Towards hierarchical security framework for smartphones

摘要: With powerful computing capability, plentiful functionality and advanced operating systems with flexible APIs, smartphones have become indispensable part of our daily lives. However, growing functionality, complexity popularity also increased concerns about information security, these been further exacerbated by rich third-party applications. In order to protect significant research standardizations efforts made in recent years. most activities focus on specific issues, which cannot mitigate negative effects as a whole. this paper, we first introduce common architecture including main smartphone assets. Then identify threats are clustered into vulnerabilities attacks. Based the layered structure smartphones, propose hierarchical security framework for hardware system application user data communication security. Finally, present preliminary solutions regard framework, give future direction.
