Abstract

A method for authenticating a data agreement between first and second network entities can include the first network entity committing to the agreed data value, and transmitting the committed data value and a first random value to the second network entity. The first network entity can receive a second random value, and can then open the committed data value such that the second network entity can check the committed data value. If successful, the second network entity can calculate a third check string, and the first network entity can similarly calculate a fourth check string, based upon the data value and the first and second random values. The first network entity can calculate the fourth check string without the second network entity committing to the data value. The method can then include comparing the check strings such that the agreed data can be considered authenticated based upon the comparison.

Description

technical field [0001] The present invention relates generally to systems and methods for authenticating data negotiation between network entities, and more particularly to a system for authenticating key agreement between network entities during connection establishment between the network entities and methods. Background technique [0002] In this specification, the concept of a short-range wireless data transfer connection mainly relates to a connection in which two or more devices or entities arranged relatively close to each other can communicate with each other wirelessly. In this communication, for example, wireless communication, infrared communication, inductive communication, etc. can be applied. For example, Bluetooth (Bluetooth) using a low-power wireless transmitter and wireless receiver has been developed for short-range wireless communication. TM )technology. Such devices can communicate with each other and thereby form an ad-hoc network. For example, peri...
