Method and apparatus to obtain negotiated service advertisement
TLDR
In this article, the authors propose a service discovery mechanism that allows a client to request a capability credential from a service and the service may then respond with the capability credential that may convey to the client the rights to use the requested capabilities.Abstract:
A service discovery mechanism may allow clients in a distributed computing environment to search for services. The service discovery mechanism may allow a client to request a capability credential from a service. The distributed computing environment may include a mechanism for a client to negotiate service access rights and to then obtain a capability credential that may be used to obtain the service's access interface to the set or subset of the service's capabilities that were requested or negotiated by the client. In one embodiment, the client may present to the service a set of desired capabilities. The service may then respond with a capability credential that may convey to the client the rights to use the requested capabilities. A complete service advertisement may be needed to create a message endpoint for accessing the service. In an embodiment, the capability credential may be used by a client to obtain a complete advertisement for only the requested or negotiated capabilities. The capability credential may provide an additional level of security for the service provider. The capability credential that may be used to receive the complete advertisement may also be used to construct a message gate to communicate with the service where the gate embeds the capability credential in each message to the service.read more

Learning Device Interaction Rules
TL;DR: In this article, devices and methods are disclosed for establishing interaction among electronic devices of an environment. But the devices are not discussed in detail, except for the one or more devices that observe at each device a change of state activity among the plurality of devices.

Registration, verification and notification system
TL;DR: In this paper, a registrant provides at least one registrant electronic contact, such as a telephone number, during a registration process and the registrant's information may be compared to a database of such information.

System and method for validating program execution at run-time
TL;DR: In this article, a pipelined processor comprising a cache memory system, fetching instructions for execution from a portion of said cache memory systems, an instruction commencing processing before a digital signature of the cache line that contained the instruction is verified against a reference signature of cache line, the verification being done at the point of decoding, dispatching, or committing execution of the instruction, the reference signature being stored in an encrypted form in the processor's memory, and the key for decrypting the said reference signature was stored in a secure storage location.

The Byzantine Generals Problem
TL;DR: The Albanian Generals Problem as mentioned in this paper is a generalization of Dijkstra's dining philosophers problem, where two generals have to come to a common agreement on whether to attack or retreat, but can communicate only by sending messengers who might never arrive.

Generative communication in Linda
TL;DR: This work is particularly concerned with implementation of the dynamic global name space that the generative communication model requires, and its implications for systems programming in distributed settings generally and on integrated network computers in particular.

Self-stabilizing systems in spite of distributed control
TL;DR: In this paper, the synchronization task between loosely coupled cyclic sequential processes is viewed as keeping the relation "the system is in a legitimate state" invariant, and each individual process step that could possibly cause violation of that relation is preceded by a test deciding whether the process in question is allowed to proceed or has to be delayed.

Implementing remote procedure calls
TL;DR: The overall structure of the RPC mechanism, the facilities for binding RPC clients, the transport level communication protocol, and some performance measurements are described, including some optimizations used to achieve high performance and to minimize the load on server machines that have many clients.

TL;DR: Observations of a prototype implementation are presented, changes in the areas of cache validation, server process structure, name translation, and low-level storage representation are motivated, and Andrews ability to scale gracefully is quantitatively demonstrated.
