In IP-based WSN surveys, they recomand that IPsec must change IKE by another leightweight KMS, and also IEEE 802.15.4 MAC must have a KMS for its AES algorithm.
Can we use the same KMS for both of IPsec and IEEE 802.15.4 MAC? how?
thank you
you haven't really use same KMP for Internet IPsec and 802.15.4 because 15.4 devices have lighter hardware capabilities. Check out documents of IEEE 802.15.9 which currently proposes several KMPs for 802.15.4. E.g. HIP base exchange is a possible way to set up IPsec tunnels in the internet, but for 15.4 it is replaced with HIP Diet Exchange. E.g. in 15.4 hardware sometimes there is no hash function like SHA1 needed for IPsec so there is a need to use AES-CBC for generating a hash, use of ECC instead of RSA, ECQV implicit certificates, etc
If i have a new X method for changing security keys, always in the context of IP-based WSN communications, my question is: when it's about an IP communication, IPsec use this method, and if it's about a one hop communication between nodes, Link layer use this method, this is feasible? or i have to implement two methods for both communications security?
