Solution Overview

Problem

Data at rest is vulnerable to unauthorized access during transmission between storage devices due to being decrypted and re-encrypted, leading to increased latency, power consumption, and decreased throughput.

Innovation Solution

Storage devices transmit and store data in encrypted format without decryption, using encryption/decryption keys to ensure secure transfer and storage, reducing unnecessary encryption/decryption processes.

Engineering Contradictions & Design Principles

1Reliability

If data is decrypted and re-encrypted during transmission between storage devices, then data security is maintained, but latency increases and throughput decreases

Engineering Contradiction:

Improvedata securityVSAvoidthroughput

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent introduces an intermediary mechanism where the storage controller preserves the encrypted data state during transmission. Instead of decrypting and re-encrypting, the system uses the existing encryption as a secure intermediary form, eliminating the need for decryption operations while maintaining security.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The encryption operation continues uninterrupted during data transmission. The data remains in encrypted format from the source storage device through the transmission medium to the destination, eliminating the interruptive decryption and re-encryption cycles that would otherwise occur.

Inventive Principle:

Principle #20Continuity of useful action

2Reliability

If data is decrypted and re-encrypted during transmission between storage devices, then data security is maintained, but power consumption increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The encrypted data serves as a secure intermediary that eliminates the need for power-intensive decryption and re-encryption operations. The system leverages the existing encryption state to maintain security without consuming additional energy on cryptographic operations during transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The encryption operation continues uninterrupted during data transmission, eliminating the interruptive decryption and re-encryption cycles that would otherwise consume additional power. The data remains in encrypted format throughout the transmission process.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If data is decrypted and re-encrypted during transmission between storage devices, then data security is maintained, but latency increases

Engineering Contradiction:

Improvedata securityVSAvoidlatency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The encrypted data acts as a secure intermediary that eliminates the need for time-consuming decryption and re-encryption operations. The system preserves the encryption state during transmission, avoiding the temporal overhead of cryptographic operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The encryption operation continues uninterrupted during data transmission, eliminating the interruptive decryption and re-encryption cycles that would otherwise introduce latency. The data remains in encrypted format throughout the transmission process.

Inventive Principle:

Principle #20Continuity of useful action

4Reliability

If data is transmitted in encrypted format without decryption, then transmission security is enhanced, but compatibility issues may arise

Engineering Contradiction:

Improvetransmission securityVSAvoidcompatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The storage controller acts as an intermediary that manages encryption compatibility. It preserves the encrypted data state during transmission while handling key management and encryption protocol coordination between different storage devices, enabling secure transmission without requiring decryption.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary encryption setup and key management before data transmission begins. The storage controller pre-configures encryption parameters and establishes secure communication channels, ensuring compatibility between different storage devices before actual data transfer occurs.

AI summary

A storage device includes: a storage memory component to store requested data in encrypted format; and a storage controller connected to the storage memory component over a storage interface, the storage controller to: receive a command and a decryption override indicator from a host device over a host interface to read the requested data from the storage memory component; retrieve the requested data from the storage memory component in the encrypted format in response to the command; and transmit the requested data in the encrypted format to a destination storage device over a transport layer in response to the decryption override indicator.
