==SECURE COMPUTATION SYSTEM, SECURE COMPUTATION SERVER APPARATUS, SECURE COMPUTATION METHOD, AND SECURE COMPUTATION PROGRAM - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240106654 titled 'SECURE COMPUTATION SYSTEM, SECURE COMPUTATION SERVER APPARATUS, SECURE COMPUTATION METHOD, AND SECURE COMPUTATION PROGRAM

==Simplified Explanation==

The patent application describes a secure computation server apparatus in a secure computation system that includes a table storage part, a table shuffle part, a multiplication part, and a comparative verification part.

* The table storage part stores secret shares of the product of a first value and a second value for combinations of shares of possible values of the first and second values.
* The table shuffle part shuffles indices of possible values of the first and second values in the table.
* The multiplication part selects an element in the table based on the shuffled indices matching the first and second values.
* The comparative verification part accepts data agreed upon by a majority of other secure computation server apparatuses as the correct value out of a plurality of data received from them.

== Potential Applications ==
This technology could be applied in secure multi-party computations, confidential data processing, and secure data sharing platforms.

== Problems Solved ==
This technology solves the problem of securely computing products of values without revealing the individual values to any single party in the computation.

== Benefits ==
The benefits of this technology include enhanced privacy protection, secure data processing, and reliable verification of computation results.

== Potential Commercial Applications ==
Potential commercial applications of this technology include secure cloud computing services, financial data processing systems, and secure communication networks.

== Possible Prior Art ==
One possible prior art for this technology could be secure multi-party computation protocols that involve sharing and processing data securely among multiple parties.

=== Unanswered Questions ===

== How does this technology ensure the security and privacy of the shared data during computation? ==
The technology uses secret sharing techniques and verification mechanisms to ensure the security and privacy of the shared data during computation.

== What are the potential limitations or vulnerabilities of this secure computation server apparatus? ==
The technology may face challenges in terms of scalability, efficiency, and potential attacks on the secure computation system. Regular security audits and updates may be necessary to address any vulnerabilities.


==Original Abstract Submitted==

a secure computation server apparatus in a secure computation system includes: a table storage part that stores a table of secret shares of the product of a first value and a second value for combinations of shares of possible values of the first value and shares of possible values of the second value; a table shuffle part that shuffles indices of possible values of the first value and indices of possible values of the second value in the table; a multiplication part that selects an element in the table whose indices in the shuffled table match the first and the second values; and a comparative verification part that accepts data that a majority of other secure computation server apparatuses agrees on as a correct value out of a plurality of data received from the other secure computation server apparatuses.
