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 + d, 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, and in one embodiment, only components generated by parties verified proper are used. A time is associated with the generated public key, which may set a future point at which a secret key will be created, and/or published. When a predetermined time is reached, and in some embodiments, slightly before, construction of the secret key begins. In one alternative, it may be necessary to reconstruct various components used to generate the secret key. In another, the secret key is generated from at least a portion of a plurality of the cryptographic key components.

摘要： Methods and apparatus to enable owners and vendors of software to protect intellectual property and to charge per-use. The system produces a unique tag for every instance of software. Each user device runs a supervising program that ensures, by use of the tag, that no software instance will be used infringing on the software owner's rights. When installing or using a 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. A user device's supervising program periodically calls up, or is called up by a guardian center. The guardian center detects unauthorized use of software by comparison of current call-up data with records of past call-ups. The guardian center completes the call-up by enabling or disabling continued use of the monitored software instances.
摘要翻译：使软件所有者和供应商保护知识产权并对每次使用收费的方法和设备。该系统为每个软件实例生成一个唯一的标签。每个用户设备运行一个监督程序，通过使用标签，确保不会使用软件实例来侵犯软件所有者的权利。在安装或使用软件实例时，监督程序将验证相关标签并存储标签。当安装或使用未标记的软件时，监督程序指纹软件的所选部分并存储指纹。用户设备的监督程序定期召唤或由监护人中心呼叫。监护人中心通过比较目前的呼叫数据和过去的呼叫记录来检测未经授权的使用软件。监护人中心通过启用或禁用继续使用受监视的软件实例来完成呼叫。

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 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经加密出价的可公认验证的计算来检查这些正确性证明。
