Filed:

Jun 22, 2001

Appl. No.:

09/887599

Inventors:

Peter Yianilos - Princeton NJ, US
Joseph Kilian - Princeton Junction NJ, US

International Classification:

G06F011/30
H04L009/00

US Classification:

713/153000, 713/187000, 713/189000, 713/201000

Abstract:

A computer platform is described that provides control features to allow for the protection of intellectual property rights and prevent malfunctioning of the platform. The platform uses 1) a secure operating system including a secure memory management system, 2) public key encryption, 3) data authentication through digital signatures and 4) application/data approval through a flexible access policy through the use of object handlers and an application program approval process. Through these four control features, the platform provides the ability to control access to data and minimize the effects of computer malfunctions.

Appl. No.:

8/376568

Inventors:

Joseph John Kilian - Princeton Junction NJ
Kazue Sako - Kawasaki, JP

Assignee:

NEC Research Institute, Inc. - Princeton NJ

International Classification:

H04L 930
G06F 1760

US Classification:

380 30

Abstract:

A number-theoretic based algorithm provides for secure anonymous message transfer and electronic voting. A voter or sender may cast an encrypted vote or message that is processed through n centers in a manner which prevents fraud and authenticates the votes. Any interested party can verify that each vote has been properly counted. The invention can be realized by current-generation personal computers with access to an electronic bulletin board.

International Classification:

H04L 936
G06F 1760

US Classification:

705 12

Abstract:

A number-theoretic based algorithm provides for secure receipt-free voting. A vote generating center generates a choice of votes for each voter or vote chooser. The votes are encrypted, shuffled, and conveyed to a vote chooser along with information regarding how the votes were shuffled without being intercepted en route. The information is preferably sent along untappable secure channels. The method can incorporate validation of generation and shuffling of the votes using chameleon commitment and interactive proofs. The invention can be realized by current-generation personal computers with untappable channels and access to an electronic bulletin board.

US Classification:

380 30

Abstract:

A number-theoretic based algorithm provides for secure electronic voting. A voter may cast a votes among n centers in a manner which prevents fraud and authenticates the votes. Preprocessing allows for nearly all of the communication and computation to be performed before any voting takes place. Each center can verify that each vote has been properly counted. The algorithm is based on families of homomorphic encryptions which have a partial compatibility property. The invention can be realized by current-generation PCs with access to an electronic bulletin board.
