Proxy signature scheme
Abstract:
Technologies are generally described for proxy key generation, and signature generation and validation. In some examples, a cryptographic key generation system may include an original key generation unit configured to generate a public key and a private key for an original signer, a proxy key generation unit configured to generate one or more proxy public keys and one or more proxy private keys for one or more proxy signers, and a transmitter configured to transmit the proxy private keys respectively to the one or more proxy signers.
