    • Abstract


      Proxy signature was first coined by Mambo et al to carry out the signing procedure even in the absence of the original signer to sign the required document. Moreover, occasionally anonymity of proxy signers is required so that no one can reveal their identity, including the original signer. The paper thus proposes a quantum-safe anonymous proxy signature, which provides anonymity to the proxy signers based on the worstcase hardness of lattice problems. The construction is proved to be unforgeable against the adaptive chosen message attacks against the hardness of the small integer solution problem.
