Definition: The term "isogenotypic" refers to a property that can be used in cryptography to make it difficult for an attacker to determine whether two messages are identical or not. In the context of digital signatures, one common method used to implement isogeny-based signatures is called the Elliptic Curve Cryptosystem (ECC). This system uses elliptic curves over finite fields to generate a signature and verify its authenticity. The key idea behind this approach is that if two messages are generated using
