This paper presents an innovative open physical and logical design for secure element grids. There is need for online services providing secure storage and tamper resistant computing resources. Secure Elements, typically under smartcard form factors, are widely used in bank cards or SIM modules The Internet Of Secure Elements (IOSE) project attempts to deploy on-line secure element grids, providing remote application uploads and TLS user interfaces. We introduce secure element processors (SEP) that perform bridge between ISO7816 and I2C protocol, and which support non blocking operations. We present a protocol enabling efficient support of secure element grid in multi tasks environment. Finally we present some experimental results
