Claim 7:
8. The method of claim 6, further comprising creating a first group of users comprising:
generating a third public/private key pair;
adding the first user to the first group by computing a second transform key using the third private key and the first augmented public key;
creating a second augmentation factor for the third public key and updating the third public key using the second augmentation factor;
creating an augmented third public key for the group such that any data encrypted to the augmented third public key cannot be decrypted using the third private key;
encrypting data to the augmented third public key;
requesting, via the first device, that data encrypted to the augmented third public key be transformed;
using the second transform key and the second augmentation factor to transform the data encrypted to the augmented third public key so it is encrypted to the augmented first public key;
using the first transform key and the first augmentation factor to transform the data augmented to the first public key so it is encrypted to the second public key, referred to as doubly-transformed data; and
decrypting the doubly transformed data using the second private key.
