Abstract: Systems and methods for integration of components to facilitate executing transactions with different blockchain networks by using a standard API format. A standardized blockchain request identifying a blockchain network is received. The request is routed to a node synced with the blockchain network. A blockchain-specific call is constructed based on the standardized blockchain request. The blockchain network is interacted with using the blockchain-specific call. A response to the blockchain-specific call is returned in a standardized format.

Abstract: A peer-to-peer (P2P) distributed data management system (DDMS) may operate as an operating system on which P2P distributed applications are utilized to manage data on distributed ledgers, such as blockchains. The DDMS may enable fast development of secure and scalable enterprise P2P distributed applications that support permanent control of every piece of data on a distributed ledger, synchronization, normalization of the data, and encryption of the data. Security of the data in the distributed ledger means that even if someone hacks into the distributed ledger, access is only gained to one block of data (e.g., single email) and not all blocks of data (e.g., entire email account). The DDMS may be integrated into Internet-of-Things (IoT) devices. The DDMS further automatically supports sequential smart contracts on the distributed ledger.

Abstract: The disclosure is related to systems and methods for obfuscating keys. In one step the system divides a storage root key into at least two chunks. In another step the system processes each of the at least two chunks with at least one obfuscation algorithm to create at least two obfuscated chunks. In a further step the system stores each of the at least two obfuscated chunks in a storage file. In a further step, user keys are encrypted with the storage root key.

Abstract: Systems and methods for controlling data access through the interaction of a short-range transceiver, such as a contactless card, with a client device are presented. An exemplary system and method may include establishing a database storing identifiers and keys for users and service providers, receiving from a client device of the service provider, via a network, a service provider token and a request for a data access key, the request generated in response to a tap action between a contactless card associated with a user and the client device, verifying the service provider is authorized to receive access to personal user data encrypted and stored on the contactless card, generating a data access key based on a user key, and transmitting to the service provider client device, via the network, the data access key, such that the client device may decrypt the personal user data obtained from the contactless card.

Abstract: A system and method for signing or encrypting data is disclosed. The method comprises providing, from a first device, data signing information for storage in a first database, the data signing information having at least one key comprising a signing key Ks, wherein the signing key Ks is encrypted according to a wrapping key Kw before storage in the first database; receiving a data signing request comprising a representation of the data; retrieving, in a second device communicatively coupled to an hardware security module (HSM) storing the wrapping key Kw, the stored data signing information from a second database, wherein at least a portion of the second database including the stored signing information is pushed from the first database to the second database; decrypting, in the HSM, the encrypted signing key according to the wrapping key Kw stored in the HSM to recover the signing key Ks; and signing the representation of the data according to the recovered signing key.

Abstract: In one embodiment, a method for securely distributing secret keys for hardware devices is disclosed. A distributor server transmits to a provider server an order for hardware devices. Each hardware device has a unique identifier and at least one secret key for authentication. The provider server sends a database associated with the distributor, for each of the hardware devices, the unique identifier and an unencrypted version of the at least one secret key. In response to an order received by the distributor from a customer for a portion of the hardware devices, the distributor server provides the database the unique identifiers and an associated customer order identifier, and the distributor server provides a customer server the unique identifiers. In response to the customer logging into the database and providing the order information, the database provides the customer the unencrypted keys for the hardware devices to allow authentication.

Abstract: 本发明属于信息安全算法实现领域，具体涉及一种后量子密钥交换协议的实现方法及其应用，提出了一种新的公共多项式的生成方法，简化了密钥交换流程，减少了进行密钥交换所需时间，降低了服务器端到客户端的数据传输所需带宽；其次通过新的数据交换方案，具体通过握手信号使两端计算流程保持同步，保证了服务器端和客户端始终处于同一密钥交换过程。另外，通过分两次发送客户端信息，进一步降低了传输带宽。本发明通过设计客户端和服务器端的状态同步机制，保证了每次密钥交换开始时两端的Trivium模块处于相同的状态，避免了重新初始化该模块，提高了整个系统的运行效率。
