All innovaphone gateways and phones.
Overview
This is an overview of the encryption algorithms that are used in innovaphone products.
SRTP
AES
- Name: Advanced encryption standard
- Type: Symmetric
- Source: Standard algorithm
- Purpose: Voice or media encryption between VOIP endpoints
- Bit strength: 128, 192 or 256 bits
- Key management: A master key is generated using a software PRNG and exchanged using the signalling protocol (H.323, SIPS). Individual keys for data encryption are derived as specified by SRTP standards.
TLS
AES
- Name: Advanced encryption standard
- Type: Symmetric
- Source: Standard algorithm
- Purpose: Encryption of network traffic between TLS endpoints
- Bit strength: 128 or 256 bits
- Key management: During TLS handshake a master key is negotiated between endpoints using asymetric cryptography (see RSA). The master key is based on keying material generated using a software PRNG. Individual keys for data encryption are derived as specified by TLS standards.
3DES
- Name: Triple Data Encryption Standard
- Type: Symmetric
- Source: Standard algorithm
- Purpose: Encryption of network traffic between TLS endpoints
- Bit strength: 168 bits (112 bits effective)
- Key management: During TLS handshake a master key is negotiated between endpoints using asymetric cryptography (see RSA). The master key is based on keying material generated using a software PRNG. Individual keys for data encryption are derived as specified by TLS standards.
