Abstract

The invention provides a routing table generation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a first AID sent by an equipment host DH; generating a routing table according to the first AID; receiving a notification message sent by each security module SE in a connected state, the notification message carrying a second AID; andupdating the routing table based on the notification message. Therefore, on the basis of generating the routing table according to the first AID sent by the DH, the routing table based on the AID is dynamically updated by collecting the second AID sent by the SE, the technical problem that the coverage range of the routing table is limited due to the fact that the first AID sent by the DH is imperfect is avoided, and the effectiveness and reliability of the routing table are improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method, device, electronic equipment and storage medium for generating a routing table. Background technique [0002] In order to ensure the security of wireless communication devices, especially NFC (Near Field Communication, near field communication) devices, SE (Secure Element, security module) is usually set as a component to store sensitive information and provide a Secure Execution Environment. In an NFC device, there are usually multiple SEs that can work at the same time, and the way of implementing routing through the routing table can implement routing to all SEs. [0003] In related technologies, the routing table is generated by relying on the AID sent by the DH. However, when the AID sent by the DH is not perfect, the coverage of the routing table is bound to be limited, making the reliability of the routing table extremely low. Ther...
