Encrypted File Transfer (AES-256): Secure Data Conduit

In an era of industrial espionage, transferring high-value engineering assets via standard channels is an unacceptable risk. Edelweis employs AES-256 protocols to ensure every TDP—from massive CAD assemblies to sensitive BOMs—is shielded by military-grade cryptography during transit.

1. The AES-256 Encryption Standard

We utilize the same level of security used by government agencies to protect top-secret data:

Computational Immutability
Symmetric key algorithm that would take supercomputers billions of years to crack via brute force.
End-to-End (E2EE)
Data is encrypted at source and only decrypted at destination; unreadable if intercepted mid-transit.
Zero-Knowledge
We do not store decryption keys; only authorized Lead Engineers or Vendors can access the content.

2. Secure Transfer Infrastructure

Feature Implementation Security Objective
TLS 1.3 Tunneling Secure communication layer. Preventing MITM attacks during handshake.
Auto-Expiring Links Time-gated access. Minimizing window of asset exposure.
Integrity Hashing SHA-256 checksums. Verifying file has not been tampered with.
Download Limits Restricted access count. Preventing unauthorized mass-distribution.

3. Integrated Access Control

  • •
    Identity-Linked Access: Shared links require authenticated login via your organization's SSO provider.
  • •
    Recipient Whitelisting: Decryption restricted to pre-approved domains or specific IP addresses.
  • •
    Geo-Fencing Alerts: Real-time notifications for transfers initiated from unrecognized locations or devices.

4. Auditability & Compliance

  • •
    Transfer Logs: Every upload and download event is timestamped and attributed for 100% Traceability.
  • •
    Proof of Delivery: Automated receipts confirming successful receipt and decryption by the manufacturing vendor.
  • •
    Revocation Control: Ability to remotely "kill" access to shared files at any time, even after receipt.

Technical Directives

Directive Protocol
No Email Attachments Standard email attachments are prohibited; all transfers must use secure Vault links.
Key Rotation Encryption keys for project folders are rotated periodically to enhance long-term security.
Local Cache Wipe Temporary files used in encryption are automatically scrubbed from memory following transfer.
