IEEE Security in Storage Working Group
IEEE project for encryption of stored data
The Institute of Electrical and Electronics Engineers (IEEE) Security in Storage Working Group (SISWG), oversees a family of standards for protection of stored data and for the corresponding cryptographic key management. SISWG is part of the IEEE Cybersecurity and Privacy Standards Committee (CPSC).
Block Encryption Standards
SISWG oversees work on the following block encryption standards:
IEEE Std 1619-2025 (Standard for Cryptographic Protection of Data on Block-Oriented Storage Devices) uses the XTS-Advanced Encryption Standard (XEX-based Tweakable Cipher Mode with ciphertext stealing). Examples of its use include self-encrypting storage devices, such as hard disk drives (HDDs) and solid-state drives (SSDs). The XTS-AES algorithm can also be implemented by software-based encryption, with the resulting encrypted user data stored on a drive that does not necessarily perform encryption internally.
The most recent (2025) version of 1619 established requirements for the maximum amount of data to be encrypted using a single symmetric data-encryption key. Earlier versions had pointed out that as larger amounts of data were encrypted with the same key (i.e., the key scope), the higher the chances that an adversary could perform a successful brute-force decryption attack given only the ciphertext (encrypted data). By the early 2020s, SSDs and HDDs had reached such high capacities that such attacks would soon become practical. The impact on self-encrypting drives was that multiple active keys needed to be managed by the drive. There was a similar impact on software-based encryption of large data sets.
Begin with the source’s own compact description: “IEEE Security in Storage Working Group” is iEEE project for encryption of stored data. The dossier treats that line as a proposition to test through IEEE, Security and Storage, not as a finished interpretation.
Why this record matters
The phrase “iEEE project for encryption of stored data” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q10850992. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1619 and 2025.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
