"It was a secure time in history between great upheavals" -- World War II and the student riots of the 60's in Paris.
Firstly, we derive the requirements for a secure time synchronization service for WSNs.
We first derive the requirements for a secure time synchronization service for WSNs.
Section 2 derives the requirements for a secure time synchronization service and evaluates existing secure time synchronization proposals.
A secure time synchronization service for WSNs must comply and trade off the following requirements: low cost, accurate, precise, secure, and periodically-scheduled.
Using Callisto, a victim can create a secure, time-stamped record of her assault, a so-called "information escrow".
It's not like trying to blend in and have a nice quiet secure time, it's far more desperate".
Fourthly, we propose a novel system for secure time synchronization in a WSN.
This paper addresses the challenges of sensor network engineering by proposing an efficient and secure time synchronization protocol named Tempest.
This service creates a secure electronic time and date stamp for e-mail messages, showing proof that important financial, legal, medical, government and educational documents are delivered.
Most applications will probably end up using Internet Protocol Security (IPsec) or transport layer security (TLS /secure sockets layer (SSL) for ensuring secure signaling and will use Secure Real-time Transport protocol (SRTP) for a secure Real-time Transport Protocol (RTP) stream in voice communication.
