Proxy re-encryption (PRE) is a cryptographic primitive in which a proxy can transform Alice’s ciphertexts
into ones decryptable by Bob. Key-private PRE specifies an additional level of security, requ...
Proxy re-encryption (PRE) was introduced by Blaze, Bleumer and Strauss [Eurocrypt '98]. Basically, PRE allows a semi-trusted proxy to transform a ciphertext encrypted under one key into an encryption ...
