The public key cryptography (PKC) is essential for securing many applications in smart grid. For the secure use of the PKC, certificate revocation schemes tailored to smart grid applications should be adopted. However, little work has been done to study certificate revocation in smart grid. In this paper, we first explain different motivations that necessitate revoking certificates in smart grid....
The public key cryptography will play an essential role in securing the smart grid communications. For the secure use of the public key cryptography, an efficient and secure certificate revocation scheme specially tailored to smart grid architecture should be adopted. In this paper, we study certificate revocation in smart grid and design efficient and scalable certificate revocation schemes. The...
The public-key cryptography is indispensable for securing the smart grid communications. In this paper, we propose a hierarchical and fully-connected public key infrastructure that considers the smart grid characteristics. In the proposed public key infrastructure, each certificate authority is responsible for managing the public-key certificates for a geo-bounded small area. We also propose a novel...
