Abstract
Architectures relying on a single central authority often offer a great efficiency but suffer of resiliency problems and are quite vulnerable to attacks. In our proposal, a Multiple-Authorities Key-Policy Attribute-Based Encryption scheme is constructed in which the authorities collaborate to achieve shorter keys and parameters, enhancing the efficiency of encryption and decryption, since the key creation requires the private secrets of all authoritiesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
