  • Method and node for generating distributed Rivest Shamir Adleman signature in ad-hoc network
    Patent number: 8645698
    Abstract: A distributed Rivest Shamir Adleman (RSA) signature generation method in an ad-hoc network and a node of an ad-hoc network. The distributed RSA signature generation method in an ad-hoc network includes distributing key share information, which is generated using a maximum distance separable (MDS) code and a random symmetric matrix, to a plurality of nodes; generating, in a fewer number of nodes than the plurality of nodes, a partial signature using the distributed key share information; transmitting the partial signature to a signature generation node; and generating an RSA signature using the partial signature, in the signature generation node.
