Is there an asymmetric One-Time-Pad?
No there isn't. First, OTP is private-key encryption scheme. Second, Asymmetric key is public-key encryption and No public-key encryption scheme can ever be perfectly secret. This is because the public-key (used for encryption) is available to everyone and is related to the secret-key in some way. Thus, a certain negligible amount of information is leaked. However, this leakage implies it isn't perfectly secure. So, No such thing as asymmetric OTP.
