Secure client-side communication between multiple domains

摘要

Methods and systems for secure client-side communication between multiple domains is provided. Such methods and systems can provide for decreased communication latency particularly effective for dynamic multi-domain and/or multi-tenant environments while allowing for granular security or specific security of messages and operations with regard to users, user sessions, groups, organizations, permissions sets, applications, or any other logical delineation. Such methods and systems may involve a variety of security components, for example, at least one set of instructions including a plurality of defined instruction to be utilized by users of the set of instructions to communicate, and cryptographic construct data in order to verify the data integrity and the authenticity of messages sent and received using the secure client-side communication between multiple domains.

1. A method comprising:
providing, from a client, authentication information of a user for a first domain and a second domain to a server; receiving, by the client, a set of instructions and cryptographic construct data from the server, the set of instructions including information mapping one or more operations to at least one instruction ID; identifying, by the client, a first instruction ID from the set of instructions corresponding to a first set of one or more operations that are permitted to be used in client-side communication between the first domain and the second domain; generating, by the client, using one or more processors in one or more computer systems, a first message using the cryptographic construct data and including the first instruction ID; and sending the first message to a recipient.
