Q: Is NTRU broken?

swineoneToday a new paper appeared on ePrint, "Improved Provable Reduction of NTRU and Hypercubic Lattices". It claims that: this is the first provable result showing that breaking NTRU lattices can be reduced to finding shortest lattice vectors in halved dimension, thereby providing a positive response...

Q: What prevents ZKP proofs to be misused by others?

user60588In ZKP, if a prover P1 possesses a secret number S and generates a proof PRF for the possession of the same with the aim to prove it to a verifier V1. But, what prevents V1 from misusing the PRF and present itself to others as the one in possession of the secret S (misrepresenting itself as P1)? ...

Q: The advantages of using KEM compared to applying traditional PKE approach

User0258I am studying a thesis on the design of a key encapsulation mechanism (KEM). In section 2.6 (page 18) of this thesis, the following explanation is given about the difference between KEM and common methods: KEM is a method used by two parties to derive a symmetric key using public-key cryptograph...
