Encrypted Data Packet Key Embedding for Wire-Speed Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for secure data transfer are not effective at wire speeds and can be easily identified by unauthorized users due to changes in encrypted data packet formats, which introduces time delays and requires hardware and application changes, limiting their use in L2/L3 layer communication and VPN.
Innovation Solution
A system and method that encrypts data in standard TCP/IP format, including the decryption key at random locations within the encrypted data packets, using AI to ensure the encrypted information is indistinguishable from unencrypted data, allowing for secure transfer at wire speeds without time delays or hardware changes, and supporting L2/L3 layer communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional encryption methods are used with separate key transmission, then security is improved, but transmission speed decreases and time delay is introduced
Solution Approach 1:
The patent merges the encryption key with the encrypted data packet by embedding it within the same transmission unit. This eliminates the need for separate key transmission, thereby maintaining security while achieving wire-speed transmission without the overhead of additional key management communications.
Solution Approach 2:
The encryption key is prepared and embedded within the encrypted packet in advance, before transmission begins. This preliminary integration of the key eliminates real-time key exchange requirements and associated delays, enabling high-speed transmission while maintaining security.
2Reliability
If encryption format is changed to improve security, then unauthorized access is prevented, but packet format compatibility is lost and hardware changes are required
Solution Approach 1:
The patent designs an encryption scheme that works within the universal TCP/IP packet format, making it compatible with existing hardware and software infrastructure. The encryption method is multi-functional, supporting both security requirements and standard network protocol compatibility without requiring specialized hardware modifications.
Solution Approach 2:
The patent changes the parameters of the encryption implementation rather than the fundamental packet format. By modifying encryption parameters and embedding keys within existing packet structures, the system maintains TCP/IP compatibility while achieving enhanced security, avoiding the need for hardware changes.
3Reliability
If random key placement is used to prevent attacks, then security is improved, but key extraction difficulty increases for authorized users
Solution Approach 1:
The patent incorporates feedback mechanisms where the receiver uses previously received packets to decode and extract the embedding key. This feedback loop enables authorized users to efficiently retrieve keys through a systematic process, maintaining ease of operation despite random key placement that enhances security against unauthorized access.
Data Source
AI summary
A system and method for secure transfer of information facilitating transmission of completely encrypted data at wire speeds to/from one or more destinations is associated with authorized one or more users through one or more communication networks. The encrypted information contains a message configured to be concealed from unauthorized access and a decrypting key configured to retrieve the message from the encrypted information, the decrypting key being randomly placed in the encrypted information. The decrypting key accommodated in the encrypted information transmitted at a first time instant is configured to decrypt the message extracted from the encrypted information at a second time instant, the first time instant being followed by the second time instant. The encrypted information pertains to L2 and L3 communication protocols pertaining to standard TCP/IP format, the exchange of encrypted information being facilitated through one or more parallel communication interfaces.
