Review of Aggregatable Signature Sample Clauses

Review of Aggregatable Signature. Based Broadcast Our ABE scheme is based on the ASBB primitive [32]. An ASBB scheme con- sists of the algorithms ParaGen, KeyGen, Sign, Verify, Encrypt and Decrypt. ParaGen takes as input a security parameter λ and outputs the public parame- ters π. KeyGen takes input π and outputs a public/secret key pair (pk, sk). Sign takes as input the key pair (pk, sk) and a string s, and outputs a signature σ(s). Verify takes as input the public key pk and the signature σ(s) of the string s, and outputs 0 or 1. Encrypt takes as input a public key pk and a plaintext m, and outputs a ciphertext c. Decrypt takes as input the public key pk, a valid string-signature (s, σ(s)) and a ciphertext c, and outputs the plaintext m. An ASBB scheme has a key-homomorphic property. This property states that, for any two public/secret key pairs (pk1, sk1) and (pk2, sk2) generated by running KeyGen(π), two signatures σ1 = Sign(pk1, sk1, s), σ2 = Sign(pk2, sk2, ⊗ ⊙ ⊗ × → ⊙ × →
