https://doi.org/10.1007/978-3-322-91146-9We exploit the unique features of the .-sibling Intractable hashing method in presenting two authentication schemes. In the first scheme, we propose a method which enables intermediate nodes in IP communication networks to verify the authenticity of transit flows. While in the second scheme, we introduce a new one-time digital signatures scheme.
