Electronic Code Book

Electronic Codebook (ECB) mode is a straightforward method of encryption that is commonly used in telecommunications in the UK market. ECB mode involves dividing the plaintext data into blocks of fixed size and encrypting each block independently using the same encryption key. While ECB mode is simple and easy to implement, it is important to note that it is not suitable for encrypting large amounts of data or data that has patterns, as it can lead to security vulnerabilities. It is recommended to use more advanced encryption modes such as Cipher Block Chaining (CBC) or Galois/Counter Mode (GCM) for stronger security in telecommunications applications in the UK market.
