1. A method for securely transferring multimedia content within a network, the method comprising the computer-implemented steps of:
- providing a main server;
providing a database on the main server that contains registered client systems and corresponding information;
wherein a user selects a set of clients from the database that he wants to share or transfer media between;
wherein the main server creates a digital certificate that identifies the set of clients; and
wherein the digital certificate includes each client'"'"'s serial number and its corresponding public encryption key.

21. A method for preserving coherency of a computer'"'"'s secure cache, the method comprising the computer-implemented steps of:
-
providing a first computer;
providing a second computer;
creating a strong communications key on the first computer;
storing the strong communications key on the first computer;
encrypting the strong communications key using the public key of the second computer;
sending the encrypted strong communications key to the second computer; and
wherein the second computer checks its local cache for an entry from the first computer and, if an entry exists, performs a comparison between a stored encrypted strong communications key in its local cache and the received encrypted strong communications key. - View Dependent Claims (22, 23, 24, 25)

46. An apparatus for preserving coherency of a computer'"'"'s secure cache, comprising:
-
a first computer;
a second computer;
means for creating a strong communications key on the first computer;
means for storing the strong communications key on the first computer;
means for encrypting the strong communications key using the public key of the second computer;
means for sending the encrypted strong communications key to the second computer; and
wherein the second computer checks its local cache for an entry from the first computer and, if an entry exists, performs a comparison between a stored encrypted strong communications key in its local cache and the received encrypted strong communications key. - View Dependent Claims (47, 48, 49, 50)

51. A computer-readable medium carrying one or more sequences of instructions for securely transferring multimedia content within a network, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:
-
providing a main server;
providing a database on the main server that contains registered client systems and corresponding information;
wherein a user selects a set of clients from the database that he wants to share or transfer media between;
wherein the main server creates a digital certificate that identifies the set of clients; and
wherein the digital certificate includes each client'"'"'s serial number and its corresponding public encryption key. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
