Abstract:
Methods and systems are presented for detection of malware such as worms in which a network switch entices the malware into sending scan packets by allocating one or more ports as bait addresses, sending outgoing bait packets, and identifying compromised hosts that send unexpected incoming packets to a bait address.
Abstract:
A certificate registry system is configured to issue authentication certificates to each one of a plurality of information providers and to maintain a root certificate corresponding to all of the authentication certificates. Each one of the authentication certificates links respective authentication information thereof to identification information of a corresponding one of the information providers. Each one of the authentication certificates includes a respective Instant Messaging (IM) screen name information of the information provider. The authentication certificates of the certificate registry are associated in a manner at least partially dependent upon at least one of a particular type of information that the information providers provide, a particular organization that the information providers are associated with, a particular type profession in which the information providers are engaged and a particular geographical region in which the information providers are located.
Abstract:
Various exemplary embodiments relate to a method and related network element including one or more of the following: receiving a plurality of advertisement messages via the communications network, each advertisement message of the plurality of advertisement messages including a set of meta-information which describes the content of an advertisement associated with the advertisement message; determining whether each advertisement message is relevant to the user by comparing the set of meta-information to a set of user preferences associated with the user, the set of user preferences stored locally on the user node; when an advertisement message is determined to not be relevant to the user, discarding the advertisement message; and when an advertisement message is determined to be relevant to the user, providing the user with access to the advertisement associated with the advertisement message.
Abstract:
A method includes receiving an authentication certificate of a voice mail account holder and/or an authentication certificate of a caller wanting to leave a voice mail message the holders' voice mail account. A voice mail apparatus that provides voice mail service for the voice mail account holder performs such receiving. The account holder and/or the caller are authenticated after receiving the authentication certificate of the party being authenticated. Authenticating the account holder and/or the caller is performed using authentication information contained within the respective certificate. After such authentication is successfully performed, a voice mail message record can be created in the account of the account holder. Such creating includes allowing the caller to store the message in the account of the account holder in addition to associating authenticated identification information of the caller with the message and/or providing authenticated identification of the account holder to the caller.
Abstract:
Malware detection systems are presented in which a list is constructed of enterprise hosts to or from which each given enterprise network host sends or receives packets within a current measurement period and statistics are accumulated based on two or more measurement period lists, with a count value being derived from the statistics to indicate the number of other hosts to or from which each monitored host sent or received packets, and one or more monitored hosts may be identified as suspected of being infected with slow and/or distributed scanning malware for which the count value exceeds a threshold value.
Abstract:
A certificate registry system configured to issue authentication certificates to each one of a plurality of information providers and to maintain a root certificate corresponding to all of the authentication certificates, wherein each one of the authentication certificates links respective authentication information thereof to identification information of a corresponding one of the information providers, wherein each one of the authentication certificates is devoid of linkage between the corresponding one of the information providers and e-mail address information thereof, and wherein the authentication certificates of the certificate registry are associated in a manner at least partially dependent upon at least one of a particular type of information that the information providers provide, a particular organization that the information providers are associated with, a particular type profession in which the information providers are engaged and a particular geographical region in which the information providers are located.
Abstract:
The invention relates to a system and method of hiding cryptographic private keys. While public/private key encryption systems are considered to be secure, the private keys ultimately must be stored in some location—in fact, in some digital commerce systems the private key is sent to the end user as part of an executable file such as an audio player and audio file. Thus, attackers can obtain access to the private key. The broad concept of the invention is to split the private key up into parts which are obfuscated, but still kept in a form that allows the encrypted data to be decrypted. One technique for obfuscating the private key uses modulo arithmetic.

Abstract:
Malware detection systems and methods are presented in which header data of protocol data units (PDUs) are examined at a wireless access switch shared by multiple clients, and the PDU type and client are used to establish counters, with the count values being analyzed to identify clients suspected of being infected with malware.
