Course 5 Lesson 2
This material is based on work supported by the National Science Foundation under Grant No. 0802551 Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author (s) and do not necessarily reflect the views of the National Science Foundation C5L3S1 With the advent of the Internet, social networking, and open communication, a vast amount of information is readily available on the Internet for anyone to access. Despite this trend, computer users need to ensure private or personal communications remain confidential and are viewed only by the intended party. Private information such as a social security numbers, school transcripts, medical histories, tax records, banking, and legal documents should be secure when transmitted online or stored locally. One way to keep data confidential is to encrypt it. Militaries,U the governments, industries, and any organization having a desire to maintain privacy have used encryption techniques to secure information. Encryption helps to boost confidence in the security of online commerce and is necessary for secure transactions. In this lesson, you will review encryption and examine several tools used to encrypt data. You will also learn to encrypt and decrypt data. Anyone who desires to administer computer networks and work with private data must have some familiarity with basic encryption protocols and techniques. C5L3S2 You should know what will be expected of you when you complete this lesson. These expectations are presented as objectives. Objectives are short statements of expectations that tell you what you must be able to do, perform, learn, or adjust after reviewing the lesson. -

CS 255: Intro to Cryptography 1 Introduction 2 End-To-End
Programming Assignment 2 Winter 2021 CS 255: Intro to Cryptography Prof. Dan Boneh Due Monday, March 1st, 11:59pm 1 Introduction In this assignment, you are tasked with implementing a secure and efficient end-to-end encrypted chat client using the Double Ratchet Algorithm, a popular session setup protocol that powers real- world chat systems such as Signal and WhatsApp. As an additional challenge, assume you live in a country with government surveillance. Thereby, all messages sent are required to include the session key encrypted with a fixed public key issued by the government. In your implementation, you will make use of various cryptographic primitives we have discussed in class—notably, key exchange, public key encryption, digital signatures, and authenticated encryption. Because it is ill-advised to implement your own primitives in cryptography, you should use an established library: in this case, the Stanford Javascript Crypto Library (SJCL). We will provide starter code that contains a basic template, which you will be able to fill in to satisfy the functionality and security properties described below. 2 End-to-end Encrypted Chat Client 2.1 Implementation Details Your chat client will use the Double Ratchet Algorithm to provide end-to-end encrypted commu- nications with other clients. To evaluate your messaging client, we will check that two or more instances of your implementation it can communicate with each other properly. We feel that it is best to understand the Double Ratchet Algorithm straight from the source, so we ask that you read Sections 1, 2, and 3 of Signal’s published specification here: https://signal. -

FALL 2020 E-NEWSLETTER at Digital Mountain We Assist Our Clients with Their Computer Forensics, E-Discovery, Cybersecurity and Data Analytics Needs
FALL 2020 E-NEWSLETTER At Digital Mountain we assist our clients with their computer forensics, e-discovery, cybersecurity and data analytics needs. For this E-Newsletter, we focus on ephemeral communications and the affect of disappearing messages on discovery cases. Ephemeral Applications: Digital Trick or Treat The trick in trick or treating is one that has evolved from the neighbor who dons a monster mask when opening the door to the disappearance of peanut butter cups when Dad does the safety check of the night’s candy haul. Our digital communications have gone through an analogous transformation as we first marveled at how much data our devices could hold. Just as we upgraded from a small plastic pumpkin to a pillowcase for larger candy collections - we saved a growing plethora of emails, text messages, digital images, voice messages, and all manner of documents on mobile devices. Now, with the rise of discovery, we want our vulnerable data to disappear as if it were our least favorite candy. Ephemeral applications may be just the trick for that unwanted data. Call It What You Will There is no consensus about what constitutes an ephemeral application beyond the understanding that there is an element of impermanence. In 2016, three Georgia Tech College of Computing researchers proposed the creation of “ephemeral apps” that would allow users to engage with apps on a trial basis that would “pop-up instantaneously” on devices and then disappear after a certain period (https://www.cc.gatech.edu/~kbhardwa/papers/eapps.pdf). At the opposite end of the spectrum, in 2017 fan favorite Snapchat modified its app to allow recipients to determine when photographs and video would disappear rather than the burn after reading settings that propelled Snapchat’s rapid rise (https://www.vox.com/2017/5/9/15595040/snapchat-product-update-limitless-q1-earnings). -

Source code and executables are available on github. The goal of JAMI is to infer ceRNA networks from paired gene and miRNA expression data. The ceRNA hypothesis proposed by Salmena et al. [Salmena2011] suggests that mRNA transcript are in competition over a limited pool of miRNAs they share binding sites for. A competing endogenous RNA is thus a mRNA that excerts regulatory control over the expression of other mRNAs (coding or non-coding genes) via draining them of repressive miRNAs. To quantify the regulatory effect of one gene (the modulator) over another gene (the target) via a specific miRNA, Sumazin et al. [Sumazin2011] proposed the use of conditional mutual information, which was implemented as part of the CUPID software [Chiu2015] implemented in Matlab. -
