Open or not open: Are conventional radio access networks more secure and trustworthy than Open-RAN?. (arXiv:2204.12227v1 [cs.CR])

The Open-RAN architecture is a highly promising and future-oriented
architecture. It is intended to open up the radio access network and enable
more innovation and competition in the market. This will lead to RANs for
current 5G networks, but especially for future 6G networks, to move away from
the current centralised, provider-specific 3G RAN architecture and therefore
even better meet the requirements for future RANs. However, the change in
design has also created a drastic shift in the attack surface …
