Abstract: The present invention belongs to the field of biomedicine, and relates to an inducer for inducing a mesenchymal stem cell to differentiate into an islet cell. An inducer for inducing a mesenchymal stem cell to differentiate into an islet cell consisted of the following components: GLP-1, parathyroid hormone, paracetamol, rapamycin, icariin, trametinib, EPO and VEGF. Each component in a inducer for inducing a mesenchymal stem cell to differentiate into an islet cell of the present invention is safe and non-toxic, requiring fewer steps and short time to induce differentiation, with high induction efficiency.

Abstract: A signature generation method performed by an electronic apparatus is provided. A message abstract is generated according to a to-be-signed message and eigenvalues of a plurality of signature parties, an eigenvalue of a signature party being based on a random number of the signature party. Public keys and sub signatures of the plurality of signature parties are obtained, and a sub signature of the signature party is based on the random number of the signature party, the message abstract, and private keys of the plurality of signature parties. An aggregation public key is generated according to the public keys of the plurality of signature parties, and a length of the aggregation public key is less than a length of the plurality of public keys after splicing. An aggregation signature is generated according to a sum value of the plurality of sub signatures and the message abstract.
