The present disclosure relates to a block cipher apparatus and method for real-time data transmission and the block cipher apparatus according to an exemplary embodiment of the present disclosure includes: a block encryption unit which selects a key in accordance with an order of keys having different lengths to encrypt each plaintext block and generate a ciphertext block; and a message authentication unit which generates a message authentication code using a key selected at the time of encrypting a current plaintext block which is encrypted in the block encryption unit and a previous message authentication code generated by a plaintext block before the current plaintext block.

Apparatus and method for block ciphers for real-time data transmission

A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a display unit configured to display information; a circuit board having one surface with a plurality of switches thereon; and a keypad disposed over the circuit board and having keys that when pressed, contact corresponding switches on the circuit board. Further, the keypad further includes a plurality of actuators corresponding to and protruding towards the plurality of switches; key-shaped parts laminated on the actuators, respectively, and each having a predetermined height; and a film part disposed to obscure the key-shaped parts and having one surface with key marks in correspondence with the key-shaped parts so as to form the keys of the keypad. In addition, the key-shaped parts and the film part are integrally formed together.

Mobile terminal and keypad manufacturing method thereof

A mobile terminal includes a first body including a front case and a display disposed in the front case, a second body slidably mounted on the first body and a slide module including a slider mounted on the second body. The mobile terminal also includes a guide portion provided to the front case of the first body to guide a slide motion of the slider.
