DISTRIBUTED ENCRYPTION AND DECRYPTION METHOD, APPARATUS, SYSTEM AND MEDIUM

Disclosed in the present invention are a distributed encryption and decryption method, an apparatus, a system and a medium. The method comprises: presetting an encryption and decryption SDK in a distributed business service; by means of the encryption and decryption SDK, acquiring an authorization key of business data, and determining an encryption and decryption mode and an encryption and decryption algorithm matched with the business data; and, on the basis of the authorization key, performing encryption or decryption operation on the business data according to the encryption and decryption mode and the encryption and decryption algorithm. The present invention effectively reduces frequent key requests for key management centers, improving the encryption and decryption processing efficiency of fragmented mass data and high-concurrency request scenarios of the Internet of Things. Sont divulgués dans la présente invention un procédé, un appareil, un système et un support de chiffrement et de déchiffrement dis
