WebbWe propose the first cloud-based revocable identity-based proxy re-encryption (CR-IB-PRE) scheme that supports user revocation but also delegation of decryption rights. No matter a user is revoked or not, at the end of a given time period the cloud acting as a proxy will re-encrypt all ciphertexts of the user under the current time period to the next time period. A proxy re-encryption is generally used when one party, say Bob, wants to reveal the contents of messages sent to him and encrypted with his public key to a third party, Charlie, without revealing his private key to Charlie. Bob does not want the proxy to be able to read the contents of his messages. Bob could … Visa mer Proxy re-encryption (PRE) schemes are cryptosystems which allow third parties (proxies) to alter a ciphertext which has been encrypted for one party, so that it may be decrypted by another.

From the template key TK, the delegatee can derive his/her own puncture keys. The decryption of delegatee is input of the puncture key and his secret key. Webb1 mars 2024 · Proxy re-encryption ( \mathsf {PRE} ), envisoned by Blaze et al. [ 9] and formalized by Ateniese et al. [ 4, 5 ], is a cryptographic primitive that can be seen as an extension of public-key encryption. A central feature of \mathsf {PRE} is that senders can craft so-called re-encryption keys, which are usually created using only public ...
