A Novel Approach for Security Enhancement in IPsec by a New Secured Internet Key Exchange Protocol
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
IPSec is a network layer security protocol that provides security for internet communications at the IP layer by authenticating and encrypting each IP packet of a communication session. The security properties of IPsec critically depend on the underlying key exchange protocols, known as Internet Key Exchange (IKE). However, IKE is complex and vulnerable due to attacks such as (DOS, replay, etc.). The proposed paper brings a new secured IKE protocol based on onetime password. This protocol uses only the symmetric cryptosystem and is operated in two phases with four messages to accomplish the IPsec SA establishment. It guarantees authenticity of both entities within the same communication session. The proposed protocol ensures secure data transmission between two entities as well as to prevent from the vulnerable attacks.
