Encrypted Channel

ART enables highly secure peer-to-peer messaging through its Encrypted Channels feature. This functionality ensures that messages exchanged directly between communicating parties remain confidential by leveraging robust cryptographic methods. Encrypted Channels are ideal for applications where data privacy and communication integrity are paramount.

How It Works​

Encrypted Channels implement a layered security approach to protect data during transmission, even in untrusted environments.

1. Secure Key Exchange​

The foundation of secure communication is a shared secret key, established without ever being transmitted over the network:

  • Secure Key Generation: ART utilizes ECDH(Elliptic Curve Diffie-Hellman) a secure key exchange algorithm to establish a shared secret between communicating parties. This process ensures that a unique key is generated and agreed upon by both sides, without the key itself ever being transmitted over the network.
  • Confidentiality Principle: This shared secret forms the basis for encrypting all subsequent communications. Even if an unauthorized entity or interceptor intercepts public key, they cannot derive the confidential encryption key without the corresponding private components from both parties.

2. Message Encryption​

Once the secure shared secret is established, messages are encrypted and authenticated using a highly reliable cryptographic mechanism:

  • Data Encryption & Integrity: ART uses strong cryptography to encrypt and decrypt messages. This cryptographic process not only encrypts the message content but also integrates authentication tags. These tags ensure data integrity, meaning any unauthorized alteration or tampering with the message during transmission is immediately detected by the recipient.

3. Peer-to-Peer Communication​

Encrypted Channels inherently facilitate direct, end-to-end encrypted communication:

  • Direct, Encrypted Pathways: This feature enables direct communication between peers, eliminating the need for intermediaries to handle decryption or re-encryption. Messages are encrypted at the sender's end and decrypted only at the receiver's end.
  • Real-Time Confidentiality: Encrypted Channels are particularly valuable for applications demanding real-time, confidential messaging, where patient privacy, financial security, or sensitive corporate data are involved.
Important

We empower our clients with complete control over their security. Clients are solely responsible for maintaining their secret keys, as ART doesn't provide any key storage or management services.

Benefits for Data Protection and Privacy​

The implementation of Encrypted Channels provides critical advantages for your application's security posture:

  • Guaranteed Confidentiality: Messages remain private and readable only by the intended communicating parties.
  • Ensured Message Integrity: Protection against tampering ensures that messages arrive exactly as they were sent.
  • Enhanced Data Privacy: Critical for sensitive data exchanges, meeting stringent privacy requirements and compliance standards.
  • Robust Against Eavesdropping: The secure key exchange and strong encryption make it highly resistant to unauthorized interception.

Common Use Cases​

Encrypted Channels are ideal for scenarios where secure, private communication is essential. Common use cases include:

  • Private Messaging: Secure one-on-one chat applications where users exchange sensitive information.
  • Financial Transactions: Secure communication for banking apps, payment processing, or any financial data exchange
  • Healthcare Communication: Protecting patient data in telemedicine or health information systems.
  • Confidential Business Communication: Secure channels for corporate messaging, legal consultations, or any scenario requiring strict confidentiality.
