IET Information Security, Volume 15, Issue 1, Page 107-116, January 2021., 2021 Abstract Authenticated key exchange protocol is widely applied in the Internet services. Lattice‐based key exchange protocols turn out to be quantum‐resistant and hence have attracted tremendous attention. A lattice‐based explicit authenticated key exchange protocol is constructed by combining an IND‐CPA key encapsulation mechanism with a strong EUF ...

Improved Torsion-Point Attacks on SIDH Variants [PDF]
, 2021 SIDH is a post-quantum key exchange algorithm based on the presumed difficulty of finding isogenies between supersingular elliptic curves. However, SIDH and related cryptosystems also reveal additional information: the restriction of a secret isogeny to ...

SIDH-sign: an efficient SIDH PoK-based signature [PDF]
, 2022 We analyze and implement the SIDH PoK-based construction from De Feo, Dobson, Galbraith, and Zobernig. We improve the SIDH-PoK built-in functions to allow an efficient constant-time implementation.

, 2023 We show that the soundness proof for the De Feo-Jao-Plut identification scheme (the basis for supersingular isogeny Diffie--Hellman (SIDH) signatures) contains an invalid assumption, and we provide a counterexample for this assumption---thus showing the ...

, 2023 Isogeny-based cryptography is one of the candidates for post-quantum cryptography. SIDH is a compact and efficient isogeny-based key exchange, and SIKE, which is the SIDH-based key encapsulation mechanism, remains the NIST PQC Round 4.

Attacking B-SIDH Using Castryck-Decru's Key Recovery Attack on SIDH [PDF]
, 2023 Fundamentet i nesten alle offentlige nøkkelkryptografier ligger i vanskeligheten til spesifikke matematiske problemer. Selv om det ikke eksisterer effektive løsninger for disse problemene på klassiske datamaskiner, presenterer kommende kvantemaskiner en ...

Efficiency of SIDH-based signatures (yes, SIDH) [PDF]
, 2023 In this note we assess the efficiency of a SIDH-based digital signature built on a weakened variant of a recent identification protocol proposed by Basso et al.

Case Reports in Dermatological Medicine, Volume 2026, Issue 1, 2026.The management of pyoderma gangrenosum (PG) remains a formidable clinical challenge due to its complex, multipathway immunopathogenesis. Although conventional steroid therapy and advanced biologic agents have improved outcomes, a substantial proportion of patients, particularly those with severe, progressive ulceration, exhibit treatment‐refractory ...
