In-house control and encrypted voice calls

Cyber Chief Magazine brings you the tactics to uncover and neutralize the insider threat

Cellcrypt announced Cellcrypt Private Switch, a private network that allows an organization’s administrators complete privacy over user identity and calling activity.

This enterprise server software that installs and operates entirely on customer-defined equipment and is administered via a web-accessible management console that only customer-authorized users can access.

Cellcrypt Private Switch consists of a Signaling Server and a web-accessible Management Console. It enables organizations to manage and control a completely private network of devices, users and secure numbers when used in conjunction with Cellcrypt’s Encrypted Content Delivery Network (ECDN), a global network of resilient and secure media servers for carrying secure call traffic and optimizing call performance beyond that which is available using only the public Internet.

The ECDN does not participate in the trust relationship between callers or the end-to-end encryption of the voice call data.

Cellcrypt uses standard encryption technologies including:

  • Advanced Encryption Standard (AES) for symmetric encryption
  • Elliptic Curve Digital Signature Algorithm (ECDSA) for digital signatures
  • Elliptic Curve Diffie-Hellman (ECDH) for key agreement
  • Secure Hash Algorithm (SHA) for message digest

In addition, before these algorithms are processed, Cellcrypt uses additional algorithms for added security (double-wrapping). For example, the voice call is first encrypted using RC4-256 bit and then encrypted again using AES-256 bit.
