Security Architecture

Multi-layered protection designed for the unique threat landscape of Indian banking infrastructure.

How QuantKawach Prevents Attacks

Comprehensive protection against current and future cryptographic threats

Man-in-the-Middle

Interception of API traffic between banks

Post-quantum authenticated key exchange ensures intercepted data cannot be decrypted

Harvest Now, Decrypt Later

Collection of encrypted data for future quantum decryption

Quantum-resistant algorithms make stored encrypted data permanently secure

Key Compromise

Theft of cryptographic keys

Device-bound keys with hardware security modules prevent extraction

Replay Attacks

Reuse of captured authentication tokens

Timestamp-bound signatures and rotating session keys invalidate replayed requests

Banking Security Model

Principles guiding our security architecture

1

Defense in Depth

Multiple independent security layers ensure no single point of failure

2

Zero Trust Architecture

Every request is authenticated and authorized regardless of network position

3

Cryptographic Agility

Algorithms can be upgraded without service disruption as standards evolve

4

Minimal Attack Surface

Gateway-only deployment limits exposure to a single, hardened component
