. Introduction Encapsulation security load header provides a hybrid security service in IPv4 and IPv6. ESP can be applied separately, used together with the IP address Authentication Header (AH), or nested, for example, tunnel mode (see "security architecture for the Internet Protocol" [ka97a], the "security architecture document" is used in place below ). Security services can be implemented between one communication host, one communication security

Preface　　 On the forum, I saw many friends who did not know what is the ESP law, what is the scope of application of ESP, what is the principle of ESP law, and how to use the ESP law?

Recently, when I was learning about encryption and decryption and used od for disassembly, I studied compilation again .. In particular, we made an in-depth study on ESP .. The following information is found on the Internet. Let's take a look at it here .. There are many registers in the register, although their functions and use are no different, but in the long-term programming and use, in programmer habits, each register has been assigned a special

I often see the ESP Law in the tutorial. Now I will tell you what the ESP law is. What is its principle? !! (Too useful ◎) BTW: After Reading 18 articles about manual shelling, reading this article may be more helpful to you! 2. Preparations before we begin to discuss the ESP law, I will explain some simple assembly knowledge to you.1. callThis command is a ba

The calculation of TF-IDF values may be involved in the process of text clustering, text categorization, or comparing the similarity of two documents. This is mainly about the Python-based machine learning module and the Open Source tool: Scikit-learn.I hope the article is helpful to you.related articles are as follows: [Python crawler] Selenium get Baidu Encyclopedia tourist attractions infobox message box Python simple implementation of cosine s

The concepts of register ESP and EBP are always confused. View and define esp as the stack top pointer, and EBP as the access Stack pointer. Still cannot be fully understood. Later I used a piece of assembly code to have a clear understanding of the two.The following is the assembly code for calling the test (INT P1, int P2) function according to the call Convention _ stdcall.Suppose that the pre-function S

1. Understand the EBP register There are many registers in the register, although their functions and use are no different, but in the long-term programming and use, in programmer habits, each register has been given a special meaning by default. For example, EAX is generally used for return values, and ECX is used for counting. In the win32 environment, the EBP register is used with the ESP value stored after the call is entered, so that the

very high, and a large number of dimensions are 0, the calculation of the angle of the vector effect is not good. In addition, the large amount of computation makes the vector model almost does not have in the Internet search engine such a massive data set implementation of the feasibility.TF-IDF modelAt present, the TF-IDF model is widely used in real applications such as search engines. The main idea of

Introduction to Web Security--the process of loading and unpacking ESP packets in IPSec transfer modeOne, IPsec(a) introduction Internet Security Protocol ( English:Internet Protocol Security, abbreviated to IPSEC), is to protect the IP Protocol's Network transport Protocol family (a collection of interrelated protocols) by encrypting and authenticating the IP Protocol (Internet Protocol) packet. IPSec consists of two main parts: (1) Establishing a ke

Python TF-IDF computing 100 documents keyword weight1. TF-IDF introduction TF-IDF (Term Frequency-Inverse Document Frequency) is a commonly used weighting technique for information retrieval and Text Mining. TF-IDF is a statistical method used to assess the importance of a word to a document in a collection or corpus.

TF-IDF and its algorithmConceptTF-IDF (term frequency–inverse document frequency) is a commonly used weighted technique for information retrieval and information mining. TF-IDF is a statistical method used to evaluate the importance of a word to one of the files in a set of files or a corpus. the importance of a word increases in proportion to the number of times

The transmission mode is the default IPSec mode for peer-to-peer communication (for example, communication between the client and the server ). When the transmission mode is used, IPSec only encrypts the IP load. The transmission mode protects the IP load through the AH or ESP header. Typical IP load includes TCP segment (including TCP header and TCP segment data), a UDP message (including UDP header and UDP message data) and an ICMP message (includin
