The characteristics of encryption/decryption algorithms (ciphers) and modes of their operation (modes) have significant influence on security and performance of computer networks. The common modes of cipher operation such as ECB, CBC, OFB, CFB, CTR and XTS provide various levels of data confidentiality; however, those modes do not provide integrity and authenticity of encrypted data, and, therefore, do not efficiently protect data against non-authorized access and/or malicious modification/tampering. The newest generation of cipher modes - Authenticated Encryption with Associated Data (AEAD) modes - provides confidentiality, integrity and authenticity of data in a single cryptographic scheme.
