Strong encryption is very difficult to defeat and this causes a problem for law enforcement and other government agencies who feel that they have a right to access encrypted communications. In this video, learn about the concept of key escrow and the challenges that key escrow poses to security and privacy.
- [Narrator] Strong encryption is very difficult to defeat,…and this causes a problem for law enforcement…and other government agencies,…who feel that they have a right…to access encrypted communications…under certain circumstances,…such as when they obtain a search warrant.…That's where the concept of key escrow comes into play.…Just like a financial escrow accountant at a bank,…the concept of escrow here means that someone…is holding something,…for use by someone else,…if use for certain conditions are met.…In this case,…government officials have proposed key escrow technologies…that would provide law enforcement with access…to encrypted information.…
The idea is that government agents…would have to obtain a court order…before accessing escrowed keys,…thus protecting the privacy of other individuals.…While this may be a reasonable goal,…there is not yet a reasonable way…to implement this approach in a secure manner.…Perhaps the most concerted effort to deploy…key escrow technology occurred in 1993,…when the government proposed a technology…
