Abstract
Data privacy and integrity are critical factors in certain Wireless sensor network (WSN) application areas demanding security. Many cryptographic algorithms have been proposed to meet the security requirements of these. The digital envelope is one of the practices used to attain privacy, authentication, integrity, maintenance, and non-repudiation in e-commerce channels. However, the WSN nodes have various constrained resources, like limited battery energy, less computational power and small memory. Elliptic curve cryptography (ECC), one of the Public key cryptographic (PKC) security techniques, which can be implemented on the nodes in WSN. This work deals with an implementation of ECC based digital envelope based security model in WSN applications.
