Using Colors to Improve Visual Cryptography for Black and White Images,ery few participants, namely . = 2,3, the proposed . (2,.)-threshold schemes have no pixel expansion! We prove that the above two cases are the only ones where it is possible to provide schemes without pixel expansion. That is, we prove that, in the . model, it is not possible to construct (2,.)-thr承认 发表于 2025-4-1 08:25:48

Characterization of the Relations between Information-Theoretic Non-malleability, Secrecy, and Authprobability (over the choice of secret key), and show that any authentication scheme implies approximate non-malleability. Since authentication is possible with a shared secret key of length roughly log., the same applies to approximate non-malleability.
