Efficient Hybrid Proxy Re-Encryption for Practical Revocation and Key Rotation
Proxy Re-encryption Ciphertext Delegation Hybrid Encryption
2017/9/1
We consider the problems of i) using public-key encryption to enforce dynamic access control on clouds; and ii) key rotation of data stored on clouds. Historically, proxy re-encryption, ciphertext del...
A common requirement in practice is to periodically rotate the keys used to encrypt stored data. Systems used by Amazon and Google do so using a hybrid encryption technique which is eminently practica...
