An Efficient and Secure Attribute-Based Signcryption Scheme for Smart Grid Applications
Smart Grid (SG) Ciphertext-Policy Attribute-Based Signcryption (CP-ABSC) scheme Authentication
2018/3/13
With regards to the development of modern power systems, Smart Grid (SG) as an intelligent generation of electricity networks has been faced with a tremendous attention. Fine-grained data sharing in S...
In this paper we consider both ``OR" and ``XOR" based monochrome random grid visual cryptographic schemes (RGVCS) for tt-(k,n)∗(k,n)∗ access structure which is a generalization of the thre...

On the Relation of Random Grid, Probabilistic and Deterministic Visual Cryptography
secret sharing visual cryptography
2014/3/5
Visual cryptography is a special type of secret sharing. Two models of visual cryptography have been independently studied: deterministic visual cryptography, introduced by Naor and Shamir, and random...
Key Predistribution Techniques for Grid-Based Wireless Sensor Networks
Key predistribution wireless sensor networks symmetric key management
2009/6/11
We consider symmetric key predistribution in grid-based wireless
sensor networks. Networks consisting of wireless sensor nodes arranged
in a grid pattern have many useful applications, including env...
