It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL). -

Authentication in the Mesh with Webassembly
Authentication in the mesh with WebAssembly Sondre Halvorsen Master’s Thesis, Spring 2021 Thesis submitted for the degree of Master in Informatics: programming and system architecture 30 credits Department of Informatics Faculty of mathematics and natural sciences UNIVERSITY OF OSLO Spring 2021 © 2021 Sondre Halvorsen Master Thesis http://www.duo.uio.no/ Printed: Reprosentralen, University of Oslo Abstract At the start of the last decade Marc Andreessen stated in his now famous blog entry; ‘Software is eating the world’ [173], and as software is eating the world, problems stemming from its security, or lack thereof, is eating it as well. Or- ganisations are increasingly moving to the cloud and adopting new architecture patterns in this new environment, such as cloud native and microservice ar- chitecture. While moving to the cloud generally results in better security for organisations, due to large professional platforms, microservice architectures in- troduce some new problems in regards to cross-cutting concerns like security, robustness and observabiltity. Service mesh is a technology that aims to provide cloud native and application agnostic solution to many of the challenges with micro service architectures. In parallel with the cloud native revolution there has been innovations in areas like security as well. Authentication, authoriza- tion, and access control have changed drastically, with new requirements for how users want to manage and use their identity. Zero Trust Architectures is an example of this drawn to its logical conclusion where no connection is trusted by default. Unfortunately security breaches stemming from poor implementation of security protocols and frameworks rank among the highest still. -

Enriched Content: Concept, Architecture, Implementation, and Applications
Enriched Content: Concept, Architecture, Implementation, and Applications by Hung-Hsien Chang A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Computer Science New York University May, 2003 Professor Ken Perlin c Hung-Hsien Chang All Rights Reserved, 2003 ii Dedication To my parents, for their extreme patience and supports. To Ya-Ya, for its “understanding”. iii Acknowledgements It has been a long journey. A page or two of descriptions do not do justice to the people who have assisted me over the years; however, that is why they call such thanks an acknowledgement. For New York University, I thank my advisor Ken Perlin who have given valu- able guidance at critical moments, over the years he showed me his fun computer graphics demo and we shared a few child-like geeky moments, and of course not to mention the influence of his more incurable optimism (I thought I was incurably optimistic.) My reader committee have been supportive: Alan Siegel who has pa- tiently and constantly given me advice on both academics and life, Ernest Davis whose “extreme” encouragement and enthusiasm are crucial while his scrutinizing my work kept me on my toes. My other two thesis committee members are gener- ous and understanding, to say the least. Richard Cole, who I believe, is surprised to see my change, and Dennis Shasha is enduring to my ever changing mind in the last minute. I also thank Chee Yap, Ricky Pollack, Ravi Boppana, Dan Melamed, David Geiger, Ben Goldberg, Bud Mishra, Joe Spencer, late Robert Paige, Arthur Gold- berg, Jack Schwartz, Eero Simoncelli, Zvi Kedam, Dennis Zorin, Victor Schwartz, Vasilis Vassalos, and Deborah Weichenberg. -
