The Open Handset Alliance (OHA) which comprised of chip makers, handset manufacturers (Samsung, Motorola, LG and so on), software developers, and service providers (T-Mobile) was formed by Google in November 2007 [3], [60].

In order to cope with malware attack, the recent released Android 4.0 (Ice Cream Sandwich) is added with ASLR (Address Space Layout Randomisation) by Google to provide better defence against memory-corruption exploits [84]. ASLR is a computer security technique that randomly arranging the positions of key data areas, so that it is more challenging for attackers to know the exact memory location for key data areas [85].
