Two Steps to Get Encrypted Call and Messaging Service

We Innovated 2 Easy-to-use encrypted call and messaging solutions with powerful end-to-endencryption technology – ‘Cypher Call’ and ‘Cypher Box. The Cypher call encrypts your VoLTE/VoNR calls & SMS end to end without deploying any server. The Cypher Box provides a complete private & encrypted instant messaging (IM) with a hand-sized portable box

‘End-to-End Encryption (E2EE) ‘: is a powerful security technology that ensures your private messages/ voice/ data are safeguarded. With E2EE, only you and the recipient have the keys to decrypt the messages. No one else, including the service provider, can access . Your messages are protected from hackers, government surveillance, and other potential threats‘

What is VoLTE

VoLTE, short for Voice over LTE, is a technology that uses 4G or 5G networks to make high-quality voice calls. VoLTE is becoming the global standard for voice calls. It’s widely used by carriers around the world, ensuring a seamless calling experience. Almost all carriers now offer SIM cards that support VoLTE on their 4G/5G networks.

Advanced Algorithm Design

eVoLTE uses theidentity based encryption (IBE) technology and flexible architecture , based on Advanced Sakai–Kasahara Algorithm

Leading key strength: 1024-bit private key elliptic curve, more secure than ECC256.
Efficient algorithm design: One session one key, and in session key negotiation process, no online server (traditional KDC) participation, no extra negotiation communication.
Secure and reliable: Dedicated U-key to ensure security and reliability of operations on KRC, the U-key is handled by trustble administrator.
