End-to-End, Quantum-Safe Cryptography with Mutual Authentication
​​Cellcrypt redefines Secure Communications, offering a cryptographic solution designed to surpass the most demanding international security standards.
With a focus on comprehensive, end-to-end cryptography, the application employs advanced encryption layers and cutting-edge key agreement protocols that exceed conventional security practices.
When two Cellcrypt devices connect, they establish a highly secure, encrypted channel. This channel uses unique session keys and a combination of classical and post-quantum cryptography to protect your calls from eavesdropping and your data from interception.
Every communication verifies the identity of both parties, ensuring that only authorised individuals can access sensitive information.

Multi-Layer Encryption
1. TLS / SRTP Encrypted Tunnels
At the network layer, data transmission occurs through secure, mutually authenticated TLS-encrypted tunnels, and all media transmission occurs through SRTP-encrypted tunnels that have been certified to protect data at the highest classification levels.
While most secure communication solutions only provide this level of protection, the true strength of Cellcrypt lies in its end-to-end encryption and quantum-safe features, all operating within this secure TLS/SRTP framework.​

3. Post-Quantum Protection
As the final safeguard, our Classical Cryptography is reinforced with Post-Quantum Protection (PQP). This ensures that communications remain secure even against future quantum computing threats, including "harvest now, decrypt later" attacks.
The PQP layer is designed with flexibility in mind, allowing seamless updates and the integration of new algorithms as global standards evolve, without compromising the integrity of the existing encryption.
2. Classical Cryptography Suite
At the application software layer, data is secured end-to-end using a robust combination of Elliptic Curve Cryptography (ECC) and Symmetric-Key Cryptography.
Cellcrypt employs dual (static+dynamic) ECDH key derivation (P-521) for secure key establishment and dual symmetric key encryption (AES-256 + ChaCha20-256).
This adaptable suite complies with diverse governmental encryption standards, making it a versatile solution for securing highly sensitive communications across various operational contexts.

4. True Zero-Trust Security
Cellcrypt is founded on the principle that all network infrastructure operates under a Zero-Trust model, assuming it may be compromised or deliberately targeted.
By harnessing both Classical and Post-Quantum Cryptography, Cellcrypt effectively neutralises the risks associated with compromised environments.
This architecture guarantees the highest level of security, delivering unparalleled protection and confidence for communications, even in the most hostile and demanding conditions
