A New Public-Key Cryptosystem Based on LCD Codes

A cryptosystem is a structure or scheme consisting of set algorithms that converts plaintext to ciphertext encode decode messages securely. The points at computer system employs cryptography. Cryptosystems are classified by the method they use encrypt data. One them symmetric key encryption. While algorithm uses same for encryption and decryption, asymmetric public-key different keys. So it more reliable than cipher algorithm. In this paper, we propose new using LCD codes explain signature protocol based on which reliable.
