ECDLP Quantum Cryptanalysis

We demonstrate genuine quantum cryptanalysis of the Elliptic Curve Discrete Logarithm Problem up to 14 bits on IBM's 156-qubit Heron R2 processor. Unlike planted-key demonstrations, our implementation uses a full group operation oracle that recovers private keys without prior knowledge.

Solving ECDLP over F p with Pre-computation via Representation Technique

, 2020
We present a new algorithm solving the elliptic curve discrete logarithm problem (ECDLP) with pre-computation. Our method is based on recent work from Delaplace and May (NuTMiC 2019) which aims to solve ECDLP over some quadratic field F p 2 using the so ...

Semantics-Based Verification of an Implemented Shor Oracle for ECDLP in Qrisp

Shor-style quantum algorithms for the elliptic-curve discrete logarithm problem (ECDLP) are highly sensitive to the exact semantics of their group-operation oracles.

Choosing Coordinate Forms for Solving ECDLP Using Shor's Algorithm

CoRR
The primary concerns lie in the limited significance and novelty. While the paper explores the use of projective coordinates, quantum resource requirements are worse than those achieved with previously studied affine coordinates, as carefully documented in the ...

Brace for impact: ECDLP challenges for quantum cryptanalysis

Precise suites of benchmarks are required to assess the progress of early fault-tolerant quantum computers at economically impactful applications such as cryptanalysis. Appropriate challenges exist for factoring but those for elliptic curve cryptography are either too sparse or inadequate for standard applications of Shor's algorithm.
