In one embodiment, a Time-Lapse Cryptography Service is provided (“the Service”) based on a network of parties. Senders encrypt their messages with this public key whose secret key is not known to anyone—not even a trusted third party—until a predefined and specific future time T+δ, at which point the secret key is constructed and published. In one example, the secret key can only be known after it is constructed. At or after that time, anyone can decrypt the cipher text using this secret key. Other embodiments describe other applications of such a service, for example, one embodiment is used in sealed bid auctions, others in insider stock sales, clinical trials, and electronic voting, among a variety of possible implementations. In one embodiment, a method for cryptographic encoding is provided, including generation of cryptographic key components by a plurality of parties, where participation of the parties is verified. A public key is constructed from a plurality of key components, | 2010-07-22 |
20100185864 | Multi-Dimensional Credentialing Using Veiled Certificates - In accordance with certain embodiments of the present disclosure, a method for creating a veiled certificate is provided. The method comprises requesting a certificate from a regulator by sending a message with a digital signature of the message signed by the owner. The message comprises an owner's veiled certificate token, the veiled certificate token comprising an encrypted version of the owner's identification data and the owner's identification public key for the certificate. The message further comprises the identification public key, the whole message being encrypted using the regulator's external public key. The certificate request is validated by verifying the sender's identity through validation of the digital signature using the owner's external public key and verifying the veiled certificate token using the individual' external public key. A veiled certificate is created by combining the veiled certificate token, identification public key and digitally signing the veiled certificate with the regulator's private key, wherein the owner's identification information is inaccessible from the veiled certificate, except to the certificate owner. | 2010-07-22 |
