摘要： A system and method for conducting verifiably correct auctions that preserves the secrecy of the bids while providing for verifiable correctness and trustworthiness of the auction is disclosed. Some of the elements of the method and apparatus are that the auction operator accepts all bids submitted and follows the published rules of the auction. In one embodiment, the bids are maintained secret from the auctioneer and all bidders until the auction closes and no bidder is able to change or repudiate her bid. In another embodiment, the auction operator computes the auction results and publishes proofs of the results' correctness. In yet another embodiment, any party can check these proofs of correctness via publicly verifiable to computations on encrypted bids.
摘要翻译：公开了一种用于进行可验证的正确拍卖的系统和方法，其保证了出价的保密性，同时提供了可验证的正确性和可信度的拍卖。方法和设备的一些要素是拍卖经营者接受提交的所有投标书，并遵循已发布的拍卖规则。在一个实施例中，出价由拍卖人和所有投标者保持秘密，直到拍卖结束，没有投标人能够改变或拒绝其出价。在另一个实施例中，拍卖运营商计算拍卖结果并公布结果正确性的证明。在另一个实施例中，任何一方都可以通过可公开验证的加密出价计算来检查这些正确性证明。

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+.delta., 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. 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.

摘要： According to one aspect, provided is a construction and specification for an implementation of a new cryptographic primitive, “Time-Lapse Cryptography”, with which a sender can encrypt a message so that it is guaranteed to be revealed at an exact moment in the future, even if this revelation turns out to be undesirable to the sender. 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,

摘要： A system for protecting software against piracy while protecting a user's privacy enables enhancements to the protection software in a user device and extended protections against piracy. The protection system allows the user device to postpone validation of purchased tags stored in a tag table for installed software and to re-establish ownership of a tag table to recover from invalidation of a tag table identifier value resulting from revelation of a tag table identifier value. Continued use of the tag table is provided by the use of credits associated with a tag table. A protection center is protected against denial of service attacks by making calls to the protection center cost time or money to the attackers.

摘要： Presented are methods and systems for highly efficient proofs of correctness of computations that preserve secrecy of the input values and calculations. One embodiment includes a method for verifiably determining at least one output for a secrecy preserving computations where the method includes acts of calculating an output from submitted inputs according to an announced calculation, translating a value in the calculation into two components that are a randomized representation of that value, publishing commitments to the at least two components, revealing a portion of the randomized representation in response to a verification request, and enabling verification of the calculation of the output using the revealed portion of the randomized representation. According to one aspect of the secrecy preserving verification the numbers involved in the secrecy preserving calculation are represented by a randomly constructed representing pair. In another aspect, revealing one member of the pair allows for verification without compromising secrecy. In one embodiment, arrangement of the translation process ensures that in the verification only truly independently random numbers, or operations on them, are revealed and checked.

摘要： System, methods and apparatus are applicable to enable owners and vendors of software to protect their intellectual property and other rights in that software. The system also enables vendors or distributors of software to charge per-use for an instance of software. The system produces a unique, unforgeable, tag for every vendor supplied instance (copy) of specific software. Each user device is equipped with a supervising program that ensures, by use of the tag and other information, that no software instance will be used on the device in a manner infringing on the vendor, distributor, or software owner's rights. When installing or using a vendor-supplied software instance, the supervising program verifies the associated tag and stores the tag. When installing or using untagged software, the supervising program fingerprints selected portions of the software and stores the fingerprints. Software is used on a user's device through the supervising program which ensures proper use of the software. A vendor can submit a copy of infringing software to a guardian center which fingerprints appropriate portions of the infringing software. A user device's (104) supervising program periodically calls up, or can be called up, by the guardian center. During call-up, the supervising program can securely sends to the guardian center information about the use of the software instances associated with tags and fingerprints. The guardian center detects unauthorized use of software by comparison of current call-up data with records of past call-ups involving the same tags, and/or by comparing call-up supplied fingerprints with fingerprints of infringing software stored by the guardian center. The guardian center completes the call-up by enabling continued use of properly used software instances and generating appropriate punitive actions upon detection of improperly used software instances on the calling user's device. The data supplied by a supervising program during call-up is also employed by the guardian center to prepare data on usage by a user's device of vendor or distributor supplied software instances, for pay-per-use or pay-per-view billing.
