What is the proxy re-encryption method?

I am the co-founder of BeSafe - Encrypted Cloud Collaboration which is the next generation data encryption and sharing platform heavily employing Proxy Re-Encryption algorithms. So let me tell you what proxy re-encryption is and where you can meet its true power. read more

A weaker re-encryption scheme is one in which the proxy possesses both parties' keys simultaneously. One key decrypts a plaintext, while the other encrypts it. Since the goal of many proxy re-encryption schemes is to avoid revealing either of the keys or the underlying plaintext to the proxy, this method is not ideal. read more

Proxy Re-encryption: The goal of proxy re-encryption is to securely enable the reencryption of ciphertexts from one secret key to another, without relying on trusted parties. For example if Alice receives emails from many clients encrypted under her public key. read more
