Pairing.Error: unsupported right operand types: int, bytes, str

[RockyZhangHKU]

Hi, I meet an error when I runpython main.py like this. My environment is Python 2.7.12 , Charm 0.42 and Ubuntu (16.04)

Traceback (most recent call last):
  File "main.py", line 42, in <module>
    main()
  File "main.py", line 29, in main
    ctxt = cpabe.encrypt(pk, msg, policy_str)
  File "/home/rocky/Desktop/ABE-master/ac17.py", line 203, in encrypt
    prod1 *= (hash_table[j][l][t] ** row[j])
pairing.Error: unsupported right operand types: int, bytes, str

Does author meet this error before? I am wondering whether it it caused by the Charm version?

@sagrawal87 Same error here , same configuration as Rocky before. Any solution so far?

[sagrawal87]

Hi. I haven't seen this error before. May be try the newer version of Charm, Charm 0.43, which I used. It can be downloaded from here.

Let me know if the error doesn't go away.

@sagrawal87 tried it with Charm 0.43 and still the same error

@emantas @sagrawal87 Hi, everyone, I also tried Charm 0.43 on my Mac OS(High Sierra10.13, Python 2.7.11). After Installing GMP 5.x, PBC, OpenSSL, I download the Charm-Crypto-0.43_Python2.7.tar.gz (Python 2.7 Source) on my laptop, when executing "make", I meet this error:

@sagrawal87 Hi Shashank, can I ask you which is your Charm 0.43 version? Charm-Crypto-0.43.dmg (Mac OS X 10.6+ Installer) or Charm-Crypto-0.43_Python2.7.tar.gz (Python 2.7 Source)？Have you test your code under Charm-dev?

[sagrawal87]

The DMG file is an easy way to install charm. Just download, extract, and follow the instructions in README-OSX.rtf. I think dependencies like PBC, OpenSSL, etc. are automatically taken care of.

Hi Shashank, Thanks for your response, well, I still failed in my Macbook, but then I have deployed it successfully in my Ubuntu 12.04 with Charm 0.42 and Python 3.2.3. The AC17 and BSW07 scheme has been tested correctly. 👍 But there is another issue about CGW15 and waters11 scheme. I will open a new topic to talk with you more.

@samandeepdhindsa18 Could you say which version of Charm and Python are you using?

[samandeepdhindsa18]

Hi Shashank,

I am using Python 2.7.16 and Charm-Crypto-0.42-Python2.7 Version.

Note: I am finding listed error while using ac17.py but not in bsw07.py. So now my code is in running state.

Thanks & Regards, Samandeep
