Conclusion

Ericsson’s mobile platforms contain a variety
of security mechanisms and an advanced
model for issuing and checking the integrity
of software. Manufacturers of mobile
phones can thus build secure applications
and a secure process for issuing platform
software. Apart from communication security
and basic platform integrity control,
mobile phone developers can decide how
and when they want to use these mechanisms.
Therefore, additional security mechanisms
might be needed.
The mobile platforms do not use an open
software environment that permits end
users to install new software modules or
applications. This limits the need for further
software-protection mechanisms. In
the future, however, we might see a more
PC-like situation, where new native software,
such as non-Java software, can easily
be installed and executed. In that case,
non-trusted software will have to be isolated
from trusted software . Advanced operating
systems isolate non-trusted software
in such a way that it is never allowed
to interfere with the execution of trusted
software. In a large and flexible OS, however,
isolation is difficult to achieve.
Therefore, other means, such as hardware
mechanisms or more stringent security requirements
(in the OS) will have to be employed.
