What is identity(ID) based encryption?

By Admin on

• A public-key encryption system in which an arbitrary string can be used as the public key.Any personal information: • An e-mail address, a photo, and a postal address, etc • Any terms and conditions, such as a time etc • Developed by Adi Shamir in 1984 • However, the encryption schemes were not fully used or created until 2001. How it works: • Private Keys are generated by a third party Private Key Generator (PKG) • PKG publishes a public master key and retains the private master key • With the correct ID, users can contact the PKG to obtain the private key • This way, messages may be encrypted without a prior distribution of keys between individuals
