A Key Establishment Scheme for WSN Based on RC4 and ECC Algorithms
Kang Chen · Journal of Jiangxi University of Science and Technology · 2010
By analysing the security and connectivity,which exist in three classical types of the key establish schemes for wireless sensor network,this paper presents a new key establishment scheme based on RC4 cryptosystem and Menezes-vanstone(M-V)elliptic curve cryptosystem.The scheme adoptes RC4 to encrypt and decrypt datas,and transfers keys by using M-V cryptosystem..Comparing with random key pre-distribution scheme,this method has advantages in space complexity,connectivityand security.With some calculations and simulations,it demonstrates that this scheme has lowered the storage and improved the security and connectivity.
