摘要： AKE with derived ephemeral keys is described. In one aspect, a first party computes a derived ephemeral public-key based on a derived ephemeral secret key and a mathematical group. The derived ephemeral secret key is based on an ephemeral secret key and a long-term secret key. The first party generates a session key for secure exchange of information with a second party. The session key is generated using the derived ephemeral secret key and a second party derived ephemeral public-key key to demonstrate to the second party that the first party possesses the long-term secret key.

摘要： Key confirmed (KC) authenticated key exchange (AKE) with derived ephemeral keys protocol using a mathematical group is described. In one aspect, a first party, using the mathematical group, determines whether a second party has received information to compute an agreed session key value for exchanging information securely with the first party. At least a subset of the received information is computed using derived ephemeral keys of the first and second parties. The first party generates the agreed session key value only when the second party has demonstrated receipt of the information.
摘要翻译：描述了使用数学群组进行密钥确认（KC）认证密钥交换（AKE）与派生短暂密钥协议。在一个方面，第一方使用数学组来确定第二方是否已经接收到用于计算商定的会话密钥值的信息，用于与第一方安全地交换信息。使用第一方和第二方的派生临时密钥来计算接收到的信息的至少一个子集。第一方仅在第二方已经显示收到信息时才生成约定的会话密钥值。

摘要： Systems and methods are described for trapdoor pairing. In one implementation, a trapdoor pairing is a cryptographic primitive generated by determining a bilinear pairing between an elliptic curve group and another group and selecting a parameter of the bilinear pairing, such as a group order or an isogeny between curves, to be a key for generating and evaluating the bilinear pairing. Trapdoor pairing allows construction of a group in which the Decisional Diffie-Hellman (DDH) problem is computationally infeasible given only the description of the group, but is easy given the secret key. Exemplary trapdoor pairing constructions have general applicability to cryptography and also lend themselves more specifically to certain special practical implementations, such as public key cryptography and certificate authority infrastructures.

摘要： Extended authenticated key exchange is described. In one aspect, an identity (IDA) of an initiator and an identity (IDB) of a responder are determined. A first party (i.e., the initiator or the responder) computes a session key based at least on IDA and IDB. A second party (i.e., the initiator or the responder) that is not the first party, uses at least IDA and IDB to compute a corresponding session key. The initiator's session key and the responder's corresponding session key, if equal, provide for secure exchange of data between the initiator and the responder.

摘要： Extended authenticated key exchange with key confirmation is described. In one aspect, and before computing session keys to exchange information securely between an initiator and a responder, each party of the initiator and the responder, confirms whether the other party has received corresponding information to generate a valid session key. If either party determines that the other respective party has not received the corresponding information, the party terminates the extended authenticated key exchange with key confirmation protocol. Otherwise, when a party determines that the other party has received the corresponding information, the party generates a respective session key. In this manner, when both parties confirm that the other party has received the appropriate information for session key generation, both parties are assured that information can be exchanged between the parties securely using the session keys.
摘要翻译：描述了密钥确认的扩展认证密钥交换。在一个方面中，并且在计算会话密钥之前，安全地在发起者和应答者之间交换信息，发起者和应答者的每一方确认对方是否已经接收到相应的信息以生成有效的会话密钥。如果任一方确定其他各方尚未收到相应的信息，则该方以密钥确认协议终止扩展认证密钥交换。否则，当方确定对方已经接收到相应的信息时，该方生成相应的会话密钥。以这种方式，当双方确认对方已经接收到用于会话密钥生成的适当信息时，确保双方可以使用会话密钥安全地在各方之间交换信息。

摘要： A backup system that utilizes contextual and semantic concepts is described. The backup system provides for the ability to create a version changes log for listing and tracking all the changes in the different versions of the file. The version changes log creates a contextual description around the changes, deletions and additions. The semantic concept log is created from the version changes log to create a log of all of the semantic concepts associated with each change. A visualization builder then creates visualizations that can be used by the user to search for changes, deletions and additions whether in a text file or an image file.

摘要： Pseudorandom numbers may be generated from input seeds using expander graphs. Expander graphs are a collection of vertices that are interconnected via edges. Generally, a walk around an expander graph is determined responsive to an input seed, and a pseudorandom number is produced based on vertex names. Specifically, a next edge, which is one of multiple edges emanating from a current vertex, is selected responsive to an extracted seed chunk. The next edge is traversed to reach a next vertex. The name of the next vertex is ascertained and used as a portion of the pseudorandom number being produced by the walk around the expander graph.
