Which of the following encryption techniques is used by AWS KMS for integration with other AWS services?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer - D.
AWS KMS uses envelope encryption while integrating with other AWS services.
In this encryption technique, data is encrypted by the data encryption key within that service.
This data key is further encrypted using the customer master key (CMK) stored in AWS KMS.
Options A, B & C are incorrect as AWS KMS does not use these encryption techniques for integration with other AWS services.
For more information on AWS KMS, refer to the following URL:
https://aws.amazon.com/kms/features/AWS KMS (Key Management Service) is a fully managed service that makes it easy to create and control encryption keys that are used to encrypt data. It provides a centralized control point for key management and usage, and enables you to encrypt data in a secure and scalable manner.
AWS KMS uses envelope encryption to integrate with other AWS services. Envelope encryption is a technique that involves encrypting data with a data key, which is in turn encrypted with a master key. The data key is used to encrypt the actual data, while the master key is used to encrypt the data key.
By using envelope encryption, AWS KMS ensures that data is protected with strong encryption, while also providing a flexible and scalable way to manage encryption keys. Envelope encryption also enables you to store data in different AWS services, such as Amazon S3, Amazon RDS, and Amazon Redshift, while still maintaining the same level of encryption security.
In summary, the correct answer is D. Envelope Encryption.
