SoK: Research Motivations of Public-Key Cryptography

본문 미리보기

The design, proposal, and analysis of cryptographic primitives (schemes and protocols) is one of the primary research fields in cryptology. To advance this research field, in this paper, we systematically introduce the research motivations for proposing new constructions (for a primitive) in public-key cryptography. We found that all research motivations aim to produce more benefits for certain users, including practicality, security, and functionalities, although some of the benefits may not b
