Method and system for providing a public key/secret key pair for encrypting and decrypting data

Abstract

A method for providing a public key/secret key pair for encrypting and decrypting data, wherein the public key of the public key/secret key pair and a master secret key are generated based on predefined policy information, and wherein the secret key of the public key/secret key pair is generated based on the generated master secret key and predefined attribute information. A method for accessing a system in an untrusted environment and a system for providing a public key/secret key pair for encrypting and decrypting data as well as a use for access control are also described.
