Particular embodiments described herein provide for an electronic device that can be configured to receive untrusted input data at an enclave in an electronic device, isolate the untrusted input data from at least a portion of the enclave, communicate at least a portion of the untrusted data to an integrity verification module using an attestation channel, and receive data integrity verification of the untrusted input data from the integrity verification module. The integrity verification module can perform data integrity attestation functions to verify the untrusted data and the data integrity attestation functions include a data attestation policy and a whitelist.
