The DBLP (Digital Bibliography & Library Project) offers a good possibility to retrieve a list of all relevant computer science publications for a given author. Online available articles are usually linked as well.
Google Scholar is a search engine for scientific and citable sources.
The IACR also runs a publicly accessible ePrint archive. Since it is possible to publish there without going through a review process first, a little caution is advised when citing.
