Copyright © Huawei Technologies Co., Ltd. iii Kunpeng Acceleration Engine Developer Guide（KAE Encryption & Decryption） 1 Overview 1 Overview Kunpeng accelerator engine (KAE) is a hardware acceleration solution based on the Kunpeng 920 processor. It includes KAE encryption and decryption as well as KAEzip, which are used to accelerate SSL/TLS applications and data compression, respectively. Therefore, it can significantly reduce processor consumption and improve the processor efficiency. In addition, the KAE shields the internal processing details from the application layer. Users can quickly migrate services through the standard OpenSSL and zlib interfaces. This document describes KAE encryption and decryption as well as its installation, test procedures, and use cases. KAE Encryption and Decryption The KAE encryption and decryption module uses the Kunpeng hardware acceleration engine to implement the RSA, SM3, SM4, DH, MD5, and AES algorithms. It provides high-performance symmetric and asymmetric encryption/ decryption algorithms based on the lossless user-mode driver framework. Compatible with OpenSSL 1.1.1a and later versions, it supports the synchronous and asynchronous mechanisms. Currently, KAE supports the following algorithms: ● Digest algorithms SM3 and MD5, supporting asynchronous models. ● Symmetric encryption algorithm SM4, supporting asynchronous models and CTR, XTS, CBC, ECB, and OFB modes. ● Symmetric encryption algorithm AES, supporting asynchronous models and ECB, CTR, XTS, and CBC modes. ● Asymmetric algorithm RSA,

  • Package Network Model: a Way to Capture Holistic Structural Features of Open-Source Operating Systems
    S S symmetry Article Package Network Model: A Way to Capture Holistic Structural Features of Open-Source Operating Systems Jing Wang *, Kedi Zhang, Xiaoli Sun, Yusong Tan, Qingbo Wu and Quanyuan Wu College of Computer, National University of Defense Technology, Changsha 410073, China; [email protected] (K.Z.); [email protected] (X.S.); [email protected] (Y.T.); [email protected] (Q.W.); [email protected] (Q.W.) * Correspondence: [email protected] Received: 11 December 2018; Accepted: 29 January 2019; Published: 1 February 2019 Abstract: Open-source software has become a powerful engine for the development of the software industry. Its production mode, which is based on large-scale group collaboration, allows for the rapid and continuous evolution of open-source software on demand. As an important branch of open-source software, open-source operating systems are commonly used in modern service industries such as finance, logistics, education, medical care, e-commerce and tourism, etc. The reliability of these systems is increasingly valued. However, a self-organizing and loosely coupled development approach complicates the structural analysis of open-source operating system software. Traditional methods focus on analysis at the local level. There is a lack of research on the relationship between internal attributes and external overall characteristics. Consequently, conventional methods are difficult to adapt to complex software systems, especially the structural analysis of open-source operating system software. It is therefore of great significance to capture the holistic structure and behavior of the software system. Complex network theory, which is adequate for this task, can make up for the deficiency of traditional software structure evaluation methods that focus only on local structure.

You can install Ubuntu Mate on your old laptop and keep at the same time Windows XP too, if you like XP. Or you can buy a tiny new laptop about 200-300 €/$ and change Windows 10 to Ubuntu. It works! I have made both about three years ago, and I haven't used Windows since then. My own laptop is cheap HP Stream 4 MB/32 GB. When I was studying Ubuntu, I noticed that simple beginner's guide books were not available. So, I did a guide book. I also created a website and named it www.ubuntutor.com. It currently includes Ubuntu 16.04 and 18.04 tutorials. And this guide is third one.
