How to Strengthen Any Weakly Unforgeable Signature into a Strongly Unforgeable Signature
2006Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most signature schemes are randomised and allow many possible signatures for a single message.

Strongly unforgeable ID-based signatures without random oracles
International Journal of Applied Cryptography, 2009In this paper, we construct a strongly unforgeable ID-based signature scheme in the standard model (or without random oracles), with five signature parameters. The signature size of our scheme is smaller than that of other schemes based on varieties of the Diffie Hellman (DH) problem or the discrete logarithm problem.

Quantum Cryptography, or Unforgeable Subway Tokens
1983The use of quantum mechanical systems, such as polarized photons, to record information gives rise to novel cryptographic phenomena, not achievable with classical recording media: 1) A Verify Only Memory (VOM) that, with high probability, cannot be read or copied by someone ignorant of its contents; 2) the multiplexing of two messages in such a way ...

Unforgeable Watermarking Schemes with Public Extraction
2018A watermarking scheme consists of a marking algorithm allowing one to embed some information into a program while preserving its functionality and an extraction algorithm enabling one to extract embedded information from a marked program. The main security properties of watermarking schemes include unremovability and unforgeability.

Justified Unforgiveness: A Moral Case Against Silence, Neglect, and Forgetfulness corrects the overemphasis on the benefits of forgiveness and shows how unforgiveness is a morally appropriate – and at times morally necessary – response towards unremorseful and unrepentant wrongdoers, grave wrongs brought about by absolute evil, and situations where ...

Unforgiveness: Refining theory and measurement of an understudied construct
British Journal of Social Psychology, 2017This research presents a multidimensional conceptualization of unforgiveness and the development and validation of the unforgiveness measure ( UFM ). The scale was developed based on a qualitative study of people's experiences of unforgiven interpersonal offences (Study 1).

Proxy Re-encryption with Unforgeable Re-encryption Keys
2014Proxy re-encryption PRE provides nice solutions to the delegation of decryption rights. In proxy re-encryption, the delegator Alice generates re-encryption keys for a semi-trusted proxy, with which the proxy can translate a ciphertext intended for Alice into a ciphertext for the delegatee Bob of the same plaintext.
