对称密码体制的发展趋势将以分组密码为重点。分组密码算法通常由密钥扩展算法和加密（解密）算法两部分组成。密钥扩展算法将b字节用户主密钥扩展成r个子密钥。加密算法由一个密码学上的弱函数f与r个子密钥迭代r次组成。混乱和密钥扩散是分组密码算法设计的基本原则。抵御已知明文的差分和线性攻击，可变长密钥和分组是该体制的设计要点。

To fully utilize the available spectrum for a wireless communication system it is feasible to adapt to different situations on the channel. In this paper a flexible OFDM transmitter is presented together with basic theory behind OFDM transmission. It is shown that high flexibility can be obtained with a reasonable amount Flexible baseband transmitter for OFDM of additional hardware. Part of the design, the FFT-processor, has already been fabricated and measurement results are presented.

Sector is a system infrastructure software that provides functionality for distributed data storage, access, and analysis/processing. It automatically manages large volumetric data across servers or clusters, even those over distributed wide area high speed networks. Sector provides simple tools and APIs to access and/or process the data. Data and server locations are transparent to users, as the whole Sector network is a single networked super computer to the users.
