Cryptographic Backdoors Explained

Backdoors are usually inserted into a program or algorithm before it is distributed widely. They are often hidden in part of the design of the program or algorithm. In cryptography specifically, a backdoor would allow an intruder to access the encrypted information without having the correct credentials.

What is an encryption backdoor?

A backdoor is a built-in way of circumventing that type of encryption. It essentially allows a manufacturer to access all the data on any device it creates. And it's nothing new—this reaches all the way back to the abandoned “Clipper chip” in the early '90s. Many things can serve as a backdoor.

What is meant by backdoor?

A backdoor refers to any method by which authorized and unauthorized users are able to get around normal security measures and gain high level user access (aka root access) on a computer system, network or software application.

What is backdoor Trojan?

What is the purpose of a key escrow?

Key escrow is a method of storing important cryptographic keys. Each key stored in an escrow system is tied to the original user and subsequently encrypted for security purposes. Much like a valet or coat check, each key is stored in relation to the user that leverages it, and then returned once queried.
