摘要

The increasing volume of astronomical data from planetary missions worldwide necessitates secure and efficient encryption techniques to transmit and protect these sensitive data. Traditional RSA-based encryption methods have several computational inefficiencies, and are vulnerable to many present-day attacks, making them less suitable for securing high-dimensional data. This research proposes a Blinded Multi Prime RSA Cryptosystem, integrating multi-prime RSA for computational efficiency and blinded RSA for better security. Blinded Multi Prime RSA achieves a 20–30% reduction in decryption overhead while increasing resistance ( \(\approx 25\%\) ≈ 25 % ) to chosen-ciphertext and factorization attacks compared to its provably secure standalone primitives like the 3-prime RSA, blinded RSA, etc. Further, compared to these methods Blinded Multi Prime RSA also achieved a 23–36% improvement in Decryption-encryption ratio (clock cycles) making it computationally more efficient. This implies the feasibility of the proposed cryptostandard for real-time, secure planetary data encryption, ensuring reliable defense against several cryptographic attacks besides being computationally efficient.
