  • Certi¯cateless public key cryptography was
    introduced to solve the key escrow problem in identity
    based cryptography while enjoying the most attractive cer-
    ti¯cateless property. In this paper, we present a secure
    Certi¯cateless encryption (CLE) scheme with short cipher-
    text. The ciphertext length is at least jmj-bit (the length
    of a plaintext) shorter than the existing CLE schemes
    while retaining similar e±ciency of computation. The new
    scheme is provably secure against adaptive chosen cipher-
    text attacks in the random oracle model.
