Sensitive applications and data wil

Sensitive applications and data will be placed inside encrypted
virtual disk volumes to enforce access control. The encrypted
application volume (EAV) will serve as the embodiment of the
application lockbox. The EAV encryption keys will be placed
inside a trusted key store (TKS). Disadvantage of this system
is data and key both stored on mobile itself. In [2] author
introduced a new mobile ecommerce system solution that can
be used for mobile security for mobile payment. External
encryption device connected to mobile phone by adaptable
interface, the use of mobile phones itself, and SIM cards can
greatly enhance the security of mobile payment through
cross-encryption. But drawback of this system it increases cost
of mobile. In [3] Mobile device identifies the location and then
try to establish a connection to trusted mobile and then send
data within one boundary. Data is in terms of plain text. But
here problem is hacker can modify data while sending from
one mobile to another.
