Title:
REPLAY ATTACK DETECTION METHOD, APPARATUS, AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/116883
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present invention are a replay attack detection method, apparatus, and device, and a storage medium. The method comprises: receiving message data sent by a data sending terminal, the message data comprising a message body and an associated message authentication code, and the message authentication code being calculated by means of a secure message authentication code function; calculating a comparison authentication code of the message body by means of the secure message authentication code function by using a shared key; and if the comparison authentication code is consistent with the message authentication code, querying whether there is a data record corresponding to the message authentication code, so as to determine whether the message data is a replay attack message. According to the present solution, replay attack and tampering attack behaviors in a network data packet can be quickly and efficiently detected at low system overhead.
