Network black-gray industry identification method and device and computer equipment

The invention relates to a network black-grey industry identification method and device and computer equipment. The method comprises the following steps: encrypting a black website fingerprint by using a preset reversible encryption algorithm to obtain an encrypted ciphertext and a key corresponding to the ciphertext; and in a preset confidential environment, decrypting the ciphertext by using the key, and matching the decrypted fingerprint of the black website with the plaintext data of the website to be identified by using the directed acyclic graph to obtain a black label of the plaintext data of the website to be identified. By adopting the method, the problem of poor confidentiality of the existing network black-gray industry identification method can be solved. 本申请涉及一种网络黑灰产业识别方法、装置和计算机设备。所述方法包括：利用预设的可逆加密算法，对黑产网站指纹进行加密，得到加密后的密文和密文所对应的密钥；在预设的保密环境中，利用密钥对密文进行解密，并利用有向无环图，对解密得到的黑产网站指纹以及待识别的网站的明文数据进行匹配，得到待识别的网站的明文数据的黑产标签。采用本方法能够解决现有的网络黑灰产业识别方法存在保密性差的问题。
