> The phone companies standardized on a hopelessly insecure protocol in 1975... I vaguely remember an interview with somebody involved in early ARPANET standardization efforts stating pretty definitively that the prevailing direction for network protocols was source based routing. Anybody who has ever had to write an email address parser has seen vestiges of this (multiple @, ! and : symbols). Supposedly a representative from the NSA helpfully "suggested" they abandon that line of thinking and just mimic the PSTN's approach of trusting the next hop to do the routing. I wonder how accidental it is that SS7 was implemented in such a plainly insecure manner. |
