Various embodiments relate to integrated key revocation with a field loading process and/or related safety and security checks related to an asset system. In an implementation, a data loading request to store a data file via a target storage device of an asset is received. The data file can be signed based on a first key. In response to the data loading request, a key identifier for the first key associated with the data file is compared against (i) a list of key identifiers stored in a key revocation list and (ii) a one-time programmable (OTP) memory of the asset. Additionally, in response to a determination that the data file is successfully authenticated against the key revocation list and the OTP memory, a key revocation process is performed with respect to a second key for the data file associated with the data loading request.
