Aggregate Proxy Signature and Verifiably Encrypted Proxy Signature

  title={Aggregate Proxy Signature and Verifiably Encrypted Proxy Signature},
  author={Jin Li and Kwangjo Kim and Fangguo Zhang and Xiaofeng Chen},
An aggregate signature is a single short string that convinces any verifier that, for all 1 ≤ i ≤ n, signer i signed message mi, where the n signers and n messages are distinct. The main motivation of aggregate signatures is compactness. In this paper, the concept of aggregate proxy signature (APS) is first proposed to compact the proxy signatures. Furthermore, a concrete APS scheme is constructed, which can be proved to be secure under the security model of APS. Additionally, as an application… CONTINUE READING
