摘要
WCDMA R4核心网MSC Server中所有模块的稳定运行都离不开安全可靠的数据。MSC Server的数据主要分为两大部分,一部分是存放在内存数据库中的数据,一般存储一些设备的属性和其他的一些公共数据,变化频率相对不是很高;而另一部分主要是各个子模块自己需要的动态数据,是由业务临时产生的一些数据,变化频率较高,实时性要求较高。
     这两部分数据有相互独立的一面,又有相互关联的一面。整个系统的运行都离不开这两部分数据的安全性。任何一部分数据出现问题都会导致设备无法正常地运行,致使系统故障,给运营商和用户带来巨大损失。而要保证数据的安全性,在进行数据保护时就会损失效率,这也是电信级应用所不想看到的结果。从某种意义上说,MSC Server的可靠性依赖于MSC Server中数据的安全性。而安全性又制约着系统效率,因此在数据保护机制中一个兼顾安全性和效率的设计方法就显得尤为重要。
     本论文分析了现有的数据保护机制和国内外对此的最新研究成果,在数据保护中采用一种新的设计思路,在保证数据保护安全性的前提下,提高了数据保护机制的效率;改进了原有的静态数据的保护机制,设计并实现了一个完整的动态数据保护机制。
The stable work of all the modules of WCDMA R4 CN MSC Server is dependent on safe and reliable data. The data of MSC Server are divided into two parts: one for depositing the data of data base, generally the properties of some equipments and some other public data whose changing frequency are not so high; the other for dynamic data needed by each sub module which is temporarily produced and has high changing frequency. These two parts are dependent while somewhat separate. The running of the whole system can' t leave the safety of the data of the two parts. Problems of any of the two parts will induce abnormal running and malfunction which will give large loss to users and merchants. However, to ensure the safety of data, efficiency will be lost during the processor of protecting data, which is not anticipated by the application of telecom level. To some degree, the reliability of MSC Server depends on the safety of data in MSC Server. As safety restricts efficiency, it' s so important to bring up such a met
    hod which will give attention to both safety and efficiency in data protection mechanism.
    This paper analyzes existing data protection mechanism and the newest research results of this field. This paper gives a new designing method which will raise the efficiency of data protection mechanism while at the same time ensuring the safety of data protection. The original static data protection mechanism is improved by designing and realizing a complete dynamic one.
