| Abstract: | This paper discusses a special thought which uses the active objects to deal with non-preemptive multitasking and discusses problems about the platform security in Symbian OS that is the current popular operation system in the market of smart phone.It interprets 5 sectors of security including capability,permission, authorization,secure identifier and data Caging.3 basic concepts are analyzed including active object,non-preemptive multitasking and asynchronous function.Analysis is carried out to the process of processing from the Security.It resolves the problem about current OS of smart phone from two aspects: a little memory and the platform Security. |
