Breaking the Hidden Irreducible Polynomials Scheme [PDF]
In 2019 G\'omez described a new public key cryptography scheme based on ideas from multivariate public key cryptography using hidden irreducible polynomials. We show that the scheme's design has a flaw which lets an attacker recover the private key directly from the public key.

Public Key Cryptography based on Semigroup Actions [PDF]
A generalization of the original Diffie-Hellman key exchange in $(\Z/p\Z)^*$ found a new depth when Miller and Koblitz suggested that such a protocol could be used with the group over an elliptic curve.

Applications of single-qubit rotations in quantum public-key cryptography [PDF]
We discuss cryptographic applications of single-qubit rotations from the perspective of trapdoor one-way functions and public-key encryption. In particular, we present an asymmetric cryptosystem whose security relies on fundamental principles of quantum ...

Public-Key Cryptography Based on Tropical Circular Matrices [PDF]
Some public-key cryptosystems based on the tropical semiring have been proposed in recent years because of their increased efficiency, since the multiplication is actually an ordinary addition of numbers and there is no ordinary multiplication of numbers

Watermarking public‐key cryptographic functionalities and implementations: The case of encryption and signatures [PDF]
A watermarking scheme for a public‐key cryptographic functionality enables the embedding of a mark in the instance of the secret‐key algorithm such that the functionality of the original scheme is maintained, while it is infeasible for an adversary to ...

Revocable identity‐based matchmaking encryption in the standard model
Identity‐based Matchmaking Encryption (IB‐ME) is an extension notion of matchmaking encryption (CRYPTO 2019), where a sender and a receiver can specify an access policy for the other party.

Lattice‐based unidirectional Proxy Re‐Encryption and Proxy Re‐Encryption+ schemes
The concept of Proxy Re‐Encryption (PRE) was introduced by Blaze, Bleumer and Strauss at Eurocrypt in 1998. In this concept, a semi‐trusted proxy user acquires a re‐encryption key from the delegator.

On Multiple Encryption for Public-Key Cryptography
Using multiple, individual encryption schemes is a well-established method to increase the overall security of encrypted data. These so-called multiple encryption or hybrid schemes have regained traction in the context of public-key cryptography due to ...
