This library also contains all the necessities for the ECDH and ECDSA algorithms.
Parameter to is time needed for curve ECDH key and ECDH parameters generation with the specific curve.
By using ECDH scheme, it can be partially predict the round off key size value of a particular key ring in the sensor network.
The simulator revises the games one by one and imbeds an ECDH problem into the protocol in the last game.
In such case, if A can successfully distinguish between the value returned from the session and a random value and win the AKE security game, then we can solve the ECDH problem using A as a subroutine, i.
4] happens and S can get mnP and solve the ECDH problem by using A.
However, the probability of this event is also bounded by the advantage of breaking the ECDH problem.
The proposed scheme provides strong anonymity against an active adversary if the ECDH problem is hard.
The ECDH key exchange serves as the main frame that is modified to provide an authenticated key exchange.
SSK is obtained from the ECDH key exchange by using prime192 curve, one of the recommended curves that produce a 192-bit shared secret.
The computation can significantly be reduced by using 128-bit (16 byte) of an AES key instead of a 600-bit public key of ECDH prime192.
It is achieved by using the known light cryptographic protocols such as ECDH key exchange and Salsa20 stream cipher.
