The invention relates to functional security with a security root and a security chain. A data validator comprising: a first processing circuit configured to perform a first security operation comprising: determining whether first sensor data representative of a second processing circuit factor satisfies a first validation criterion; and executing a first security measure if the first verification criterion is met; and performing a second security measure if the first verification criterion is not met; a second processing circuit configured to perform a second security operation, the second security operation including: determining whether a first value generated by the third processing logic from the sensor data satisfies a second verification criterion; and executing a third security measure if the second verification criterion is met; and executing a fourth security measure if the second verification criterion is not met. 本发明涉及具有安全性根和安全性链的功能安全性。一种数据验证器，包括：第一处理电路，该第一处理电路被配置成用于执行第一安全性操作，该第一安全性操作包括：确定表示第二处理电路
