Abstract

The well-known multi-letter encryption cipher is Playfair cipher although a wide variety of techniques have been employed for encryption and decryption. The Playfair cipher shows a great advancement over other encryption methods. This cipher technique is used for encrypting and decrypting the pair of characters together. This paper proposes an idea to solve the traditional Playfair cipher through parallel algorithm in order to encrypt the given message. A key is used to encrypt the message. The idea is to reduce the time complexity of sequential Playfair cipher by parallelizing it and using the power of GPUs to the maximum. Instead of making one process do the encryption, a number of threads are used to encrypt letters simultaneously. This is achieved using CUDA.
