What is the Caesar cipher? The Caesar cipher is one of the simplest and oldest known encryption techniques. It's a type of substitution cipher where each character in the plaintext is shifted a certain number of places down the alphabet. For example, with a shift of 1, 'A' would be en...
In this blog, you will learn about what a cipher is, its types, and examples of the cipher. Also, a Cipher is an algorithm used to encrypt and decrypt data.
The known ciphertext attack, or ciphertext-only attack (COA), is an attack method used in cryptanalysis when the attacker has access to a specific set of ciphertext. However, in this method, the attacker doesn't have access to the corresponding cleartext, i.e., data that is transmitted o...
Ciphertext-only attacksoccur when the attacker only has access to one or more encrypted messages but knows nothing about the plaintext data, the encryption algorithm being used or any data about the cryptographic key being used. This is the type of challenge that intelligence agencies often face ...
Also known asSecret Key Cryptography, private key encryption is where the same key is used by both the sender and the recipient, ensuring secure communication. In this mechanism, the shared key is used to encode the plaintext into ciphertext during transmission. This ciphertext can only be dec...
How Does a Pass the Hash Attack Work? PtH attacks require an understanding of hashes and their usage in IAM systems as well as broader information security practices. A string of information can be transformed into unreadable ciphertext with the help of a mathematical purpose called a hash. A...
Rather than making an irregular IV for each message, this block binding purposes the result of the past block's ciphertext, spreading the word. Moreover, XOR is a reversible activity, which adds one more layer of weakness. The groundwork of BEAST is this consistency. ...
The client and server agree on the version of TLS that will be used to establish a connection. The client and server agree on the cipher suite (or algorithms) that will be used to determine the encryption keys for that session. A TLS certificate is used to verify the identity of the ser...
Least-privilege access is the principle of granting users permission to access only the systems and resources they need for their role. This helps minimize risk to the rest of the network if a user’s credentials are compromised and an unauthorized user attempts to carry out an attack or acces...
Data encryption is a method of converting data from a readable format (plaintext) to an unreadable encoded format (ciphertext). Only after decrypting the encrypted data using the decryption key, the data can be read or processed. In public-key cryptography techniques, there is no need to shar...
