Abstract
Disclosed are a membership proof device and method for ensuring privacy. The disclosed membership proof method includes for ensuring privacy includes performing a first calculation for a user's membership proof using a zero-knowledge proof algorithm and performing a second calculation for the user's membership proof on a user value of the user using a Rivest-Shamir-Adleman (RSA) accumulator-based membership proof algorithm and transmitting results of the first and second calculations to a verifier.
Claims12
A membership proof method for ensuring privacy, comprising:
- performing a first calculation for a user's membership proof using a zero-knowledge proof algorithm and performing a second calculation for the user's membership proof on a user value of the user using a Rivest-Shamir-Adleman (RSA) accumulator-based membership proof algorithm;
- and
- transmitting results of the first and second calculations to a verifier.
A membership proof method for ensuring privacy, comprising:
- generating a Rivest-Shamir-Adleman (RSA) accumulator-based membership proof value through an exponentiation operation on a user value of a user;
- generating a conversion value of the user value using a challenge value of a verifier and a random value;
- and
- transmitting the membership proof value and the conversion value to the verifier.
A membership proof device for ensuring privacy, comprising:
- a memory;
- at least one processor electrically connected to the memory;
- and
- a communicator,
- wherein the processor performs a first calculation for a user's membership proof using a zero-knowledge proof algorithm and performs a second calculation for the user's membership proof on a user value of the user using a Rivest-Shamir-Adleman (RSA) accumulator-based membership proof algorithm, and
- the communicator transmits results of the first and second calculations to a verifier.
