Answer
Transposition Cipher: A transposition cipher does not substitute one symbol for another (as in substitution cipher), but changes the location of these symbols. It reorders (jumbles) the given plain-text to give the cipher-text. They are of two types: Keyed and…
The Diffie-Hellman key exchange (also known as exponential key exchange) is a method for securely exchanging cryptographic keys over an insecure channel. It is a fundamental building block of many secure communication protocols, including SSL/TLS and SSH. The Diffie-Hellman key exchange works…
Clickjacking: Clickjacking is a deceptive technique used by attackers to trick users into clicking on something different from what they perceive they are clicking on, potentially leading to unintended actions. In a clickjacking attack, the attacker overlays a malicious webpage or…
Steps : assume mean dx=x-(assumed mean of x) , dy= y – (assumed mean of y ) prepare an table and calculate summations of x , y , dx , dy , dx^2 , dy^2 , dxdy Now calculate mean…
Regression analysis is a statistical method used to examine the relationship between one or more independent variables (predictors) and a dependent variable (outcome). It aims to understand how changes in the independent variables are associated with changes in the dependent…
