We present a constant-round non-malleable commitment scheme based on the existence of sub-exponential one-way functions and using a blackbox proof of security. As far as we know, t...

We propose the concept of fine-grained forward-secure signature schemes. Such signature schemes not only provide non-repudiation w.r.t. past time periods the way ordinary forward-...
