Performance analysis of deliberately clipped OFDM signals
We analyze the performance of the clipped orthogonal frequency division multiplexing (OFDM) system in terms of peak power reduction capability and degradation of channel capacity. Expand

Conjunctive Broadcast and Attribute-Based Encryption
We propose a new cryptosystem called Broadcast ABE for both key-policy and ciphertext-policy ABE that can be used to construct ABE systems with direct revocation mechanism. Expand

Public Quadratic Polynominal-Tuples for Efficient Signature-Verification and Message-Encryption
This paper discusses an asymmetric cryptosystem C* which consists of public transformations of compIerity O(m2n3) and secret transformations of complexity O((mn)2(m + logn)), where each complexity is measured in the total number of bit-operations for processing an mn-bit message block. Expand

  • 1 November 2000
The performance of the strictly band-limited OFDM systems with deliberate clipping is examined in terms of the peak-to-average power ratio (PAPR) and the resultant bit error performance. Expand

Attribute-Based Encryption Supporting Direct/Indirect Revocation Modes
We present the first Hybrid Revocable ABE scheme that allows senders to select on-the-fly whether to use either direct or indirect revocation mode; therefore, it combines best advantages from both methods. Expand
