NETWORK DEVICE AND DATA DECRYPTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240265119 titled 'NETWORK DEVICE AND DATA DECRYPTION METHOD
The abstract describes a network device with a hardware encryption and decryption circuit and a one-time programmable storage area, used to decrypt files.
- The network device includes a chip with hardware encryption and decryption capabilities.
- The chip has a one-time programmable storage area for storing sensitive information.
- A receiver on the device is used to receive encrypted files for decryption.
- The hardware circuit retrieves a root key plaintext from the storage area to decrypt the ciphertext.
- The decrypted file is obtained as plaintext after decryption.
Potential Applications: - Secure file transfer and communication - Data protection in network environments - Secure storage of sensitive information
Problems Solved: - Ensuring secure transmission and storage of encrypted files - Protecting sensitive data from unauthorized access
Benefits: - Enhanced security for data transfer - Protection of sensitive information - Efficient decryption process
Commercial Applications: Title: Secure Data Transfer Solutions This technology can be used in industries such as cybersecurity, finance, and healthcare for secure data transfer and storage, ensuring the protection of sensitive information.
Questions about the technology: 1. How does the hardware encryption and decryption circuit enhance data security? - The hardware circuit ensures that sensitive information is securely decrypted using a root key stored in a one-time programmable area, reducing the risk of unauthorized access. 2. What are the potential drawbacks of using a one-time programmable storage area for storing encryption keys? - One potential drawback is the inability to change the stored key, which may pose a challenge if the key is compromised.
Original Abstract Submitted
in accordance with an embodiment, a network device includes a chip including a hardware encryption and decryption circuit and a one-time programmable (otp) storage area; and a receiver configured to receive a to-be-decrypted file, where the to-be-decrypted file comprises a ciphertext. the hardware encryption and decryption circuit is configured to obtain a root key plaintext from the otp storage area, and decrypt the ciphertext using the root key plaintext to obtain a plaintext
