In this form of encryption algorithm, every individual block contains 64-bit data, and three keys are used, where each key consists of 56 bits. Which is this encryption algorithm?
In Triple DES, each data block is 64 bits. It uses three keys, each of 56 bits (though the keys are often provided as 64 bits with 8 bits used for parity, effectively 56 bits).
Characteristics of Triple DES (3DES):
- It operates on 64-bit blocks of data
- It uses three 56-bit keys (K1, K2, and K3), effectively providing a key length of up to 168 bits
- The encryption process involves three operations: encrypting with K1, decrypting with K2, and encrypting again with K3 (Encrypt-Decrypt-Encrypt or EDE mode)
