SXDH Assumption

Definition

The SXDH assumption is a cryptographic hardness assumption used to prove the security of certain pairing-based cryptographic schemes. It posits that a specific computational problem related to bilinear pairings on elliptic curves is difficult to solve, even for powerful adversaries. This assumption is crucial for the security guarantees of various advanced cryptographic protocols, including some zero-knowledge proofs and digital signature algorithms. The strength of the SXDH assumption directly influences the trustworthiness of cryptographic constructions that rely upon it.
