Abstract: This paper discusses the problem which exists in designing the operating system of mobile phone through analyzing the platform security design architecture used in Symbian operating system. It interprets three basis conception including unit of trust, capability model and data of improvement and particularizes several measures Symbian uses. It draws out Symbian’s security design idea. On the base of this, it makes suggestions at the end.
