Electronic prescription sharing method and device based on proxy re-encryption

Abstract

The invention relates to an encryption technology and provides an electronic prescription sharing method and device based on proxy re-encryption, computer equipment and a storage medium. The method comprises the steps of: receiving registration information of a main user, and generating an identity identifier in an alliance network system according to the registration information of the main user; when request information of an electronic prescription sharer is received, generating an electronic prescription requester and a public key and a private key corresponding to the electronic prescription sharer; acquiring a first ciphertext, a second ciphertext and a re-encryption key according to the identity identifier of the electronic prescription sharer; encrypting the second ciphertext by using a re-encryption key to obtain a third ciphertext, generating an electronic prescription voucher from the first ciphertext and the third ciphertext, and issuing the electronic prescription voucher to the electronic prescription requester, so that the electronic prescription requester decrypts the electronic prescription voucher to obtain an electronic prescription after the electronic prescription requester passes the verification of the electronic prescription voucher. Since the to-be-registered subject user has a unique identity identifier, so that repeated registration on different platforms is avoided, the efficiency is improved, the cost is reduced, an agent re-encryption technology is adopted in the process, and the security is greatly improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an electronic prescription sharing method, device, computer equipment and storage medium based on proxy re-encryption. Background technique [0002] In recent years, with the continuous introduction and implementation of my country's related "medicine separation" policy, under the medical reform policy, the outflow of hospital "prescriptions" has continued to increase. Now some provinces, cities and regions have formed some electronic prescription sharing models of "Internet + electronic prescription" through relevant policy incentives. my country's Internet hospitals are constantly emerging, and third-party Internet companies such as prescription sharing platforms have also cooperated with local hospitals and pharmaceutical chain companies. [0003] However, there are still many problems in the electronic prescription sharing platform under the traditional centralized Internet...
