VM Initialization Data Decryption for Secure Cloud Boot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for protecting user data during virtual machine initialization in cloud environments are inadequate, as plaintext user data is easily accessible and vulnerable to unauthorized access and tampering during the initialization process.
Innovation Solution
Encrypting user data using a public/private cryptographic key pair, either manually by the user or automatically by the cloud provider, and decrypting the data within the virtual machine using the corresponding private key to ensure secure data handling throughout the initialization process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If user data is stored in plaintext during virtual machine initialization, then data processing speed is improved, but data security deteriorates
Solution Approach 1:
The system performs preliminary encryption of user data before the virtual machine initialization process begins. The encryption operation is executed in advance using a public key, transforming the plaintext data into encrypted format before it is stored or processed during initialization, thereby preventing unauthorized access while maintaining processing efficiency through automated key-based encryption.
2Object-affected harmful factors
If user data is encrypted before virtual machine initialization, then data security is improved, but initialization complexity increases
Solution Approach 1:
The virtual machine initialization system performs self-service encryption automatically using public key infrastructure. The system retrieves the user's public key and encrypts the data autonomously during the initialization process, eliminating the need for manual encryption operations and reducing the complexity burden on users while maintaining strong security.
Solution Approach 2:
The system introduces a cryptographic key management intermediary that handles the encryption and decryption operations. This intermediary component manages the public/private key pairs and facilitates secure data transfer during initialization, abstracting the complexity of encryption operations from the user and simplifying the overall initialization process.
3Object-affected harmful factors
If manual encryption is performed by the user, then data security control is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables users to maintain control over their data security through self-service encryption using their own private keys. Users can encrypt their data locally before upload or configure encryption settings in the cloud console, maintaining security control without requiring complex manual intervention during the actual initialization process.
Solution Approach 2:
The system provides feedback mechanisms that guide users through the encryption process. The cloud platform detects whether data is already encrypted and provides appropriate responses or warnings, automatically handling encrypted data while guiding users through simple encryption steps when needed, thereby maintaining ease of operation while preserving security control.

AI summary
User data security is provided. Encrypted user data are identified in a virtual machine. A private key of a public/private cryptographic key pair corresponding to a user is retrieved. The encrypted user data is decrypted within the virtual machine utilizing the private key corresponding to the user to form decrypted user data. The encrypted user data are replaced in the virtual machine with the decrypted user data. The decrypted user data is processed in the virtual machine to perform a service in a cloud environment.
