Three-Pass Protocol Scheme using Gronsfeld and Vigenere Ciphers
Keywords:
Three-Pass Protocol, Gronsfeld, Vigenere, Encryption, Decryption, AlgorithmAbstract
Classical cryptographic algorithms are algorithms that can help users to process encryption and decryption efficiently. Because it is easy, this algorithm is often hacked by wild parties. This algorithm has the power that is vulnerable to attacks on keys. The key used can be hijacked, and finally, the ciphertext can be solved. The plaintext can eventually be found because the key has been taken. The combination of two classical algorithms using the Three-pass Protocol scheme is beneficial because the information sent is stronger because this process does not distribute the key to the recipient of the information. Each actor will do encryption and decryption with their keys. The key will not be exchanged, and the key does not need to be known by the sender and recipient. This scheme is very safe to use because there are no key shipments through the global network. The Three-pass Protocol concept creates a power that is far better than the usual classical cryptographic process.
