Finding Collisions in a Quantum World: Quantum Black-Box Separation of Collision-Resistance and One-Wayness
post-quantum cryptography one-way permutation one-way trapdoor permutation
2018/11/12
Since the celebrated work of Impagliazzo and Rudich (STOC 1989), a number of black-box impossibility results have been established. However, these works only ruled out classical black-box reductions a...

Semantic-security of individual bits under a ciphertext are fundamental notion in modern cryptography. In this work we present the first results about this fundamental problem for Order-Preserving Enc...

AbstractThis paper shows the first practical semantically secure public-key
encryption scheme such that its one-wayness is equivalent to general
factoring in the standard model (in the sense of IND-...
