Abstract:
A proxy-based encryption method includes generating, according to a private key of a sending end and a public key of a receiving end, proxy keys that correspond to at least two proxy servers, respectively. The number of the proxy keys is equal to the number of the proxy servers. The method further includes sending encrypted ciphertexts and the proxy keys that correspond to the at least two proxy servers respectively to the at least two proxy servers, respectively, so that the at least two proxy servers re-encrypt the encrypted ciphertexts according to the corresponding proxy keys.
