Embodiments of the present invention disclose a proxy-based encryption method, a proxy-based decryption method, a network equipment, a network device and a system, which can improve the reliability and security of proxy-based transmission of encrypted files. The 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, where the number of the proxy keys is equal to the number of the proxy servers; and 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, |
