Abstract:

With the rapid development of Android smart mobile devices, its security issues emerge in endlessly. However, the sandbox mechanism, signature mechanism and access control of permission provided by Android system has its drawbacks, and unable to cope with a variety of security problems at present. Given the lack of access control mechanisms for the protection of communication components, this paper presents an enhanced security access control scheme, in which signature mechanism is used to sign the components in the scheme and achieve enhanced security access control for components communication need to be protected, and certificate verification is checked in the Android Framework layer. Experimental results show that the scheme can be effective for the security access control of process validation, and improve the security of the communication component.

Key words: Android, access control, signature mechanism, security
