WebFeb 29, 2024 · Block Diagram of Digital Signature The digital signature scheme depends on public-key cryptography in this algorithm. Explanation of the block diagram Firstly, each person adopting this scheme has a public-private key pair in cryptography. The key pairs used for encryption or decryption and signing or verifying are different for every signature. WebIn this paper, a novel scheme for secure and real time image transmission is introduced. The scheme uses a block-based elliptic curve (BBEC) public key encryption as a first stage of encryption so it solves the key distribution and management problem of symmetric key encryption in an efficient method. Then the security of first stage BBEC encryption is …
