MiVoice MX-ONE TLS Workshop

Internet communication via https (http via TLS) has been standard for years and is no longer the exception. TLS serves as an "encryption layer" to protect communication from unintentional eavesdropping. Many other protocols (including SIP) can use this "encryption layer". While the use of TLS is very simple, the configuration is complex and anything but trivial. It requires understanding of asymmetric encryption, hash functions, the RSA cryptosystem, certification authorities, certificate chains, etc.

There are a lot of questions: what needs to be prepared to get a certificate, what exactly is a certificate, how does it work, where do I get it from, what do I get from the certification authority, where do I have to place it, which material is confidential and which not.

This course provides extensive understanding and background knowledge and provides comprehensive answers to the above questions.

Target Group

 The course is designed for technicians in Call Server environments.


ILL or RLL - Hands-On Training

The TLS Workshop provides an equal mix of theoretical delivery and practical demonstrations. Equipment will be available to enable the students to work with the functions listed above.

Key Features

The central component of the course is the understanding of asymmetric encryption, its functionality, possibilities and limitations. It shows exactly what steps are necessary to obtain a certificate and where and how the certificate components are stored and configured in order to enable authentication and encrypted communication.

Using a balanced mix of theory and practical demonstrations, the TLS/SSL Workshop covers the following topics:

  • Basics of Cryptography
  • Terminology
  • Hash, Message Authentication Code, MD5, SHA
  • Symmetric Encryption
  • Asymmetric Encryption
  • Public Key, Private Key
  • Properties and Functionalities of a Key Pair
  • Public Key Infrastructure (PKI)
  • RSA-Cryptosystem
  • Key-Exchange, RSA and Diffie-Hellman
  • From a Key Pair to a Certificate
  • Certificate Signing Request (CSR)
  • Certificate Authority (CA)
  • Certificate Chains
  • Subscriber, Relying Party
  • The X.509 Standard
  • Certificate Formats (PEM, DER, PKCS#7, PKCS#12
  • Encrypted Communication
  • Server- and Client-Authentication
  • SSL/TLS, OpenSSL
  • Useful Tools
