    • An apparatus and a method for encrypting a mobile Internet system, and an apparatus and a method for decrypting the mobile Internet system are provided to improve encryption and decryption performance of the system by differently setting encryption and decryption modes according to a service of the mobile Internet system. An apparatus for encrypting a mobile Internet system includes an encryption input selection unit(110), first and second encryption units(120,130), and an encryption output selection unit(140). The encryption input selection unit(110) selectively outputs at least one plaintext inputted from the outside and an initial value corresponding to the number of each plaintext based on an encryption mode set by a sort of a service. The first and second encryption units(120,130) perform an encryption of each block by using the plaintext and the initial value which are selectively outputted from the encryption input selection unit(110). The encryption output selection unit(140) determines an output form of a ciphertext which is encrypted from the first and second encryption units(120,130) according to the encryption mode.

    • An apparatus for wavelength assignment in wavelength multiplexing optical ring networks includes: a node section receiving a connection setup request, the node section comprising a plurality of nodes; and a wavelength assignment controller connected to the node section for, when the connection setup request occurs, determining paths available between the nodes using sparse wavelength conversion and limited wavelength conversion, calculating the total number of gaps for each node available, and assigning wavelengths to a path having the smallest total number of gaps. The present invention assigns wavelengths in consideration of both sparse wavelength conversion and limited wavelength conversion to minimize the call-blocking probability, and uses the wavelength in adjacent partitions to calculate the number of gaps for each wavelength and the total number of gaps.
