Abstract
Método para realizar una firma digital de grupo, comprende: i) generar, por una tercera parte de confianza (T), una clave privada para cada miembro (F1, F2, …, Ft) de un grupo (G); ii) seleccionar aleatoriamente, dicha tercera parte de confianza (T), un miembro de dicho grupo (G) para que actúe como firmante encargado de firmar un documento digital (M) en nombre del grupo (G); iii) elaborar, dicho firmante, una firma digital de grupo usando su clave privada para firmar dicho documento digital (M); y iv) verificar dicha firma digital de grupo. El método comprende generar, por dicha tercera parte de confianza (T), una clave pública común para todos los miembros de dicho grupo (F1, F2, …, Ft) y usar dicha clave pública común para realizar dicha verificación de la firma digital de grupo de la etapa iv).Method for performing a digital group signature, comprising: i) generating, by a third party trust (T), a private key for each member (F1, F2, ..., Ft) of a group (G); ii) randomly select, said third trusted party (T), a member of said group (G) to act as a signer in charge of signing a digital document (M) on behalf of the group (G); iii) prepare, said signer, a group digital signature using its private key to sign said digital document (M); and iv) verify said digital group signature. The method comprises generating, by said third party trust (T), a common public key for all members of said group (F1, F2, ..., Ft) and using said common public key to perform said verification of the digital signature of stage group iv).
