Rule issuing method and device, electronic equipment and medium

The embodiment of the invention provides a rule issuing method and device, electronic equipment and a medium. The method may comprise: receiving a rule ciphertext issued by a client, the rule ciphertext being generated by the client using a key to encrypt a rule, the key being generated by an encryption chip in a server, the rule being a processing strategy for a quintuple in a received data message, and the processing strategy being a processing strategy for a quintuple in the received data message; and calculating a hash value of the regular ciphertext, determining a storage position corresponding to the hash value, and storing the regular ciphertext in the storage position. 本说明书实施例提供一种规则下发方法、装置、电子设备及介质。该方法可以包括：接收客户端下发的规则密文，所述规则密文是所述客户端使用密钥对规则进行加密生成的，所述密钥由所述服务器中的加密芯片生成，所述规则是针对接收到的数据报文中的五元组的处理策略，计算所述规则密文的哈希值，确定所述哈希值对应的存储位置，将所述规则密文存储于所述存储位置。
