There is no single best encryption algorithm for both stored data and network traffic. Choose according to what you are protecting and what you need encryption to do: for storage devices, NIST recognizes XTS-AES for confidentiality; for application data that also needs tamper detection, authenticated encryption such as GCM is a better fit; for network traffic, use a maintained TLS implementation configured for your requirements. Plan key management alongside the encryption—not after it.
Start by separating the use cases
“Data at rest” can mean an encrypted disk or block device, storage-layer encryption in a database, or encryption of particular application fields or records. These are not interchangeable. The way data is organized and the security properties you need determine which approach fits.
Storage devices
For block-oriented storage such as a disk, XTS-AES is a NIST-approved option within the specific scope of confidentiality on storage devices. It is not a general recommendation for every stored record, and it does not authenticate the data or its source. If detecting modification matters, account for that separately in the design.
Application data and records
If an application needs both confidentiality and a way to detect tampering, consider an authenticated-encryption mode such as GCM. NIST specifies GCM as authenticated encryption with associated data (AEAD), so it provides a different service profile from XTS-AES. Correct implementation and careful handling of keys and inputs remain essential.

Network traffic
For communication between clients, servers, or services, the practical choice is a maintained TLS implementation and its configuration—not a cipher name used to assemble a custom protocol. Assess protocol-version support, certificate validation, cipher support, interoperability, and any requirements that govern your deployment.
Use this framework to narrow the choice
| Situation | Candidate direction | Critical caveat | Compare before choosing |
|---|---|---|---|
| Block-oriented storage device, such as disk encryption | XTS-AES, within NIST’s storage-device scope (NIST SP 800-38E) | Provides confidentiality; does not authenticate data or its source | Device support, key scope, performance, threat model, and separate integrity controls |
| Application data or records that need confidentiality and tamper detection | Authenticated encryption such as GCM (NIST SP 800-38D) | Depends on correct implementation and key/input handling | Integrity requirements, library or API support, nonce/IV handling, and compliance constraints |
| Client/server or service network traffic | A maintained TLS implementation, configured for the deployment (NIST SP 800-52 Rev. 2) | Do not build a custom protocol from cipher names | TLS versions, certificate validation, cipher support, interoperability, and governing requirements |
This is a selection framework, not a ready-to-deploy configuration. Validate exact parameters against current standards and the library or platform you will use.

Check whether confidentiality is enough
Encryption can keep information from being read without necessarily revealing that someone changed it. That distinction matters when altered data could affect a decision, transaction, configuration, or record. Identify the required security services before comparing algorithm names.
- If the main goal is confidentiality for a storage device: XTS-AES is within NIST’s stated scope, but plan separately for any need to detect modification or establish data origin.
- If the application must detect tampering as well as conceal content: evaluate an authenticated-encryption design such as GCM and verify that the implementation supports the required use.
- If the data is moving over a network: rely on TLS protocol guidance and a maintained implementation rather than selecting a primitive in isolation.
Treat key management as part of the design
An encryption choice is only one part of a workable system. NIST SP 800-57 Part 1 Rev. 5 provides general guidance on cryptographic key management. Define how keys are protected and who can use them, as well as how they are backed up, recovered, and managed through their lifecycle. Make these decisions alongside the encryption architecture so that access and recovery needs do not undermine the protection you intend to provide.

A practical decision sequence
- Locate the data and its path. Decide whether you are protecting a storage device, application records, or network traffic; identify each layer involved.
- Name the security properties. Decide whether confidentiality alone is sufficient or whether the design also needs tamper detection and other controls.
- Choose the matching type of protection. Consider XTS-AES for the NIST storage-device use case, authenticated encryption such as GCM for application data needing integrity, and TLS for transport.
- Evaluate the actual implementation. Check platform and library support, correct parameter and input handling, interoperability, performance needs, and applicable compliance requirements. Do not treat an algorithm name as a complete deployment configuration.
- Specify key operations. Set out key protection, access, backup and recovery, and lifecycle responsibilities as part of the architecture.
- Verify standards and local obligations. Use guidance that applies to your jurisdiction and system, and distinguish final publications from drafts or publications under review.
