NCSC Releases Post-Quantum Cryptography Timeline

The document is an opinionated analysis of security models, arguing against crypto backdoors and client/device-side scanning while promoting segregation of plaintext from communications devices (e.g., offline endpoints and OTP). It contrasts “Swiss cheese” with defense-in-depth, and highlights side-channel and EMSEC concerns such as TEMPEST/Van Eck risks and pervasive MEMS-based surveillance, noting that legacy, segregated hardware can mitigate many modern threats.
