สรุป	A ring signature is a digital signature scheme allowing a member of a group (ring) to sign a message on behalf of the group without revealing the signer's identity. Proposed by Rivest, Shamir, and Tauman in 2001, ring signatures provide signer anonymity while still proving that the signature comes from one member of a specified set. This cryptographic primitive is widely used in privacy-preserving applications, whistleblowing systems, and anonymous messaging platforms.	Elliptic Curve Cryptography (ECC) is a public-key cryptosystem based on the algebraic structure of elliptic curves over finite fields. Proposed independently by Neal Koblitz and Victor Miller in 1985, ECC offers equivalent security to RSA with much smaller key sizes. Modern cryptography increasingly favors ECC for its efficiency: a 256-bit ECC key provides security comparable to a 2048-bit RSA key, making it ideal for constrained environments and high-performance systems.
