The Design And Implementation Of IOS APP Development Security Framework

iOS is one of the two most popular mobile operating systems now, and there are over one million APPs in its APP Store. However, even if the APP is approved to be sold in APP Store after Apple’s audit, the APP itself may still have security problems. This article is to show the six most severe problems during the iOS APP development: Unknown status of iOS devices; No code confusion; No verification for APP file; Store important information in insecure area; Could not recognize devices; Could not protect data in the RAM from tampering. The serious consequence of ignoring these problems is shown. Also, after showing the feasibility of solving them, the complete solution is provided.What’s more, a security framework named WNiOSSafe.Framework is designed and complmented (written in Objective-C). After verification of the same APP with and without using the framework, the result is shown:adopting these functions could solve the six problems above. Also, the framework itself could be imported into current projects directly to secure iOS APP.
