```
{
  "[KMSMasterKeyId](#cfn-dynamodb-table-ssespecification-kmsmasterkeyid)" : String,
  "[SSEEnabled](#cfn-dynamodb-table-ssespecification-sseenabled)" : Boolean,
  "[SSEType](#cfn-dynamodb-table-ssespecification-ssetype)" : String
}
```

### YAML
<a name="aws-properties-dynamodb-table-ssespecification-syntax.yaml"></a>

```
  [KMSMasterKeyId](#cfn-dynamodb-table-ssespecification-kmsmasterkeyid): String
  [SSEEnabled](#cfn-dynamodb-table-ssespecification-sseenabled): Boolean
  [SSEType](#cfn-dynamodb-table-ssespecification-ssetype): String
```
