The National Institute Of Standards and Technology (NIST) has issued a Broad Agency Announcement (BAA) that solicits products and services that will be used to support this project. Three possible methods of key recovery are depicted in Key Recovery Examples.
KRDP Implementation Evaluation Criteria identify the functional and security concerns related to the Federal governments's need to have emergency access to encrypted data.
The following additional documents may be useful to contracting organizations that are responding to the BAA.
In January 1994, NIST issued "Security Requirements for Cryptographic Modules" as Federal Information Processing Standard (FIPS) 140-1. The standard specifies the security requirements that are to be satisfied by a cryptographic module utilized within a security system protecting unclassified information within computer and telecommunication systems. When applicable, responders to the BAA are asked to provide FIPS 140-1 compliance status for their offered product or service; however, compliance with FIPS 140-1 is not required for participation in this project.
A Certification Authority (CA) system certifies the public key that is part of a public/private key pair that can be used to support data encryption. Vendors of CA systems that are responding to the BAA are asked to state to what extent their product or service complies with the NIST draft "Minimum Interoperability Specification for PKI components" which was issued for public comment in December,1996.
