Abstract: 3rdGeneration
Partnership Project (3GPP) has proposed the Authentication and Key Agreement (AKA)
protocol to achieve the security requirements of Evolved Packet System (EPS) in
the Long Term Evolution (LTE) network, called (EPS-AKA) protocol. Nevertheless,
the EPS-AKA protocol is still has some drawbacks in authentication process due
to inherit some weaknesses from the predecessor protocols. This paper proposes
a secure anonymity Key of Authentication and Key Agreement (SAK-AKA) protocol
for LET network to enhance the security level of EPS-AKA protocol. The same
security architecture of EPS-AKA is used by the proposed protocol without
adding extra cost to the system. Specifically, the SAK-AKA protocol increases the
difficulty of defeating the authentication messages by complete concealing of
IMSI with perfect forward security. The extensive security analysis proves that
the SAK-AKA protocol is secure against the drawbacks of current EPS-AKA
protocol. Moreover, the performance analysis in terms of the bandwidth
consumption, the authentication transmission overhead and the storage
consumption demonstrates that the SAK-AKA protocol relatively is more efficient
than the current EPS-AKA protocol.
