摘要： A robust computational secret sharing scheme that provides for the efficient distribution and subsequent recovery of a private data is disclosed. A cryptographic key may be randomly generated and then shared using a secret sharing algorithm to generate a collection of key shares. The private data may be encrypted using the key, resulting in a ciphertext. The ciphertext may then be broken into ciphertext fragments using an Information Dispersal Algorithm. Each key share and a corresponding ciphertext fragment are provided as input to a committal method of a probabilistic commitment scheme, resulting in a committal value and a decommittal value. The share for the robust computational secret sharing scheme may be obtained by combining the key share, the ciphertext fragment, the decommittal value, and the vector of committal values.

摘要： A system for securing information, includes a processor and storage device. The storage device stores information encrypted with one of a first private rolling key and a first public rolling key of an a first asymmetric rolling crypto-key, along with the one first rolling key. The processor has the logic to direct transmission, via a network, of proof of knowledge of the stored one first rolling key to authenticate a user, and of a request for the other of the first private rolling key and the first public rolling key. The processor receives the other first rolling key via the network, responsive to the directed transmission. The processor then decrypts the stored encrypted information with the received other first rolling key, and generates a second asymmetric rolling crypto-key having a second private rolling key and a second public rolling key. The processor encrypts the information with one of the second private rolling key and the second public rolling key. The processor also directs transmission of the other of the second private rolling key and the second public rolling key via the network. The storage device stores the information encrypted with the one second rolling key and the one second rolling key itself.

摘要： A first network station encrypts a first message with a first key portion from a first split of a private or public key of a user's asymmetric crypto-key and transmits it during a network session. The second network station decrypts the transmitted encrypted first message with a second key portion from the first split of the one key of the asymmetric crypto-key to initially authenticate the user for access, during the session, to store information. The first network station also encrypts a second message with another first key portion from a second split of that one key, and subsequently transmits it during the same network session. The second network station decrypts the subsequently transmitted encrypted second message with another second key portion from the second split of that same one key to subsequently authenticate the user for access, during the same session, to other stored_information.

摘要： A processor generates an asymmetric crypto-key, such as an RSA crypto-key, which is associated with the user and includes a private key and a public key. It computes a first key portion based on a stored random number generation function, which has one or more constants such as a salt and/or iteration count, and a first value of a constant, and a second key portion based on the computed first key portion and one of the private key and the public key. It additionally computes another first key portion based on the stored random number generation function and a second value of that constant, and another second key portion based on the computed other first key portion and the one key. The computed first and second key portions and the computed other first and second key portions form first and second splits of the one key of the asymmetric crypto-key.

摘要： Techniques for user authentication based upon an asymmetric key pair having a public key and a split private key are provided. A first portion of the split private key is generated based upon multiple factors under control of the user. The factors include a password. A challenge is cryptographically combined with a first one of the multiple factors, but not the user password, to form a first message. The first message is transformed with the generated first portion to form a second message, which is then sent to an authentication entity. The sent second message is transformed to authenticate the user by proving direct verification of user control of the first factor.
