Abstract: A data processing method performed by a first device includes: generating, in response to first service data satisfying a data uploading condition, a first bit array corresponding to the first service data; encrypting the first bit array through a data key to obtain a ciphertext bit array, the data key being generated by a second device in a data intersection application run in a trusted execution environment of the second device; and transmitting the ciphertext bit array to a blockchain node for forwarding to a second device, for the second device to decrypt, in the data intersection application through the data key, the ciphertext bit array to obtain the first bit array.

Abstract: In a blockchain transaction execution method, a first transaction of a first blockchain is received from a proxy program component. The first transaction is based on a second transaction of a second blockchain. A data structure of the first transaction is different from a data structure of the second transaction. The second transaction is extracted from the first transaction. A virtual machine is invoked to execute the second transaction of the second blockchain. An execution result of the second transaction is transmitted to the application via the proxy program component.

Abstract: In a blockchain data processing method, service updating data of each of a plurality of encrypted data is received. The service updating data of each of the plurality of encrypted data includes encrypted primary key information of the respective encrypted data. Each of the plurality of encrypted data includes service data encrypted by a respective service node of a plurality of service nodes. Service intersection data is generated based on a data intersection of the service updating data of the plurality of encrypted data. The service intersection data is transmitted to a service node of the plurality of service nodes. The service intersection data includes supplemental text data from another service node of the plurality of service nodes.

Abstract: A blockchain-based data processing method, apparatus, and computer-readable medium are provided. Block proposal information is received including a block and a digital signature transmitted by an out-block node. The digital signature is obtained by performing digital signature processing on block header information included in the block. The block header information includes a first Merkel root determined based on transaction data in the block body information. Digest calculation on the block header information is performed to obtain first digest information. De-signature processing is performed on the digital signature to obtain second digest information. A second Merkel root is determined based on the transaction data acquired from the block proposal information when the first digest information and the second digest information are matched. An operation on the block is performed based on a comparison result of the first Merkel root and the second Merkel root.

Abstract: Systems and methods for data formats which facilitate the encapsulation, transmission, reception, decomposition and processing of heterogeneous sets of data are disclosed. Data may be encoded in one of these data formats, and sent to a recipient, which decodes the data format and renders the data. These data formats may consist of the concatenation of a set of commands, each of these commands in turn composed of a tag, length and a payload. Furthermore, these data formats may provide a compact way to deliver information which allows the rendering of video, images, caption audio as well as user interaction functionality, while simultaneously reducing the computational complexity required of the recipient to decode the data format and render the varying types of data.

Abstract: A method and apparatus for dynamically adjusting timing parameters in a wireless data network is disclosed. A server system receives a set of timing statistics that may include a set of timing statistics measured by a wireless client and a set of timing statistics measured by a server device that services the wireless client. The timing statistics reflect the performance of the wireless network. Using the timing statistics and other timing related information such as the type of the wireless networks, the sever device determines a new set of timing parameters to be used by itself and the wireless client device or other client devices. Besides other functional values having impact on the performance of the wireless data network, the timing parameters include an ordered set of numbers that represents a back-off curve for message retransmission. The server device then transmits the new timing parameters respectively to one or more wireless client devices.

Abstract: The present invention has particular applications to the navigation of Internet web pages using two-way interactive communication devices, such as a mobile device, a mobile phone, a landline telephone, and an Internet capable remote controller. According to one aspect of the present invention, each of the two-way interactive communication devices is a node in a distributed network, thus the devices can access hypermedia or hierarchic layers of information stored in server devices on the network. When one or more pages of information are updated, rather than sending the entire updated information to users of the devices subscribing to the updated information through the network, the present invention sends a notification to a proxy server that forwards the notification to the users using a messaging system via a low cost narrowband channel. Upon receiving the notification, the users can fetch the updates, when needed, through a wideband channel.

Abstract: A credential caching proxy server that handles credential caching for a set of wireless client devices is disclosed. The credential caching proxy server handles most credential transactions for wireless client devices that wish to access resources within a protected realm where the protected realm requires credentials. In one embodiment, the credential caching proxy server intercepts and caches a wireless client's credentials when a credential is first sent from the wireless user agent to a protected server. The cached credential will then be used for all requests to resources within the same protected realm. Thus, after first sending a first credential for accessing the resource in a particular realm, the wireless user agent does not need to attach the credential for all the subsequent requests for any other resources belong to the same realm. In an alternate embodiment, the proxy server sends a special request to the wireless client device requesting a credential for a particular resource.

Abstract: The present invention is a method and system for establishing an authenticated and secure communication session for transactions between a server and a client in a wireless data network that generally comprises an airnet, a landline network and a link server therebetween. The client having limited computing resources is remotely located with respect to the server and communicates to the server through the wireless data network. To authenticate each other, the client and the server conduct two rounds of authentication, the client authentication and the server authentication, independently and respectively, each of the authentication processes is based on a shared secret encrypt key and challenge/response mechanism. To reach for a mutually accepted cipher in the subsequent transactions, the server looks up for a commonly used cipher and forwards the cipher along with a session key to the client.

Abstract: Techniques for ensuring secure access to local service of mobile devices of a wireless communication system are disclosed. The techniques control access to local services of mobile devices such that only authorized services are able to remotely alter the local services of the mobile devices. Before permitting access to local services of a mobile device, the identity of the network site seeking to have access is checked to determine whether the network site is authorized for such access. If the network site is authorized, then access is permitted and the network site is able to modify or alter the local services of the mobile device. On the other hand, when the network site is not authorized, then the network site is denied access to the local service so that the local services provided by the network site are not open to attack or corruption from unscrupulous network sites.

Abstract: A crypto-ignition process is needed to establish an encrypted communication protocol between two devices connected by an insecure communication link. The present invention introduces a method of creating an identical secret key to two communicating parties is conducted between a thin device and a server computer over an insecure data network. The thin device generally has limited computing power and working memory and the server computer may communicate with a plurality of such thin devices. To ensure the security of the secret key on both sides and reduce traffic in the network, only a pair of public values is exchanged between the thin device and the server computer over the data network. Each side generates its own secret key from a self-generated private value along with the received counterpart's public value according to a commonly used key agreement protocol, such as the Diffie-Hellman key agreement protocol.

Abstract: Improved techniques for providing reference numbers for purposes of fragmenting a message for transmission over a network (e.g., a wireless data network) that supports only a limited size message are disclosed. The reference numbers for the fragmented messages are shared by groups of destinations (e.g., subscribers or mobile devices). As a result, the number of reference numbers to be stored is small compared to the number of possible destinations, and the size of the reference numbers themselves is also kept small. The number of groupings and the size of the reference numbers can also be adjusted to fit system objectives.
