Abstract:

   This document defines random-access authenticated encryption (raAE),
   a primitive that partitions a message into an indexed sequence of
   segments that can be encrypted and decrypted independently and in any
   order.  It also specifies SEAL (Segmented Encryption and
   Authentication Layer), a parameterized construction that defines a
   family of concrete raAE instantiations, one for each valid choice of
   an Authenticated Encryption with Associated Data (AEAD) algorithm, a
   key derivation function (KDF), and associated parameters.

   SEAL supports immutable (write-once), append-only, and mutable (in-
   place ciphertext rewrite) operations, each with per-segment
   authentication.  A separately configured snapshot authenticator can
   additionally authenticate the complete, indexed segment set.

   The document also defines the security notions of raAE, specifies the
   requirements for conforming constructions, and analyzes SEAL against
   those requirements.  Concrete cipher suites, serialization layouts,
   and test vectors for SEAL are specified in a companion document.
