Symmetric revocable encryption
WebThe invention discloses a searchable public key encryption method. Firstly, a receiver set is defined, a data owner selects keywords, a file is encrypted by the adoption of an encryption algorithm, the keywords are encrypted by the adoption of a searchable public key encryption scheme, the data owner employs information of the to-be-assigned receiver to generate … WebTo deal with dynamically alternate user’s credentials in identity-based encryption (IBE), providing the efficient key revocation method is a very critical issue. Lately, Ma and Lin proposed a generic method out designing a revocable IBE (RIBE) scheme that uses the complete subtree (CS) approach by combining IBE and ranked IBE (HIBE) schemes. In this …

WebFeb 3, 2024 · Symmetric key encryption is a method of securing data through ciphers. This works by taking plain text and scrambling it while in transit, then returning it to plain text so the proper recipient can access it. In this system, both the encryption and description use the same key or cipher. Block: In this process, chunks of data decrypt and stay ... WebTo this end, we first introduce a new cryptographic primitive, named Symmetric Revocable Encryption (SRE), and propose a modular construction from some succinct cryptographic primitives. Then we present our DSSE scheme based on the proposed SRE, and instantiate it with lightweight symmetric primitives. At last, we implement our scheme and
WebNov 23, 2024 · Once the symmetric encryption algorithm and key are applied to that data, it becomes unreadable ciphertext. The way to decrypt that message to decipher its meaning is to use a decryption key. In the case of symmetric encryption, the decryption key is identical to the key that was used to encrypt the data. Basically, you use the same key twice. WebJan 18, 2024 · Symmetric encryption is a fast and secure type of encryption that uses a single key for encryption and decryption.
