Elliptic curve encryption method and device, electronic equipment and computer program product

The invention relates to the technical field of encryption, and provides an elliptic curve encryption method and device, electronic equipment and a computer program product. The method comprises the following steps: determining a first elliptic curve and a second elliptic curve according to a private key and a generation point of a curve; according to the first elliptic curve, the second elliptic curve and the torque key, determining a bilinear pairing relation corresponding to points on the first elliptic curve and points on the second elliptic curve, and determining an elliptic encryption curve according to the bilinear pairing relation; and encrypting the to-be-encrypted information according to the elliptical encryption curve to obtain a ciphertext, and sending the ciphertext and the torque key to each authorizer. According to the method, the torque secret key is added in the elliptic encryption curve, under the condition that the secret key of the user is not changed, the torque secret key is used as a p
