Proxy re-encryption, abbreviated as PRE, is a cryptosystem which allows the proxy to re-encrypt a cirphertext without accessing the underlying message. The re-encryption protocol ...
Abstract. In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called proxy re-encryption, in which a proxy transforms – without seeing the corresponding plain...

In 1998, Blaze, Bleumer, and Strauss suggested a cryptographic primitive termed proxy re-signature in which a proxy transforms a signature computed under Alice's secret key in...
We propose a four-party password authenticated interdomain key exchange protocol which makes use of properties of identity-based cryptography and secret public keys. Being passwor...
