An Elliptic Curve in Two Parts Although many existing forms of elliptic curve cryptography, such as ECDSA, are vulnerable to quantum computers, this is a consequence of the specific nature of the algorithms and not a weakness of elliptic curves themselves. endobj xڭZKs�6��W�m�Z�"�z�m��lf��ةT������QKR����ŋjɣɦj��$H�$ ��6�M�����/o���mRm�4Ti�ln��U�6y��q 0�[�5H�5d�¶����b.���>��Od_r��? 13 0 obj 359 0 obj Appligent AppendPDF Pro 5.5 A 160 bit elliptic curve cryptographic key could be broken on a quantum computer using around 1000 qubits while factoring the security-wise equivalent 1024 bit RSA modulus would require about 2000 qubits.

In conjunction with specific algorithms developed in the scientific community, quantum computing can undermine the mathematically hard problems that underpin almost all currently used public-key cryptography, including the well-known RSA and elliptic curve cryptography standards.

Because those two problems will be readily and efficiently solved by a sufficiently large-scale quantum computer, we are looking now at cryptography approaches that appear to be resistant to an attacker who has access to a quantum computer. RSA encryption is in fact still widely used in today’s society. 5 Google and IBM have universal quantum computers, … In conjunction with specific algorithms developed in the scientific community, quantum computing can undermine the mathematically hard problems that underpin almost all currently used public-key cryptography, including the well-known RSA and elliptic curve cryptography standards. 355 0 obj The above problems exist if we continue using elliptic curve cryptography based systems. endobj 2 0 obj <>/MediaBox[0 0 612 792]/Parent 12 0 R/Resources<>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/StructParents 23/Tabs/S/Type/Page>> NIST has standardized some elliptic curve cryptosystems, see FIPS 186-4 and SP 800-56B. A fully developed quantum computer using Shor’s algorithm, a polynomial-time quantum computer algorithm for integer factorization, will be capable of cracking a 2048-bit RSA implementation in perhaps as little as a few days. /Filter /FlateDecode stream What we traditionally call Elliptic Curve Cryptography (working in the group of points on an elliptic curve over a finite field) is vulnerable to an attack by a quantum computer running Shor's algorithm and is thus not considered a Quantum-Safe or Post Quantum Cryptographic algorithm. endobj 4 However, there are reports that D-Wave’s quantum speedup analysis is debatable.
