Bring your own encryption(BYOE), also known asbring your own key(BYOK), is acloud computing securitymodel that allowscloud servicecustomers to use their ownencryption softwareand manage their ownencryptionkeys.[1]BYOE enables cloud service customers to utilize a virtual instance of their encryption software alongside their cloud-hosted business applications to encrypt their data.[2] In this model, hosted business applications are configured to process all data through the encryption software. This software then writes theciphertextversion of the data to the cloud service provider's physicaldata storeand decrypts ciphertext data upon retrieval requests.[3]This approach provides enterprises with control over their keys and the ability to generate their own master key using internalhardware security modules(HSM), which are then transmitted to the cloud provider's HSM.[4] When the data is no longer needed, such as when users discontinue the cloud service, the keys can be deleted, rendering the encrypted data permanently inaccessible. This practice is known ascrypto-shredding.
Potential Advantages
editOrganizations can store data with unique encryption that only they can access.[5] Multiple organizations can share the same hardwareinfrastructurevia cloud services likeAmazon Web Services(AWS) orGoogle Cloudwhile maintaining encryption to comply with regulations such asHIPAA.
Potential Challenges
editResource utilization may be higher compared to traditional encryption practices when multiple users share the same hardware and use their own encryption. Efforts to minimize resource utilization issues may potentially impact security benefits.[6]
