    Abstract: Instead of requiring key exchange between a trusted biometric application in a TEE and an external application outside of the TEE that provides access to a secured function, the trusted application is preconfigured with security data such as (in a first implementation) authentication credentials (e.g. a PIN) or (in a second implementation) a cryptographic key. This security data is then used to authenticate a biometric validation obtained by the trusted application to the external application.

    Abstract translation: 不需要在TEE中的可信生物特征应用与TEE之外的提供对安全功能的访问的外部应用之间的密钥交换，所述可信应用是预先配置有安全数据，例如（在第一实现中）认证证书（例如 PIN）或（在第二实现中）密码密钥。 然后将该安全数据用于认证由可信应用程序获取到的外部应用程序的生物特征验证。

    Abstract: A method of maintaining a secure relationship between a client device and a server is described. The client device receives a first challenge from the server and determines and provides a first response to the first challenge. A cookie is established associated with the secure relationship. This cookie is shared between the client and the server. To establish the secure relationship in a later interaction, the client provides the cookie to the server. The server then provides both the first challenge and a second challenge, to which the client determines a first response and a second response. The client then provides a composite response from which the first response and the second response are derivable by the server, allowing the server to be assured that the secure relationship exists. Each challenge uses a challenge function adapted to provide a fingerprint of the client device. Methods at both client and server, and suitably configured client and server, are also described.

    Abstract: A method is described of managing service events in a distributed computing system. The distributed computing system comprises a plurality of computing nodes able to perform a service using a service process. The method takes place at one of the computing nodes. A service event is received or created. This service event is identified by a combination of a node identifier, a time element, and a local counter value. The local counter value represents a number of service events performed by a service process for a user since a last reset. The identified service event is then stored in a service process database according to node identifier and local counter values. The service process database is used to manage service events in the distributed system. Service events are removed from the service process database when no longer valid using the time element.

    Abstract: A method of providing a secure service at a computing node for a requesting party external to the computing node is described. The following steps are taken at the computing node. A service request comprising a request to generate a credential is received from a requesting party. The computing node generates the credential and obtains service-related information. A clear message part is created comprising service-identifying information. A checksum is then created from at least a part of the service-identifying information and from at least a part of the credential and the service-related information. The credential, the service-related information and the checksum are then encrypted to form an encrypted message part. A message comprising the clear message part and the encrypted message part is then sent to the requesting party. Methods for providing secure services to validate the credential and to obtain the service-related information are also described, as is computing apparatus adapted to perform all these methods.

    Abstract: Methods, apparatus and systems for operating a payment-enabled mobile device to facilitate a payment transaction with a merchant server. In an embodiment, a mobile device processor of the payment-enabled mobile device receives a payment transaction request from a user, transmits a payment transaction initiation message directly to a merchant server of the merchant, and receives a request message from the merchant server that includes one of a request to provide an Authorization Request Cryptogram (ARQC) or a request to provide user consent information. The user consent information may include cardholder verification results or a request to provide an ARQC. Based on the received request message, the mobile device processor selects a particular mobile payment cardlet to use from a plurality of mobile payment cardlets running in a secure element, generates remote payment data using the particular mobile payment cardlet, and transmits the remote payment data to the merchant server to process the payment transaction.

    Abstract: A computing node in a distributed information security system, wherein the computing node is adapted to communicate with a subset of clients of the distributed information security system, wherein the computing node provides at least one cryptographic service for the clients of the subset, wherein the computing node is provisioned with a plurality of keys for use by said at least one cryptographic service, wherein the computing node is adapted to associate a key from the plurality of keys to a service request for a client according to a deterministic process based on one or more data associated with the client. A distributed information security system comprising a plurality of such nodes is also described, together with a method of providing a cryptographic service at such a computing node.

    Abstract: A method for a computing node to provide a cryptographic key in response to a service request, the method comprising: establishing a key list, wherein the key list comprises key identifiers for a plurality of keys; receiving a service request and identifying that a key is required in response to the service request; and using a deterministic process from data associated with the service request to allocate one of the key identifiers and hence the key associated with said one of the key identifiers to the service request. A suitably configured computing node is also described.
