The invention provides a vehicle anti-theft verification method, device and system. The method comprises the steps that in response to a received vehicle starting request, an anti-theft slave node generates an original random number sequence and sends the original random number sequence to an anti-theft master node; the anti-theft slave node and the master node respectively generate a first extended random number sequence and a second extended random number sequence; the anti-theft slave node generates a first encryption result; the anti-theft master node judges whether the key is legal or not, if the key is legal, the second extended random number sequence is encrypted through the secret key to generate a second encryption result, and if the key is illegal, the second extended random number sequence is encrypted through the non-secret-key sequence to generate a second encryption result, and specific bytes of the second encryption result are sent to the anti-theft slave node; the anti-theft slave node verifies the corresponding specific bytes of the first encryption result and the second encryption result, if the verification succeeds, the corresponding function is started, and if the verification fails, the corresponding function is not started. According to the invention, anti-theft verification can be realized safely, efficiently and quickly.

    提供了一种车辆防盗校验方法、装置和系统。该方法包括:响应于接收到车辆启动请求,防盗从节点生成原始随机数序列,并将其发送至防盗主节点;防盗从节点和主节点分别生成第一、第二扩展随机数序列;防盗从节点生成第一加密结果;防盗主节点判断钥匙是否合法,如果合法,则利用密钥对第二扩展随机数序列进行加密,生成第二加密结果,如果不合法,则利用非密钥序列对第二扩展随机数序列进行加密,生成第二加密结果,将第二加密结果的特定字节发送至防盗从节点;防盗从节点将第一加密结果与第二加密结果的对应特定字节进行校验,如果校验成功,则启动对应功能,如果校验不成功,则不启动对应功能。本发明可以安全、高效、快速地实现防盗校验。
