Abstract |
In this paper, we have carried out a chosen plaintext attack on Modified Caesar Cipher using Rectangular Method for Enhanced Security. The vulnerabilities and the weaknesses of the target cipher are exploited and the cipher is broken unambiguously. We also proposed modifications to the cipher to make it stronger and more resistant to cryptanalytic attacks. Keywords - Transposition, Diagonal Circular Rotation, Substitution, Chosen Plaintext. | |||||||||
