In the next ten years, the notion of quantum supremacy will have likely been attained, and further, quantum computing will have begun to crack data encryption of the prolific types in use today. Ten years. Who knows of this impending shift from “security” to seemingly instant “insecurity”? Even data encrypted today, last week, 3 years ago, etc., will be vulnerable to decryption. Is anyone listening? Ten years, if predictions hold firm. There are some industry leaders – IBM, for one – which believe the time before quantum supremacy and its deleterious effects upon encryption are a mere 5 years in the offing. This piece explains the concept of cryptographic agility and why we, as a society, must get moving to switch to post-quantum cryptographic methods.
