 Nov 26 comment Speed up modular exponentation with fixed base and modulus I meant dependence between x and calculation time. Nov 26 comment Speed up modular exponentation with fixed base and modulus Sorry, what is θ(x)? Nov 26 comment Speed up modular exponentation with fixed base and modulus AFAIU it's not $1/2 log_2 N$ but $\mathrm{pop}(x)$ where $\mathrm{pop}(x)$ is the number of $1$ bits (Hamming weight). Am I right? Nov 26 comment Speed up modular exponentation with fixed base and modulus I want to know this "How big is the gain and what resources are needed?" The explanation in the blog is too big for fast understanding.

Jun 22 comment Is triple des similiar to RSA in that they message size is limited to the key size? @poncho lol block cipher must not be symmetric, should it? Jun 20 comment Is triple des similiar to RSA in that they message size is limited to the key size? @poncho And would you explain why? Jun 10 comment Is triple des similiar to RSA in that they message size is limited to the key size? Triple DES and RSA [b]are [/b] block ciphers. en.wikipedia.org/wiki/Triple_DES Jun 6 comment Is triple des similiar to RSA in that they message size is limited to the key size? One AES opeation can encrypt only one block, for every thing else you need modes of operations. Jun 5 answered Is triple des similiar to RSA in that they message size is limited to the key size? Jun 4 comment Which version(s) of SRP are in ISO/IEC 11770-4:2006? If you consider you local network secure, you can use plain text :) Jun 4 comment Which version(s) of SRP are in ISO/IEC 11770-4:2006? There is already TSL-SRP, what's the difference between it and ISO? Jun 4 comment Which version(s) of SRP are in ISO/IEC 11770-4:2006? Since SE is already impersonal and community-oriented, could you explain, why is ISO/IEC 11770-4:2006 so interesting? Jun 2 awarded Quorum
