Tseng et al. have introduced in 2003 an authenticated encryption scheme by using self-certified public keys. Based on this scheme several authors have proposed new signature schem...
The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Several ...
Unforgeability and blindness are two important properties of blind signature. The latter means that after interacting with various users, the signer is unable to link a valid messa...
In [7] we have proposed a model for the robust and private evaluation of a function within a group of cooperating mobile agents, called an agent Alliance. The model has been given...
We investigate unconditional security for message authentication protocols that are designed using two-channel cryptography. We look at both noninteractive message authentication ...
