least 1.2 times larger than that of the olivine-type lithium iron phosphate cathode active material powder in the first composite layer. The cathode for a lithium secondary battery has excellent safety, high energy density, and high output performance.

A specific surface area of the olivine-type lithium iron phosphate cathode active material powder in the second composite layer may be 0.8 times or less that of the olivine-type lithium iron phosphate cathode active material powder in the first composite layer. The cathode for a lithium secondary battery has excellent stability, high energy density, and improved cycle life characteristics.

An information protection system includes a mobile terminal and an encryption module. The mobile terminal requests a key sequence by transmitting a message including a Personal Identification Number (PIN) number input by a user, and encrypts or decrypts one or more communication signals, including voice signals and data signals, based on the key sequence when the key sequence is received. The encryption module is connected to the mobile terminal. The encryption module encrypts a security key using the identifier and the PIN number of the mobile terminal, decrypts the encrypted security when requested by the mobile terminal, and transmits the key sequence generated based on the decrypted security key to the mobile terminal.
