May 31	comment	can we do double encryption of a message without first key? @thomas, i see your point , the encryption points should not derive $k_1$ so i rule out the approach 1 in my question. the points have only encryptions of $k_1$ but i want data to be encrypted with $k_1$ without decrypting it . may sound stupid but this is what am looking for
May 31	comment	can we do double encryption of a message without first key? double decryption wont work if $k_2$ is encryption of $k_1$

May 26	comment	sir,please suggest me an algorithm or method how can i improve the prediction based encryption method using randomization? yeah homework packaged as a question here , @rashmi, do some ground work before asking anything
May 16	comment	Is Functional Encryption about Access Control over encrypted data alone? in a way you are correct, prima facie there aren't any connections. but if we dig deeper, both allow some kind of function evaluation over encrypted data which is key, FE does not give output privacy where as FHE gives that is difference, if we find connections may be we can find better FHE solutions , because there are successful methods already in FE
May 16	comment	Is Functional Encryption about Access Control over encrypted data alone? search for a paper " on connections between FE and FHE".
May 16	comment	Is Functional Encryption about Access Control over encrypted data alone? in a way yes , am mixing it with FHE , as there are possible connections
