The article provides information on identity-based encryption (IBE) system designed to solve the shortcomings of public key infrastructure (PKI) encryption. A typical PKI requires users to register with a certificate authority to receive a pair of keys that encrypt and decrypt messages. IBE systems do not require users to register to access the encryption mechanisms but instead allow them to rely on unique identifiers. IBE systems automatically revalidate all keys so companies do not need to revoke key addresses.

    Universal Re-encryption allows El-Gamal ciphertexts to be re-encrypted without knowledge of their corresponding public keys. This has made it an enticing building block for anonymous communications protocols. In this work we analyze four schemes related to mix networks that make use of Universal...

    In a proxy re-encryption (PRE) scheme, Alice gives a special information to a proxy that allows it to transform messages encrypted under Alice's public key into a encryption under Bob's public key such that the message is not revealed to the proxy. In [14], Jian Weng and others introduced the...

    The Visual cryptography scheme (VCS) is a perfect secure method that encrypts a secret image by breaking it into shadow images. A distinctive property of VCS is that one can visually, without computation, decode the secret by superimposing shadow images. However, much of the contrast of the...
