A Scalable Key Agreement Scheme For Large Scale NetworksKey Agreement Scheme • November 14th, 2005
Key agreement is a central problem to build up secure infrastructures for networks, because all secure primitives including encryption and authentication are based on keys. A general scenario is the two-party key agreement between any two nodes in a network. Though public key schemes outperform symmetric key schemes in terms of flexible man- ageability, their efficacy relies on the authenticity of public keys. Hence, public key schemes are usually applicable in the networks including fixed authorities who are in charge of the authentication of public keys. However, there are many sce- narios, e.g., dynamic conferences or ad hoc networks, where such authorities are not available. In addition, public key schemes require more computation resources than symmetric key schemes. Hence, in large scale networks, symmetric key schemes are pretty suitable because of their efficiency.
