 ### Specifying Encryption key
 
-TODO: Not yet implemented. See section in [L2 Event Bridge Scheduler RFC](https://github.com/aws/aws-cdk-rfcs/blob/master/text/0474-event-bridge-scheduler-l2.md)
+EventBridge Scheduler integrates with AWS Key Management Service (AWS KMS) to encrypt and decrypt your data using an AWS KMS key. 
+EventBridge Scheduler supports two types of KMS keys: AWS owned keys, and customer managed keys.
+
+By default, all events in Scheduler are encrypted with a key that AWS owns and manages. 
+If you wish you can also provide a customer managed key to encrypt and decrypt the payload that your schedule delivers to its target using the `key` property. 
+Target classes will automatically add AWS KMS Decrypt permission to your schedule's execution role permissions policy.
+
+```ts
+declare const key: kms.Key;
+declare const fn: lambda.Function;
+
+const target = new targets.LambdaInvoke(fn, {
+    input: ScheduleTargetInput.fromObject({
+        payload: 'useful',
+    }),
+});
+
+const schedule = new Schedule(this, 'Schedule', {
+    schedule: ScheduleExpression.rate(Duration.minutes(10)),
+    target,
+    key,
+});
+```
