In identity-based cryptography, a user's public key is easily derived from the user's identity and a corresponding private key is generated for the user by a trusted third party, known as a Key Generation Center (KGC). The direct derivation of public keys in identity-based cryptography can...

In this paper, we propose a mechanism to generate the user's private key in which we mitigate the trust on single PKG by replacing it with single semi-trusted key generation center (KGC), which authenticates the user and provide the partial private key and multiple cloud privacy centers (...
In certificateless signature(CLS) based on Al-Riyami frame, the secure condition is key generation center (KGC) which can not implement public key replacement attack. So CI_S can not resist this attack from KGC. A new sig- nature system called certificat
Key transfer protocols rely on a mutually trusted key generation center (KGC) to select session keys and then transports session keys to all communication entities secretly. In key agreement protocols, all communication entities collaboratively determine session keys. The most commonly used key agreement...
Key Generation Center can broadcast group key information to all group members at once under the secret shared with each user during registration and sends the cipher text to each group member separately. Key transfer protocols rely on a mutually trusted key generation center(KGC) to select ...
The www.jrret.com dynamic group based protocol based on Key Generation center (KGC) is used along with the short group signature scheme for giving access control to the authorized users. Many any small companies rely on the cloud IT services for their data sharing. Cloud always has the ...

Key transfer protocols rely on a mutually trusted key generation center (KGC) to select session keys and transport session keys to all communication entities secretly. Most often, KGC encrypts session keys under another secret key shared with each entity during registration. In this paper, we prop...
