    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 posesses 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 to affix a partial signature among a plurality of authorizing agents.

    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: 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.
