1) The document discusses various identity-based secure distributed data storage schemes including atomic proxy crypto systems, identity-based crypto systems introduced by Shamir, and identity-based proxy encryption proposed by Ivan and Dodis. 2) It also covers identity-based proxy re-encryption proposed by Green and Ateniese where a proxy server can transfer a ciphertext from an original decryptor to a designated decryptor using a re-encryption key. 3) These schemes are classified into two types based on how the re-encryption key is generated: either by the original decryptor or by a private key generator.
literature survey for identity based secure distributed data storage
- 1. IDENTITY BASED SECURE DISTRIBUTED DATA STORAGE SCHEMES BY: N.SAHITHI.
- 2. LITERATURE SURVEY Atomic proxy crypto system where a semi-trusted proxy server can transfer a cipher text of the original decryptor to a cipher text for the designated decryptor without knowing plain text. It is used in e-mail forwarding. Identity based crypto system introduced by shamir. It is a system where the public key can be arbitrary string and secret key is issued by trusted third party. Identity-based proxy encryption (IBPE) was proposed by Ivan and Dodis . In these schemes, the master secret key which is used to extract secret keys for users is split into 2 parts one is sent to proxy server other is sent to user.
- 3. The user can decrypt cipher text with the help of proxy server, but these schemes are not secure against collusion attacks. Identity- based proxy re-encryption proposed by green and ateniese. Where proxy server can transfer a cipher text of original decryptor to cipher text of designated decryptor after he gets a re-encryption key. This schemes are classified into 2 types based on generation of re- encryption key i) Re-encryption key generated/computed by original decryptor ii) Re-encryption key generated/computed by private key generator.
