Castle Shield Typhos 3.0 provides users with end-to-end encrypted audio/video capabilities

Castle Shield Holdings announces a major upgrade to its secure messaging app, Typhos. Version 3.0 of Typhos, now includes audio/video calls and audio conference capabilities with end-to-end encryption by default.

In addition to secure audio/video communications, Typhos based on the open source, Linphone, offers a messaging platform that allows consumers and companies to safely communicate in real-time via a user-friendly native mobile messaging app that works on iOS and Android devices. Castle Shield’s secure end-to-end encrypted communications, Typhos platform, provides all preferred means of communication including chat/text, group chat, audio/video calls, and audio group conferencing calling up to 50 participants.

Encrypted, all-the-time, secure Typhos app is an all-in-one communication solution for consumers and companies across multiple market segments including healthcare, finance/banking, legal, telecommunications, etc. Created with security and privacy as the main feature, Typhos is ideal for consumers and companies where convenient confidentiality is not only a priority, but a requirement.

Typhos users do not have to enable end-to-end encryption. All Typhos communications are encrypted by default all-the-time.

The Typhos audio/video functionality includes the following features:

  • High quality audio/video calls
  • Clear audio/video calls with little to no latency
  • Secure communications with end-to-end encryption
  • Fully SIP-based calls
  • Audio conference calls up to 50 participants, including advance calling features
  • Integration with iOS/Android push notifications systems

The audio/video security features include the following:

  • End-to-end encryption for all calls
  • Audio and video encryption with ZRTP and SRTP
  • Audio/Video packets encrypted using AES 256-bit key length
  • Advance ciphering key exchange with ZRTP, including Elliptic Curves Diffie-Hellman (ECDH) X25519 and X448
  • Short Authentication String (SAS) to prevent man-in-the-middle (MitM) attacks
  • Verification of the SIP server authenticity based on x509 certificates
  • Verification of the user identity, using SHA 256 digest authentication

“The key differentiator for Typhos is that all communications are encrypted, all-the-time, whether the data is at rest, in transition, or in motion. Typhos strikes a delicate balance between convenience and security; however, our predominant focus continues to be on keeping data safe and secure. Our focus is not to compete with other popular messaging apps available today. Our goal is to provide the same features with uncompromised security where the user’s data is never used as a means of monetization. Unlike other popular messaging/communications apps, the user and their data are not the product–the security and complete privacy of the user’s data is our product,” said Dr. Milton Mattox, CTO, Castle Shield.

Typhos is available today through the Apple Store and Google Play.
