In this paper, the requirements for information security are presented in the ubiquitous ecological(u-Eco) city. The various definition of ubiquitous city is analyzed first, the concept of the u-Eco City, services and major projects are then presented. The framework of the integrated operating center for u-Eco city is proposed, the privacy, data security and network facility protection in the center are analyzed. Unlike to previously proposed security algorithms, the light-weight encoding algorithms(such as block/stream encoding, pseudo-random generator, hash function, and public key encoding) in the u-Eco city center are required to communicate the information in the ubiquitous sensor network. Furthermore, the principal policies guaranteeing the secrecy and authentication for the private information are also presented.
