Disclosed herein are embodiments related to security in cloudlet environments. In some embodiments, for example, a computing device (e.g., a cloudlet) may include: a trusted execution environment; a Basic Input/Output System (BIOS) to request a Key Encryption Key (KEK) from the trusted execution environment; and a Self-Encrypting Storage (SES) associated with the KEK; wherein the trusted execution environment is to verify the BIOS and provide the KEK to the BIOS subsequent to verification of the BIOS, and the BIOS is to provide the KEK to the SES to unlock the SES for access by the trusted execution environment.
