Anonymous security authentication scheme using elliptic curve cryptography and hash function in mobile network
In order to prevent personal data from being lacked and improve the existing mobile network roaming anonymous authentication scheme
anonymous security authentication scheme using elliptic curve cryptography and hash functions in mobile network was proposed.With elliptic curve cryptography and hash functions
random numbers were used to replace public key encryption and time stamp.Firstly
before using the roaming services of a foreign agent(FA)
hash function was calculated.A host agent(HA)was used by mobile user to register.Then
authentication and session key were set up with elliptic curve encryption.If HA is always in FA
MU can update the session key with FA.Finally
through a common channel
MU could utilize HA to change their passwords.The analysis of the performance and safety shows that
compared with other similar programs
the proposed scheme has significantly improved efficiency and safety.And the virtual computing time is only 2.000 85 seconds
which sharply reduces the cost of computing.
