Abstract In our modern digital society, cryptography is vital to protect the secrecy and integrity of transmitted stored information. Settings like commerce, electronic banking, or simply private email communication already rely on encryption signature schemes. However, today’s cryptographic schemes do not scale well, thus are suited for increasingly large sets data they used on. For instance, ...

Scalable spaces are simply connected compact manifolds or finite complexes whose real cohomology algebra embeds in their of (flat) differential forms. This is a rational homotopy invariant property and all scalable formal; indeed, scalability can be thought as metric version formality. They also characterized by particularly nice behavior from the point view quantitative theory. Among other res...

The e-Learning technologies makes users capable of accessing a large amount of learning objects created in various parts of the world and across many cultures. Due to the semantic heterogeneity of learning objects built within different cultural contexts, the use of these learning objects by learners is often ineffective. However, developing learning objects in a way that would not only allow t...
