isogeniapohjaiset

Isogeniapohjaiset refers to concepts or systems that are based on the principle of isogeny. Isogeny, in a mathematical context, is a special type of surjective homomorphism between groups that has a finite kernel. This concept is particularly important in the study of elliptic curves, where isogenies provide a way to relate different elliptic curves. An isogeny between two elliptic curves is a non-constant rational map that preserves the group structure.

When applied to algorithms or cryptographic schemes, "isogeniapohjaiset" implies that these systems leverage the properties of isogenies. For example, in post-quantum cryptography, isogeny-based cryptosystems have emerged as a promising alternative to traditional public-key cryptosystems that are vulnerable to quantum computers. These systems often rely on the hardness of finding isogenies between supersingular elliptic curves. The security of such schemes is believed to be based on the difficulty of solving the elliptic curve isomorphism problem or related problems. The mathematical underpinnings of isogeniapohjaiset systems are complex and involve advanced number theory and algebraic geometry. Research in this area continues to explore new constructions and analyze their security and efficiency.
