Certificateless public cryptography
WebAl-Riyami and Paterson reported an encryption scheme that does not need a public key to address this issue. Similarly, Ma, Ao, and He [ 9 ] proposed a certificateless group signature to address the key escrow problem in ID-based group signature schemes. WebA number of variant systems have been proposed which remove the escrow including certificate-based encryption, secret sharing, secure key issuing cryptography and …

WebJul 31, 2016 · Certificateless Public Key Cryptography is a scheme that provides security by avoiding the key escrow and eliminating the drawback of identity-based cryptography. WebCertificateless Public Key Cryptography (CL-PKC) has very appealing features, namely it does not require any public key certification (cf. traditional Public Key Cryptography) nor having key escrow problem (cf. Identity-Based Cryptography). However, it does suffer to the Denial-of-Decryption (DoD) Attack called by Liu and Au [1], as its nature ...
