Identifier-based signcryption methods and apparatus are disclosed both for signing and encrypting data, and for decrypting and verifying data. The signcryption methods use computable bilinear mappings and may be based, for example, on Weil or Tate pairings. Known, efficient, signing/verifying processes (22, 25) are judiciously combined with particular encryption/decryption processes (23, 24) to achieve efficient, yet secure, signcryption methods. |
