Symmetric Encryption with AES-256 CBC

DataShielder HSM PGP uses the AES-256 CBC algorithm to encrypt data with a 256-bit key. Each data block builds on the previous one, which greatly strengthens security by complicating the decryption of individual blocks. Additionally, this method makes unauthorized access much more difficult.

Patented Robust Key Segmentation for Enhanced Security

DataShielder HSM PGP splits the symmetric encryption key into two parts:

• First, Segment 1, a 256-bit key, remains in local browser storage.
• Next, Segment 2, another 256-bit key, stores on an external device like a USB or secure server.

By combining these two parts, the system creates a 512-bit key, which enhances security since the full key is never transmitted. In fact, only when both segments are accessed can the key be reconstituted, further reducing the risk of compromise.

Data Integrity and Hashing with SHA-256

DataShielder HSM PGP uses SHA-256 to create a data fingerprint before encryption. After that, it encrypts the hash alongside the data. As a result, the system can verify during decryption whether the data was altered, ensuring its integrity.

Automation via OpenPGP.js

The OpenPGP.js library implements the cryptographic functions of DataShielder HSM PGP. Compliant with RFC 4880, it ensures interoperability with other PGP systems and supports AES-256, SHA-256, and CBC mode. This library facilitates the management of symmetric keys and encryption/decryption operations according to PGP security standards.

Protection via Volatile Memory

The key segments used for cryptographic operations store in volatile memory for a limited duration (less than a millisecond), minimizing the risk of key compromise during physical or software attacks. This mechanism guarantees that the keys do not remain in memory after cryptographic operations.

Patented Key Segmentation Technology

DataShielder HSM PGP is protected by your international key segmentation patent, which provides a unique approach to key management and authentication. This patent ensures the independence of the two 256-bit key segments. One segment is stored securely in the browser’s localStorage, while the other is kept on an external device, such as a USB, SSD, or NAS drive. The segmentation method ensures that no single location holds the entire key, significantly reducing the risk of compromise.

• Security by Design: The patented segmentation method guarantees that even if one segment is compromised, the full key remains inaccessible without access to the second segment.
• Flexible Key Management: Users can select segments from a variety of storage locations, including local and external devices. This dynamic flexibility in key selection creates numerous secure combinations, ensuring Zero Trust principles are upheld.

Encryption and Decryption with Patented Key Segmentation

The two key segments combine to form a 512-bit key during encryption and decryption, which is then used in AES-GCM. This patented approach strengthens security by ensuring that the key segments remain independent and are never stored together in one place.

Example:

This process, managed by DataShielder Engine, ensures that sensitive information remains protected across various high-risk environments.

Encryption/Decryption

The concatenated 512-bit key is used in AES-GCM for secure handling of data. This method adds an initialization vector (IV) for additional encryption strength.

Example:

• Security by Design: Key segments are never stored together, which ensures that even if one segment is compromised, the other remains inaccessible.
• Enhanced Protection: This method resists both local and network-based attacks since access to both segments is required for successful decryption.

Key Reconstitution

• The segments combine to form the complete 512-bit key.

Data Decryption

• The data decrypts using the AES-256 key and the initialization vector applied during encryption.

Integrity Verification

• The SHA-256 hash recalculates and compares to the original hash. If a difference is detected, the decryption fails, indicating data tampering.

Enhanced Attack Protection

Key segmentation significantly complicates unauthorized access attempts. Even if one segment is compromised, decryption requires both segments, offering heightened protection against both local and remote attacks.

Post-Quantum Resilience

Although AES-256 remains secure, the ability to create a 512-bit key through segmentation enhances resilience against future quantum threats. An attacker must recover and combine two distinct segments before executing a successful attack.

Physical Protection of Segments

Each key segment physically separates, preventing complete compromise in the event of loss or theft of one segment. This mechanism introduces layered defense, especially in sensitive environments requiring increased protection.

Absence of Central Server or Database

The DataShielder HSM PGP system operates offline, without a central server or database. This ensures that keys never store or transmit over insecure public networks, thereby eliminating risks of key compromise through network attacks.

Preparing for Quantum Threats

With the rise of quantum computing, traditional cryptographic algorithms like RSA or ECC will become vulnerable to attacks. The DataShielder HSM PGP system anticipates this threat by adopting key segmentation and integrating robust standards like AES-256 and SHA-256. This approach currently suffices for security, but long-term strategies may consider post-quantum algorithms for enhanced protection against quantum computers.

Transition to Post-Quantum Algorithms

Algorithms such as Kyber (post-quantum encryption) and Dilithium (post-quantum signatures) may incorporate into future versions of the DataShielder HSM PGP to ensure continuous security against evolving technological threats.
