Publication number: 20230370451Abstract: 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.Type: ApplicationFiled: June 30, 2020Publication date: November 16, 2023Inventors: Mehdi Collinge, Omar Laazimani

Publication number: 20230327863Abstract: A method of providing a secure service at a computing node is described. The secure service is for a requesting party external to the computing node. The following steps take place at the computing node. A service request is received from the requesting party. This service request comprises a request to generate a credential. The credential is then generated, and service-related information is obtained. The credential and the service-related information are encrypted using an encryption process to form an encrypted message part. A service-identifying clear message part is also created, and a message is sent comprising the clear message part and the encrypted message part to the requesting party. Methods of using such a message to validate the credential, and of using such a message to confirm the integrity of service-related information held in the message, are also described, as is computing apparatus adapted to carry out one or more of these methods.Type: ApplicationFiled: July 22, 2021Publication date: October 12, 2023Applicant: MASTERCARD INTERNATIONAL INCORPORATEDInventors: Mehdi Collinge, Alan Johnson, Omar Laazimani

Publication number: 20220329409Abstract: 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.Type: ApplicationFiled: April 22, 2020Publication date: October 13, 2022Applicant: MASTERCARD INTERNATIONAL INCORPORATEDInventors: Mehdi Collinge, Omar Laazimani, Cristian Radu
