The cost of encryption is not only the economic costs but the cost of the spectrum that you’re using to perform the encryption, and there’s still a minor degradation in encryption. “Encryption was intended for high-security risks, not just day-to-day traffic. ![]() “Encryption was never intended to be a ubiquitous tool that everybody has if everybody’s got it, there no longer is the security element that you want,” Jorgensen said.
