	abstract = {We present a new class of distributed key generation and recovery algorithms suitable for group communication systems where the group membership is either static or slowly time-varying, and must be tightly controlled. The proposed key generation approach allows entities which may have only partial trust in each other to jointly generate a shared key without the aid of an external third party. The group collectively generates and maintains a dynamic group parameter, and the shared key is generated using a pseudo random function using this parameter as a seed. The validity of key generation can be checked using veriable secret sharing techniques. The key retrieval method does not require the keys to be stored in an external retrieval center. We note that many Internet-based applications may have these requirements. Fulllment of these requirements is realized through the use of fractional keys-a distributed technique recently developed to enhance the security of distributed systems in a non-cryptographic manner.},

	title = {A Scalable Extension of Group Key Management Protocol},

	abstract = {This paper presents a robust, scalable extension to the recently proposed multicast Group Key Management Protocol (GKMP) ([1], [2]), in terms of security administration. The GKMP has two major security related problems: (a) lack of any mechanism to remove a compromised group administrator, and (b) lack of scalability. We are able to remove a compromised single panel member from generating the group keys by setting the panel members with shared authority to generate the group keys. We then introduce the sub-controllers who have all the functionalities of the group control panel except the authority to generate the group keys. The sub-control panel helps scalability of the network in terms of the security operations. The sub-controllers are chosen using a threshold-based clustering algorithm.},
