IACR Cryptology ePrint Archive · Breaking the IEEE Encryption Standard – XCB-AES in Two QueriesTweakable enciphering modes (TEMs) provide security in various storage and space-critical applications, including disk and file-based encryption and packet-based communication protocols. XCB-AES (originally introduced as XCBv2) is specified in the IEEE 1619.2 standard for encryption of sector-oriented storage media and comes with a formal security proof for block-aligned messages. In this work, we present the first plaintext recovery attack on XCB-AES $-$ the shared difference attack, demonstrating that the security of XCB-AES is fundamentally flawed. Our plaintext recovery attack is highly efficient and requires only two queries (one enciphering and one deciphering), breaking the claimed $\mathsf{vil\text{-}stprp}$, $\mathsf{stprp}$ as well as the basic $\mathsf{sprp}$ security. Our shared difference attack exploits an inherent property of polynomial hash functions called separability. We pinpoint the exact flaw in the security proof of XCB-AES, which arises from the separability of polynomial hash functions. We show that this vulnerability in the XCB design strategy has gone unnoticed for over 20 years and has been inadvertently replicated in many XCB-style TEM designs, including the IEEE 1619.2 standard XCB-AES. We also apply the shared difference attack to other TEMs based on XCB $-$ XCBv1, HCI, and MXCB, invalidating all of their security claims, and discuss some immediate countermeasures. Our findings are the first to highlight the need to reassess the present IEEE 1619.2 standard as well as the security and potential deployments of XCB-style TEMs.

#DIN #Spec 91526 released on #Knowledge #Graphs for #Language models and vice versa: Hybrid applications of #symbolic and sub-symbolic #AI

The #standardization focuses on the advantages of hybrid approaches that combine symbolic knowledge with modern language models.

Metabarcoding and MetagenomicsWhat is eDNA method standardisation and why do we need it?The rapid advancement of environmental DNA (eDNA) science in the past two decades has inspired a concomitant growth in the development of eDNA sampling and analytical methods. However, these methods are often developed by individual laboratories or institutions, which can isolate protocols within programmes, agencies or regions and prevent the beneficial exchange of data and ideas. Recent efforts to advance national and international coordination have resulted in a groundswell of standardisation efforts, but there is still considerable confusion around the role of formal standards for regulatory or research applications. With this commentary, we hope to provide clarity on the terminology used in standardisation discussions, including the differences between formal standards and best practice guidelines. Additionally, we discuss how eDNA method choice may be informed by environmental management scenarios and review examples of formal eDNA method standards being used to inform management action. The eDNA community now has an opportunity to develop a roadmap for method development to help close standardisation gaps, advance eDNA method adoption and accelerate our ability to monitor biological life at the scales our current environmental challenges demand.

At tomorrow's Cyberbreakfast "Data Ecosystems", #NFDI Director York Sure-Vetter will give an introduction to the important role of standardisation in research data management and how NFDI is working to connect data spaces from science and industry.
