摘要： A method of unwrapping wrapped digital data that is unusable while wrapped, includes obtaining an acceptance phrase from a user; deriving a cryptographic key from the acceptance phrase; and unwrapping the package of digital data using the derived cryptographic key. The acceptance phrase is a phrase entered by a user in response to information provided to the user. The information and the acceptance phrase can be in any appropriate language. The digital data includes, alone or in combination, any of: software, a cryptographic key, an identifying certificate, an authorizing certificate, a data element or field of an identifying or authorizing certificate, a data file representing an images, data representing text, numbers, audio, and video.

摘要： A multi-step digital signature system and method is provided having a distributed root certifying authority 20. Messages received at the root certifying authority 20 are distributed to root certifying authority members 22-30 who attach partial signatures to the message using root key fragments. In the system and method provided, the system adapts to system events such as the addition or removal of key fragment holders, the need to modify key fragments, etc., by changing key fragments.

摘要： A multi-step signing system and method uses multiple signing devices to affix a single signature which can be verified using a single public verification key. Each signing device possesses a share of the signature key and affixes a partial signature in response to authorization from a plurality of authorizing agents. In a serial embodiment, after a first partial signature has been affixed, a second signing device exponentiates the first partial signature. In a parallel embodiment, each signing device affixes a partial signature, and the plurality of partial signatures are multiplied together to form the final signature. Security of the system is enhanced by distributing capability to affix signatures among a plurality of signing devices and by distributing authority us affix a partial signature among a plurality of authorizing agents.
摘要翻译： 多步签名系统和方法使用多个签名设备来附加可以使用单个公共验证密钥进行验证的单个签名。 每个签名装置具有签名密钥的共享，并且响应于来自多个授权代理的授权而附加部分签名。 在一个串行实施例中，在第一部分签名被贴上之后，第二签名装置指数第一部分签名。 在一个平行实施例中，每个签名装置贴上部分签名，并将多个部分签名相乘在一起形成最终签名。 通过在多个签名装置之间分配能力来贴附签名来增强系统的安全性，并且通过分配授权我们在多个授权代理之间附加部分签名。

摘要： The present invention relates to synthetic funds for purchase by investors. A structured note is structured to provide customized equity returns/exposure. Terms of each structured note may be specified by the purchaser and the structured notes may be unsecured liabilities of the obligor, e.g., there are no underlying assets upon which the structure note is based. Thus, there will be no limits on the use of structured note proceeds and management of assets and liabilities will be left entirely to the obligor's discretion. Structured note payment obligations may be related to the performance of an objective valuation, but structured note holders will depend on the good credit of the obligor for payment.
