METHOD AND ARRANGEMENT FOR EFFICIENT INFORMATION NETWORK KEY EXCHANGE

摘要

The invention relates to a method and arrangement for efficient distribution of Internet key exchange using Internet Key Exchange protocol (IKEv1 and IKEv2) securely in mobile terminal. The objects of the invention are fulfilled by distributing IKEv1 and/or IKEv2 protocol in secure way between mobile equipment and tamper resistant device (TRD), so, that most of the complex public key operations are done in mobile equipment and authentication is done by TRD. In addition there may be a counter for measuring the number of request from outside, which allows only a certain numbers of request and in that way provide security against, e.g. timing and DPA (Differential Power Analysis) attacks.
