Design and implementation of secured file delivery protocol using enhanced elliptic curve cryptography for class I and class II transactions

This research study introduces an ID-based identity authentication protocol that utilizes the enhanced elliptic curve digital signature algorithm, a cryptographic method developed on elliptic curve cryptography. The protocol enhances the Consultative Committee for Space Data Systems (CCSDS) File Delivery Protocol (CFDP), a pioneering protocol explicitly defined for distant space communications. This study employs both dependable and uncertain modes of the CFDP protocol. To make more secure data transactions, two key security risks are effectively mitigated in this research as a result of applying the proposed enhanced elliptic curve cryptography algorithm (ECC) over the ternary galois field. First, it thwarts the impersonation of a harmful entity during a passive attack. Second, it prevents masquerade attacks, further reinforcing the security of space data transmission. This ID-based authentication protocol, therefore, offers a significant advancement in protecting far-space communications, optimizing the integrity of data exchanged across vast distances.
