Cryptologia is the only scholarly journal in the world dealing with the history, the technology, and the effect of the most important form of intelligence in the world today - communications intelligence. It fosters the study of all aspects of cryptology -- technical as well as historical and cultural. The journal"s articles have broken many new paths in intelligence history. They have told for the first time how a special agency prepared information from codebreaking for President Roosevelt, have described the ciphers of Lewis Carroll, revealed details of Hermann Goering"s wiretapping agency, published memoirs - written for it -- of some World War II American codebreakers, disclosed how American codebreaking affected the structure of the United Nations.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
