Abstract

The invention provides a high-efficiency authentication method for an alliance chain, belongs to the technical field of data security, and is mainly used for solving the problems of key distribution and high-efficiency authentication in a multi-center environment of the alliance chain. The invention designs an identity-based multi-center digital signature scheme MA-IBS. According to the scheme, under the condition that no trusted center exists, all the centers jointly generate the secret key for the user. A key of a user no longer depends on a certain center to generate storage, and collusionattacks from N-1 centers can be resisted. A user signs a message by using a private key of the user and uploads the message to the alliance chain through the center, and the signature supports efficient batch authentication.

Description

technical field [0001] The invention belongs to the technical field of data security, and relates to a multi-center key distribution and signature authentication method in an alliance chain environment. Background technique [0002] With the rapid development of Internet technology, people have more and more electronic data, and different organizations or institutions hold different or similar data. Due to various interest issues among these organizations, the data between these organizations is often not well shared and authenticated. For example, in the electronic medical environment, after we have seen a doctor in a hospital, we still need to We re-conducted the physical examination because different hospitals could not share data. Secondly, when we need to obtain our own insurance from the Medical Insurance Bureau, we need the hospital to help us obtain a lot of certification materials, because the Medical Insurance Bureau cannot directly certify the hospital's data.
