#### Encryption at Rest
* [alpha] Encrypt secrets stored in etcd. For more information, see [Securing a Cluster](https://kubernetes.io/docs/tasks/administer-cluster/securing-a-cluster/) and [Encrypting data at rest](https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/).

#### Node Authorization

- Decoupled `TaintManager` from `NodeLifeCycleController` (KEP-3902). ([#119208](https://github.com/kubernetes/kubernetes/pull/119208), [@atosatto](https://github.com/atosatto))
- Enabled traces for KMSv2 encrypt/decrypt operations. ([#121095](https://github.com/kubernetes/kubernetes/pull/121095), [@aramase](https://github.com/aramase))

- Encryption of API Server at rest configuration now allows the use of wildcards in the list of resources.  For example, *.* can be used to encrypt all resources, including all current and future custom resources. ([#115149](https://github.com/kubernetes/kubernetes/pull/115149), [@nilekhc](https://github.com/nilekhc))

### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

###  Introduced KMS v2

*   KMS: Alpha integration with GCP KMS was removed in favor of a future out-of-process extension point. Discontinue use of the GCP KMS integration and ensure [data has been decrypted](https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/#decrypting-all-data) (or reencrypted with a different provider) before upgrading ([#54759](https://github.com/kubernetes/kubernetes/pull/54759),[ @sakshamsharma](https://github.com/sakshamsharma))
