Have Your VoLTE Encryption call with Normal SIM Cards

We provide the VoLTE encryption call solution witiout any support and detecting from carriers, avoiding the  interception from carrier’s network. The solution features 3 types products:  KRC, U-key,  and VoLTE encrypted phone. You only need normal SIM cards to make encrypted calls, directly use the carrier’s VoLTE service without deploying any server 

Ultra Secure Design

Industry-leading IBE E2EE technology, leading ECC 1024bit secret key, completely offline and closed private key generator, key injection is completed through encrypted QR code, and the whole process does not require online operation. Support encryption algorithm customization.

IBE E2EE Technology

Identity based encryption with Leading key strength: 1024-bit private key elliptic curve, more secure than ECC256.

KRC Offline Hardening

The entire process of KRC key generation and registration is offline, the physical port closed. No network security threat

U-key Authentication

Dual authentication by U-key and password to ensure the legitimacy of the operation

Multiple Administrators

Through department configuration, physical-level encryption isolation of departments is achieved

Algorithm Customizd & CIV/CWT

We can provide professional service and SDK for symmetric encryption algorithms customization and CIV/CWT

PQC to be Evolved

Support PQC evolution in future to cope with the upcoming quantum computer cracking

A Secure and Efficient E2EE Private Key Generating solution

Offline design

All private key generation and transmission are done locally offline to avoid network security risks

ECC 1024 bits key

1024-bit private key of elliptic curve, more secure than ECC256.

The KMS - Priavate key generator

KMS is a dedicated private key generation device designed for end-to-end encryption (E2EE), enabling users to quickly and securely generate private key with the encrypted QR code.Only 2 parameters are required, enter your domain and phone number, your encryption key is ready in a second. 

2 types of deployment options to meet different  security level

  • Standard  – Lightweight & Convenient, Works on normal tablet devices, easy to deploy and ready to use
  • KMSPro (Kiosk) – Maximum Security

    • Highly Secured: Physical port lockdown: USB, WiFi, and Bluetooth completely disabled, ensuring zero data leakage
    • System-Level Protection: Locked into the KRC app upon startup, preventing access to other apps or system settings
    • U-Key Dual Authentication: Requires a dedicated U-Key for authorization—when removed, the device locks instantly for enhanced security

The Encrypted phone - ST1

The only model of VoLTE encryption terminal on market without the rely on the  carrier’s  support

ST1 has customization on the modem. It encrypts voice data before in the operator’s VoLTE standard process. Due to the IBE E2EE technology, the success rate and efficiency of encryption establishment are very high.
