Zigzag Cipher in Cryptography
A transposition cipher that arranges plaintext in a zigzag pattern for encryption.
Understanding Zigzag Cipher
The Zigzag Cipher is a classical transposition cipher that rearranges the plaintext into a zigzag pattern across multiple rows, then reads it row by row to form the ciphertext. It is a simple yet effective method used for encryption, primarily in historical cryptography.
How the Zigzag Cipher Works
Encryption Process
The plaintext is written in a zigzag pattern across a given number of rows.
The text is then read row by row to form the encrypted message.
Decryption Process
The ciphertext is rewritten in the original zigzag pattern.
The text is read in the order it was written to retrieve the plaintext.
Common Uses of Zigzag Cipher
Early military communications.
Basic data obfuscation techniques.
Educational purposes to explain transposition ciphers.
Security Weaknesses
Easily broken using frequency analysis and pattern recognition.
Lack of key complexity, making it unsuitable for modern encryption.
Modern Alternatives
Advanced transposition ciphers with additional complexity.
AES (Advanced Encryption Standard) for secure encryption.
