One-Time Pad Encryption for Launcher Projectile Datalinks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contemporary encryption algorithms, such as conventional public-key encryption, are vulnerable to advances in mathematics and computing technology, and military systems require secure cryptographic implementations that are difficult to reverse-engineer, leading to increased complexity and cost due to the need for anti-tamper hardware.
Innovation Solution
A secure cryptographic system using a one-time pad encryption scheme, where a random number generator in a launcher generates a one-time pad stored in both the launcher and projectile memories, enabling secure wireless communication by encrypting and decrypting data using this pad, with a temporary datalink established during collocation for pad distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional public-key encryption is used, then secure communication can be achieved, but the system becomes vulnerable to quantum computing threats and mathematical advances
Solution Approach 1:
The patent replaces conventional public-key encryption algorithms with a one-time pad encryption system. This substitution eliminates reliance on computational complexity assumptions that are vulnerable to quantum computing, achieving information-theoretic security instead of computational security.
Solution Approach 2:
The system changes the fundamental parameter of cryptographic security from computational hardness assumptions to information-theoretic security guarantees. By using truly random keys that are as long as the message and never reused, the system achieves unbreakable encryption that is immune to quantum computing threats.
2Reliability
If cryptographic implementation details are kept secret, then security is improved, but the system requires anti-tamper hardware increasing complexity and cost
Solution Approach 1:
The patent extracts the cryptographic implementation details from the communication system itself and places them in separate, secure key distribution channels. The one-time pad keys are distributed through physical secure channels or quantum key distribution, separating the encryption mechanism from the key management complexity.
Solution Approach 2:
The system uses multiple copies of the same one-time pad key distributed to both communicating parties through secure channels. This eliminates the need for complex anti-tamper hardware because the security relies on the key distribution process rather than protecting the encryption algorithm implementation.
Data Source
AI summary
The present disclosure provides a system for securing wireless data communication. The system includes a launcher and a projectile. The launcher has a random number generator, a launcher memory, a launcher encryption/decryption module, and a launcher transceiver. The projectile has a projectile memory, a projectile encryption/decryption module, and a projectile transceiver. Both the launcher encryption/decryption module and the projectile encryption/decryption module are configured to use the one-time pad to encrypt and to decrypt data. The system is configured to establish a temporary datalink at a point in time in which the projectile and the launcher are substantially collocated so that the one-time pad can be transmitted from random number generator located in the launcher to the projectile memory using the temporary datalink.
