Amazon Pinpoint now supports encrypted SNS topics for inbound SMS

Amazon Pinpoint now supports encrypted SNS topics as destinations for incoming SMS text messages. This enables you to add another layer of protection when using Amazon Pinpoint for two-way SMS text messaging. When you enable two-way SMS messaging, you can publish inbound messages to encrypted SNS topics for retrieval and processing. Amazon SNS uses an AWS Key Management Service (AWS KMS) key to encrypt the messages that it sends to these topics.
