Abstract
A distributed Rivest Shamir Adleman (RSA) signature generation method in an ad-hoc network and a signature generation node are provided, including steps for distributing key information to a plurality of nodes using an RSA parameter and a maximum distance separable (MDS) code, in a dealer node, generating a partial signature using the key information and transmitting the generated partial signature to a signature generation node, in the plurality of nodes, and generating an RSA signature using the partial signature, in the signature generation node, wherein the RSA signature is generated using the partial signature, received from a fewer number of nodes than the entire plurality of nodes.
