Definitions

  • the third byte length is one-third to one-fifth of the first byte length; for example, after obtaining a 16-byte digest or a 32-byte hashing value, the value can be verified by a verification method such as crc32 (4 bytes) or crc64 (8 bytes); filling the digest or hashing value verified by the crc into the memoryAddress field of the 0x34 service; before filling, it is also necessary to extract the length of the storage field of memoryAddress, which can be a length of the ALFID
  • the address is confirmed by the lower 4 bits of (addressAndLengthFormatIdentifier), which is a maximum of 16 bytes, and usually 4 bytes are used.
  • the upgrade package verification field obtained by this solution contains the total size of the upgrade package and the digest or hashing value of the upgrade package content, which can be sent to the vehicle system through the 0x34 service.
  • the vehicle system obtains the size and digest or hashing value of the upgrade package to be transmitted, and can perform integrity verification with the subsequent upgrade package obtained through the 0x36 service, without the need for additional DID or RID to passively verify the upgrade package.
  • the present invention discloses a verification field generation system based on DoIP transmission upgrade package, as shown in FIG2, the generation system includes
  • a message detection module used to detect whether the request message information meets the preset conditions, and identify the storage area corresponding to the first address in the request message information as the area to be filled;
  • the message detection module and the upgrade package detection module can be operated in parallel.

Abstract

L'invention concerne un procédé et un système de génération de champ de vérification basé sur un paquet de mise à niveau de transmission DoIP, et un procédé et un appareil de mise à niveau de vérification basée sur un paquet de mise à niveau de transmission DoIP. Le procédé de génération de champ de vérification comprend les étapes suivantes : S1, en réponse à une demande de téléchargement de mise à niveau, obtenir une première valeur fixe par réalisation d'un contrôle d'intégrité sur un paquet de mise à niveau, et obtenir une première valeur de vérification par mesure de la taille du paquet de mise à niveau; S2, vérifier si l'adresse de départ du paquet de mise à niveau stocké dans des informations de paquet de demande satisfait une condition prédéfinie; et si tel est le cas, définir une zone de stockage correspondant à l'adresse de départ en tant que zone à remplir; S3, vérifier la première valeur fixe, puis remplir ladite zone avec la première valeur fixe pour obtenir une seconde valeur de vérification; et S4, encapsuler la première valeur de vérification et la seconde valeur de vérification pour obtenir un champ de vérification de paquet de mise à niveau. Selon la présente invention, aucune instruction supplémentaire n'est requise, et une extrémité de vérification de mise à niveau vérifie activement le paquet de mise à niveau reçu, ce qui permet d'éliminer le risque qu'un système de véhicule soit bloqué en raison de l'échec de la décompression normale ou de l'installation correcte du paquet de mise à niveau, sans augmenter la charge du système de mise à niveau.
