Apparatus and method for encrypting data |
摘要 |
A method for sharing a data set including multiple classifications of security between one or more entities and/or between one or more organizations. Public-keys for use in selectively encrypting the data set with multiple classifications of security are made available in a public-key table. A private-key corresponding to the public-key is used to decrypt the selectively encrypted data set. Public-keys available in the public-key table are re-used to selectively encrypt data sets as appropriate. Public/private-key pairs also may be generated as needed for use in encrypting a document with multiple classifications of security. A single data set may be further encrypted with additional classifications of security as needed. A data set thus may be made available to various entities and/or organizations over a common repository. Symmetric and other encryption techniques also may be used.
