Advanced Encryption Standard (AES) OTriple DigitalEncryption Standard (3DES) oBlowfish oDigitalEncryptionStandard (DES) oInternational DataEncryptionAlgorithm (IDEA) o Stream Cipher is a symmetric key encryption method (meaning that the same key is used to encrypt and decrypt) in which the plaintext data to be encrypted is encrypted one at a time with a multi-bit key stream (also known as a cipherdigitstream). cipherdigitstream]), which eventually yields a ciphertextStream (ciphertextstream) o Since it is not encrypting fixed-length chunks of data, stream encryption is slightly less expensive than block encryption (where the complete encrypted block has to be filled in by padding).6.2 Cryptography 295Key management involves generating keys, verifying them, exchanging them, storing them, and destroying them at "end of life". This brings us to an example of the importance of key management. Two devices wishing to establish a VPN session send encryption keys in plaintext at the beginning of the session. If this were the case, then an attacker snooping on the key could use the key to decrypt the ciphertext into readable plaintext, which would result in a loss of confidentiality within the VPN.6.2.2 Symmetric and Asymmetric Algorithms,Remarks When the reader is building his or her vocabulary, the terms symmetric and asymmetric are important terms to distinguish between. The following will describe these two encryption algorithms, and will indicate which one is more CPU intensive, and which one will be used to encrypt blocks of data.
