Key aggregate cryptosystem for scalable data sharing in cloud storage
This document proposes a key-aggregate cryptosystem (KAC) to securely and efficiently share data in cloud storage. KAC allows data owners to generate constant-sized decryption keys that delegate access to any subset of encrypted files, without increasing key size. It describes the existing approaches that encrypt data before uploading but have increasing costs as more decryption keys are shared. The proposed KAC system uses a special public-key encryption technique that produces constant-sized aggregate decryption keys that can decrypt any ciphertext associated with attribute classes contained in the key. It outlines the authentication, encryption, sharing, and decryption modules and concludes that KAC provides a more flexible delegation method compared to hierarchical key assignment.
key aggregate cryptosystem for scalable data sharing in cloud
The document proposes a new key-aggregate cryptosystem (KAC) for secure and efficient data sharing in cloud storage. KAC allows encrypting data under a public key and identifier, and extracting an aggregate secret key from a master secret key. The aggregate key is compact yet provides decryption power for any subset of ciphertexts. This allows flexible delegation of decryption rights by sending a constant-sized aggregate key for sharing encrypted data on cloud storage. Formal security analysis is provided for the cryptosystem in the standard model.

The document proposes protocols for secure launch of virtual machines (VMs) in Infrastructure as a Service (IaaS) clouds. This would provide cloud tenants assurance that their VM instances were launched on hosts with expected software stacks. Currently, cloud tenants have limited control over security mechanisms and lack symbols confirming the integrity of their VM hosts. The proposed protocols aim to address this by verifying platform integrity for hosts and giving tenants symbols of expected code stacks for their launched VMs.

Identity based secure distributed data storage schemes
This document proposes two identity-based secure distributed data storage schemes. The first scheme is secure against chosen plaintext attacks, while the second is secure against chosen ciphertext attacks. Both schemes allow a file owner to independently set access permissions and prevent unauthorized access or modification of outsourced files by proxy servers. The proposed schemes were designed to address confidentiality and integrity issues with existing distributed data storage systems by incorporating identity-based cryptography and access control set by the file owner.
KeyD: Secure Key-Deduplication with Identity-Based Broadcast Encryption
In this paper, we design a novel client-side deduplication protocol named KeyD without such an independent key management server by utilizing the identity-based broadcast encryption (IBBE) technique.
Users only interact with the cloud service provider (CSP) during the process of data upload and download.
Security analysis demonstrates that KeyD ensures data confidentiality and convergent key security, and well protects the ownership privacy simultaneously

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Safelyio Toolbox Talk Softwate & App (How To Digitize Safety Meetings)
Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Superpower Your Apache Kafka Applications Development with Complementary Open...
Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 )
Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!
