Pushing the limits of one-time signatures
Kemal Biçakcı · 2009
Computational and security advantages of one-time signatures come together with their length restrictions. In most applications, one-time signature should be accompanied with one-time public key(s) to enable multiple signing with a single certified public key. This is why most of the time decreasing the size of one-time signature at a cost of larger public key is not what we desire. In this paper, we show the most efficient one-time signature construction proposed so far in the sense that the total length of a signature and a public key is minimized.
