Explanation

Data integrity mechanisms verify that VPN packets have not been modified, corrupted, or tampered with during transit. In IPsec, this is achieved using HMAC algorithms (such as HMAC-MD5 or HMAC-SHA-1) that compute a hash digest of the packet payload using a shared secret key; the recipient recomputes the hash and compares it to the transmitted value. Encryption (A) provides confidentiality by making data unreadable, but does not verify it is unaltered. Authentication (B) verifies the identity of the communicating parties. Key exchange (C) securely distributes cryptographic keys. Tunneling (E) encapsulates packets for transport across a network. Only data integrity directly addresses the unaltered-data guarantee.
