Security Challenges for CALEA in Voice over Packet Networks

摘要

Security has many new challenges for CALEA in the VoP networks. The major challenges are how to intercept the packets from and to the targeting devices and how to interpret, encrypt, and decrypt them. This paper provides some solutions to the security issues in the VoP networks. There are still unresolved issues that are challenging the VoP vendors, service providers, and law enforcement. That resolution will be the next step needed to move the industry forward.
