The wireless transfer protocols do not necessarily guarantee the security of the communication, e.g. confidentiality or integrity of the data. |

That is but one of the many reasons why security must be considered on |
58 |
|
higher levels as well. Even application layer solutions are commonplace, |

|
e.g. using cryptographical means to protect data have been integrated in |

mail and chat clients (in tools such as pgp [], gpg [], silc [], ..). |

When considering mobile use, there may be different requirements for the |
63 |
|
application layer software than in conventional stationary use. For example, |
64 |
|
applications used in mobile phones must be cheap in terms of CPU to save |
65 |
|
power and expense. Thus the solutions that have been developed for |
66 |
|
stationary use (more powerful machines) must be additionally evaluated with |
67 |
|
the small devices etc. in mind. Obviously, wireless connections can be used |
68 |
|
for stationary devices as well (e.g. satellite stations are very |
69 |
|
stationary), so there power distinction does not apply. |
