Let’s take a closer look at AWS DynamoDB encryption in transit. Bobcares, as a part of our AWS Support Services offers solutions to every query that comes our way.

AWS DynamoDB encryption

Amazon DynamoDB offers a highly reliable storage infrastructure that is ideal for mission-critical and primary data storage. In an Amazon DynamoDB Region, data is redundantly stored on multiple devices spread across multiple facilities.

DynamoDB protects both user data at rest and data in transit between on-premises clients and DynamoDB, as well as between DynamoDB and other AWS resources in the same AWS Region. Implementation of DynamoDB encryption is for:

• Data at rest
• Data in transit
• Data in use

In this article, we will explore the AWS DynamoDB encryption in transit.

AWS DynamoDB encryption in transit

Encrypting the sensitive data while it transfers to and from DynamoDB is the data in transit encryption. It ensures that no third party, including AWS, has access to the plaintext data. The DynamoDB encryption client, a software library, will encrypt data in transit. The encryption client is free under the Apache 2.0 license.

When the user adds items to the table, the DynamoDB encryption client will allow the user to encrypt and sign them. It also allows users to verify and decrypt the data once it has been recovered. Client-side encryption is another name for this mechanism. It supports the majority of Amazon DynamoDB’s features, including global tables; however, older versions of global tables may require us to change some configurations before we can use the encryption client.

The DynamoDB encryption client enables secure implementations that use a unique encryption key to encrypt the attribute values within each item in a table. Furthermore, by signing the items, we will be able to protect against unauthorized changes; unauthorized changes include deleting or adding attributes or swapping encrypted values.

When using the DynamoDB Client, we can use encryption keys from a variety of sources, including custom cryptography services such as AWS CloudHSM or AWS Key Management Service (AWS KMS).

Currently, DynamoDB encryption client libraries are available in Java and Python. The various programming languages used to implement it are interoperable, which means we can encrypt data with the Java client and decrypt it with the Python client.

The DynamoDB Encryption Client, on the other hand, is incompatible with the AWS Encryption SDK and the Amazon S3 Encryption Client. As a result, we can’t encrypt with one client-side library while decrypting with another.

Conclusion

AWS DynamoDB encryption provides a highly reliable storage infrastructure designed for mission-critical and primary data storage. It also provides security for data at rest and data in transit. In this article, we have provided the relevant details from our Tech team on AWS DynamoDB encryption.
