Key escrow system

In a public key encryption system, there may be instances where someone other than the communicating parties needs access to encrypted data. A key escrow system is one way such access might be obtained. A key escrow system would hold the key needed to decrypt an encrypted transmission in "escrow." Such a system could be maintained by a private organization or the government, and anyone seeking access to an encrypted transmission would have to demonstrate their need for the key through a process, such as obtaining a search warrant, that ensures the legitimate privacy and security needs of users of encrypted transmissions.
