Due to the
fast development in electronic technology, some mobile
devices are designed for new services in important
applications in life. In
this paper, we propose a new method of message security by
using the coordinates in GPS service, where it can specify
the path of movement by taking some coordinates during
travel of mobile node MN and estimate the following
situation of MN in a constant time interval. This new
estimated coordinate is applied in our secret key. Dynamic
Toleration Distance (DTD) is also designed in our key to
increase its practicality. The security analysis shows that
the probability to break this key is almost impossible due
to the security of coordinates and DTD, and adjusting the
length of the Random key. Experimental study shows that the
ciphertext can only be decrypted under the restriction of
DTD. It illustrates that our secret key (Sec_key) is
effective and practical for data transmission in mobile
environment.
