The RSA Award for Excellence in Mathematics is an accolade presented by the Royal Society for the Encouragement of Arts, Manufactures and Commerce (RSA). The award recognizes outstanding achievements in the field of mathematics, particularly those that have a significant impact on education, innovation, or the application of mathematics in various sectors. The RSA has a long history of promoting learning and development in the arts and sciences, and the mathematics award is part of its broader mission to encourage excellence and foster public interest in these disciplines.
Privilege Management Infrastructure (PMI) refers to a set of technologies and solutions designed to manage and control elevated user privileges in IT environments. PMI is crucial for maintaining security and compliance in organizations by ensuring that users have only the access necessary to perform their job functions and that elevated privileges are granted in a controlled, auditable manner.
Private Set Intersection (PSI) is a cryptographic protocol that allows two or more parties to compute the intersection of their datasets without revealing any additional information about their respective datasets. This means that while the parties can determine which elements are common to both sets, they do not have access to any other data outside of the intersecting elements. ### Key Concepts: 1. **Privacy**: The main goal of PSI is to ensure the privacy of the datasets involved.
PrivateCore is a cybersecurity company that focuses on securing server infrastructure, particularly in cloud environments. Founded in 2012, the company is known for its development of software solutions that help protect against various types of attacks, especially those targeting system memory and virtualization layers. One of the key products developed by PrivateCore is vCage, which is designed to create a secure and isolated environment for running sensitive workloads.
Prince is a lightweight block cipher that was designed for high performance in constrained environments, such as IoT devices and smart cards. It was introduced in 2012 by its creators, who wanted to provide a secure and efficient encryption solution. The cipher uses a structure known as a "substitution-permutation network" and operates on blocks of data.
Polygraphic substitution refers to a type of substitution cipher where groups of letters (or digraphs, trigraphs, etc.) are replaced with other groups of letters. In contrast to simple monoalphabetic ciphers, where each letter is substituted consistently for another single letter, polygraphic substitution takes into account multiple characters at once, which enhances the complexity of the encryption.

Point-to-point encryption (P2PE) is a specific method of data encryption that protects sensitive information, such as payment card data, as it travels between a device, such as a point-of-sale (POS) terminal, and a secure decryption endpoint. The goal of P2PE is to ensure that the data remains encrypted throughout its entire journey, reducing the risk of exposure to data breaches or unauthorized access.
"Pizzino" can refer to different things based on the context. Here are a few possibilities: 1. **Food**: In some regions, "pizzino" may refer to a small pizza or a type of pizza slice, often made as a snack or for individual consumption. It could also describe a specific style or preparation of pizza. 2. **Cultural Reference**: It might refer to a dish or product in a particular culture or cuisine, especially in Italian or Mediterranean contexts.
Philco, originally known as the Philadelphia Storage Battery Company, was an American company founded in the 1890s. Initially focused on battery production, the company diversified into various electronics and consumer products, including radios and televisions. In the mid-20th century, Philco became known for its innovations in electronics, and it expanded into the computer market.
Password strength refers to how difficult it is for an unauthorized party to guess or crack a password. A strong password is essential for protecting personal and sensitive information from cyber threats, such as hacking and unauthorized access. Several factors contribute to password strength, including: 1. **Length**: Longer passwords are generally stronger. A good rule of thumb is to use at least 12 to 16 characters.
Password-based cryptography refers to cryptographic techniques that utilize passwords for the purpose of securing data, authenticating users, or generating cryptographic keys. This method relies on the assumption that the password, which is typically a string of characters created by the user, is known only to that user and serves as a means of encryption or decryption. Here are some key aspects of password-based cryptography: 1. **Key Derivation**: In many systems, passwords are not used directly as encryption keys.
Capture by instead:
sudo wireshark -f http -k
sudo wireshark -f icmp -k
Filter by both protocol and host:
sudo wireshark -f 'host 192.168.1.102 and icmp' -k
For application layer capture filtering, the best you can do is by port:There is an
sudo wireshark -f 'tcp port 80'
http
filter but only for as a wireshark display filterA passphrase is a type of password that typically consists of a sequence of words or a longer string of characters that create a more complex and secure form of authentication. Passphrases are usually longer than traditional passwords, making them more resistant to brute-force attacks. For example, instead of using a single word or a short combination of letters and numbers, a passphrase might be something like "SkyBlueElephantDances123!" or "ToBeOrNotToBeThatIsTheQuestion".
In cryptography, padding is a technique used to ensure that plaintext data conforms to the required length for encryption algorithms, especially block ciphers. Block ciphers operate on fixed-size blocks of data (for instance, 128 bits or 256 bits), and if the plaintext does not fill up a complete block, padding is added to complete it.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
