Silvio Micali, the professor, holds one patent that he says covers a critical part of the government's Clipper project.
Micali says that his patent covers the basic notion of escrowed keys in which trustees are given guaranteed pieces of the key.
Micali won't say what sum he is seeking from the government except that it is reasonable compared to standard practices.

 John Templeton Foundation: Participants
He is widely acknowledged as the creator of the algorithmic theory of pseudorandomness, and his invention of zero-knowledge and interactive proofs was recognized by the 1993 Gödel Prize, the highest award in theoretical computer science.
Born in Palermo, Italy, Dr. Micali studied mathematics at the University of Rome before coming to the United States for graduate work at the University of California at Berkeley, where he took his Ph.D. in computer science in 1982 under the supervision of Manuel Blum.
Micali is the editor (with Franco Preparata, Paris Kanellakis, Christoff Hoffmann, and Robert Hawkins) of a five-volume series of textbooks, Advances in Computing Research (JAI Press, 1984-1993), and has published more than one hundred scientific papers.

 PATENT AGREEMENT REMOVES PERCEIVED BARRIER TO TELECOMMUNICATIONS SECURITY SYSTEM   (Site not responding. Last check: 2007-10-23)
Micali's inventions refer to the process by which a digital "key" is divided into components, safeguarded by separate agents and combined when legally authorized in order to decode the communication of someone suspected of criminal activity.
This license agreement eliminates concerns Micali raised about possible infringement of his patents in key escrow encryption.
The agreement in principle grants the government non-exclusive licenses to Micali's patented inventions for current implementations of the escrowed key process -- including those generally known as Clipper and Capstone technologies -- and for future implementations that may be developed using those inventions.

Micali confirmed that he has been negotiating with Michael Rubin, an attorney at the government's National Institute of Standards and Technology, over royalties for his technology.
I believe we can have some trust in the government." Micali says he invented the notion of breaking the key to an encrypted message into two parts and entrusting those parts with a trustee or agent.
Micali says he prefers a bottoms-up approach rather than the top-down government solution.

 Mass High Tech
Micali believes that the discoveries these patents cover will pave the way for a less expensive security permissions system that can be distributed over public networks and yet doesn’t depend on connecting back to a central authority for approvals.
Patents in hand, Micali founded NovoModo in 2001, a three-person company that, last August, merged with CoreStreet, an experienced group of 13 Java programmers who were looking for their next gig.
Hussey claims that Micali’s patented algorithms enable CoreStreet to deliver multiple permissions for a single user to any secured system — including security doors, vehicles with hazardous cargo and critical data assets — in chunks as small as 20 bytes.

- Showing (together with Silvio Micali and Avi Wigderson) how to construct zero-knowledge proof systems for NP: Zero-knowledge proofs are probabilistic and interactive proofs that efficiently demonstrate the validity of an assertion without conveying any additional knowledge.
- Showing (together with Shafi Goldwasser and Silvio Micali) how to construct pseudorandom functions: Extending the notion of pseudorandomness to functions, it is shown how to construct pseudorandom functions, using an arbitrary pseudorandom (bit) generator.
This means that a fl box that stores only k secret bits can implement a function from k bit strings to k bit strings that cannot be distinguished from a random function by any poly(k)-time observer that can ``query'' the function on arguments of its choice.

 GMR (cryptography) - Wikipedia, the free encyclopedia
In cryptography, GMR is a digital signature algorithm named after its inventors Shafi Goldwasser, Silvio Micali and Ron Rivest.
In contrast to RSA, GMR is secure against adaptive chosen-message attacks — even when an attacker receives signatures for messages of his choice, this does not allow him to forge a signature for a single additional message.

Recently, systems have been developed by which a secret decryption key is in the hands of several trustees, so that each trustee holds a guaranteed piece of the key, while he cannot predict the full key.
We want to develop such a system in a public key setting so that the secret key that is guaranteed to be shared among some trustees is the secret decryption key corresponding to a given public encryption key.

Refer to the paper "Micropayments Revisited" written by Silvio Micali and Ron Rivest: http://theory.lcs.mit.edu/~rivest/publications.html [The powerpoint slides are also quite useful.] The schemes in this paper combine Payword (Rivest and Shamir) with the Lottery Ticket proposal (Rivest).
As of the last time I talked to Ron and Silvio about it, the Peppercoin scheme is based on these techniques.

Most of the contents of this paper is covered in Chapter 4 of Foundations of Cryptography - Fragments of a Book [by Oded Goldreich].
The wide applicability of zero-knowledge was demonstrated in Proofs that Yield Nothing But their Validity or All Languages in NP have Zero-Knowledge Proofs, coauthored by Goldreich, Micali and Wigderson [JACM, July 1991].
The dramatic effect of this result on the design of cryptographic protocols is demonstrated in another paper of the same authors; see webpage on How to Solve any Multi-Party Protocol Problem.
